INTRODUCTION During the spring of 2018 a series of international conferences and an exhibition of posters about contemporary architecture and project experiences with natural materials was held at the Center for Mediterranean Architecture in Chania, Crete. Architects from diverse countries, mainly European and Ibero-American, exhibited projects realized mainly in earth, wood and straw, integrating concepts of sustainable construction. Nothing more contemporary than this could be proposed in the global environmental situation: a renewed look at how to help build a better world, based on natural principles.

This project’s philosophy is nothing new. Reflection on the impact of human action on nature has roots as deep as Eastern Taoism and expressions in modern architecture such as Wrightian organicism or the metabolism of the Japanese architect K. Kurokawa. The new generations of architects are increasingly aware that their action determines the environmental problems of the future. It is estimated that around 40% of the world’s energy consumption comes from the construction sector. How not to be scandalized when we witness a festival of high-end technological architectural works that leave a fatal footprint of greenhouse gases on the planet in their production? The British scientist J.Lovelock raised in the ‘70s in his thesis Gaia (the Greek Mother Earth goddess), the idea that our planet could be likened to a cell. It is susceptible to external processes and actions that alter ecosystems, but it has a capacity to be restored by a principle of resilience. The question is, what is the limit of the point of no return? Our first professional ethical duty is to safeguard life in our ‘big house’ by contributing with new solutions.

To resolve this question we were invited to participate in this cultural activity: an exchange of experiences, principles and solutions with those who think in a similar way. There were both important recent architectural experiences and some more long-standing ones. All of them undoubtedly build a collection that must be valued and considered in its true contribution and dimension. We must integrate this new way of building into modern ways of living. It is necessary to reformulate the seismic-resistant, acoustic and hygro-thermal behaviors based on scientific progress, as well as the treatment of waste under the criterion of a circular economy. We must apprehend these projects coming from a large part of the world, those that have developed in different cultural, geographical, climatic and human contexts. This is the final value of this meeting of two worlds. I congratulate the Greek organization PILIKO, instigator and manager of the idea, for such a laudable purpose and all the institutions that have supported it, with the hope of repeating it on a new frontier with new and better experiences.

ABOUT PILIKO “Piliko” was created in summer 2008 by professionals who specialize in the field of construction and who share a common interest in building with natural materials and sustainable architecture. Since 2011 “Piliko” has been a non-profit organisation with the aims to: • • •

Promote environmental awareness in the domain of sustainable design and construction; Document vernacular construction techniques and assess their contemporary relevance; Research new methods of building with natural materials and convey this knowledge.

Driven by these aims the group is involved in and organises the following activities: • 12

• • • • • •

Informative and educational lectures and exhibitions open to the wider public. Hands-on construction workshops in collaboration with experts open to students and professionals. Workshops open to children. Documentation and archiving of the Greek earthen architectural heritage. Coordination and participation in research projects. Counselling on scientific and legislative issues related to construction with natural materials. Coordination and participation in international networks for information exchange.

Piliko has organised more than 7 major construction workshops in Greece and abroad. These were taught by, or co-organized with, established experts (or organisations) in earthen architecture aimed at teaching professionals (mainly engineers) techniques of building with natural materials. Several workshops have been offered to national and international students of the Technical University of Crete (T.U.C.), unemployed people and primary school pupils. In collaboration with T.U.C. and the Centre of Mediterranean Architecture (C.M.A.), Piliko has organized two more conferences in the past (2011 & 2013) with invited speakers from Greece and abroad, open to the general public. Within the field of research, Piliko has participated in various events and delivered research work. Piliko, open to networking, has set concrete links to: • Associazione Internazionale Citta della Terra Cruda (Italy); • Red PROTERRA, Ibero-American network of Earthen Architecture and Construction; • Technical University of Crete, School of Architecture

CONTEMPORARY ARCHITECTURE & NATURAL MATERIALS Exhibition - C.M.A. 2018, Chania In this complex and hyper-technological age, the question often arises whether we can produce architecture with the use of simple building techniques and processes, with natural raw materials like clay. This exhibition attempts to answer this seemingly simple question by presenting projects from diverse geographical regions and environmental conditions. Before that, a basic question that begs for answers is this: why should we seek the use of natural and recyclable materials in architectural design and construction? There is a significant environmental cost caused by the vast utilization of processed material products of the industrial and post-industrial eras, in opposition to natural materials which most often meet sustainability criteria. Moreover, the use of natural building materials has been documented since prehistoric times, thus accumulating valuable cultural significance. In an effort to showcase the use of natural materials in construction, the “Piliko” team has invited architects, civil engineers and design teams that specialize in natural construction and its various techniques, to present their realized projects. We deeply thank them for their enthusiastic response. The projects that are being presented could be split geographically into the following 3 groups: the Balkan Peninsula (mainly Greece), Western Europe, and South America. Concerning the type of the project presented, the following groups emerge: conservation and promotion of existing earthen buildings, experimental construction projects and new projects.

The Tezekevleri project was initiated in 2016 by Aysun and Mehmet Sökmen on the Gündönümü dairy farm near Istanbul. It is an experimental natural building project unique in Turkey, and part of the broader 8bin100 Project. Three houses based on the same plan (4x5m) are built using different materials for the outer walls: slipstraw, strawbale and adobe bricks. Once completed a study will be made by monitoring sensors in the buildings over a year to compare their thermal efficiency. The bathroom building has a unique design with 4 showers and 4 toilets articulated around earthbag and slipstraw walls, topped with a large wood frame roof. Water heating and electricity are both solar. The toilets are dry, two of them with a filtering system directing grey water to a purifying pond. All shower walls are waterproofed with colored tadelakt lime plaster. Workshops are organized every year to help build and finance the project.

The School is for 780 pupils, comprising Preliminary, Primary and Secondary Education, 7.700m² on a plot of 15.748m². The realization process is at the final stage of the detailed design. Designed with a holistic approach and bringing nature into the built environment, it applies all aspects of passive low energy eco-design and incorporates principles of ancient and vernacular local architecture. Using regional resources and low embodied energy materials, a healthy environment is achieved. The building’s latent breathing is ensured and any moisture of the indoor air is released. The excavation soil is being utilized for the construction. It has been tested by the specialized, certified Building Materials Laboratory of the Aristotle University of Thessaloniki, School of Civil Engineering. Laboratory tests were carried out for the preparation of stabilized earthen blocks, as well as manufacturing instructions. Earthen blocks are used for non load bearing walls. Furthermore, timber is used for roofs and outdoor spaces, stone (a material found in abundance in Crete), reeds and pressed earth. The insulation is wool. Roofs and many walls are planted with endemic species to improve the microclimate.

The residence has been designed for a 4-member family. It is a one-storey house with a loft that has been constructed outside the dense residential net. The load bearing construction is a timber frame of columns and horizontal beams, anti invasion diagonal beams and plywood diaphragms. The 30cm thick external walls have been built with light clay of ~500kg/m³ weight. A secondary wooden frame has been used during construction of the light clay walls in order to hold the shape and to decrease the distances between columns and has been incorporated in the construction. The internal walls have been built from mud bricks that have been produced by the workers on site and dried in the sun. Both internal and external walls contribute to the internal climate of the building: light clay walls provide very good thermal insulation and mud brick walls ensure the necessary thermal capacity. All internal vertical surfaces, except high humidity spaces, have been plastered with clay plaster. Lime plasters have been used on external walls, bathrooms and kitchen 25

The design of this new residence in the traditional settlement of Vafes, Apokoronas, in Crete, attempted on the one hand to satisfy the modern criteria of sustainability and on the other hand to integrate organically into the existing residential area. The building typologically follows the traditional architecture of the settlement adjoining one side of an existing building, and communicates with the other two existing buildings creating an inner courtyard within the complex to which it belongs. The main two-storey tile-roofed building has been constructed using the technique of a wooden carrier with a lightweight mixture of straw and clay. The construction of the lightweight straw and clay was made by unskilled laborers after being trained by the supervising engineer of the project and with the help of a secondary wooden frame. External lime plaster and internal mud plaster complete the final surfaces of the building, which are finished with lime paints in earth colours. The two small ground floor sections of the building which are slightly underground and house the kitchen and bathroom, have been constructed with masonry bearing brickwork made of heat insulating bricks and their roof is accessible from the upper floor. 27

The brief of ESA was for it to be a low environmental impact building as it would house sustainable business activity. Various parameters were taken into consideration so as to come to the final sustainable design: No tree, bush or rock formation would be removed from the land, thus designing the building around these features and the orientation of the building would be used to achieve natural lighting, cooling and ventilation. Natural materials with low embodied energy and good thermal insulation properties would be used throughout the building process. Furthermore, throughout the construction of ESA, various workshops and seminars took place: local architecture students were informed and actively involved in the making of adobe mud bricks, strawbale workshops were organized where expert strawbale constructors shared their knowledge and trained architects, engineers, local builders and individuals to build in this way. The participants had the opportunity to learn old building techniques and apply them to a modern structure. 29

The building is a 2-storey house, with a timber horizontal roof, floor and terrace. The timber load bearing system is specially designed in order to withstand static and dynamic loads. The walls are composed of straw bales incorporated in a post and beam timber system, reinforced by diagonal timber elements. For the connection of the timber elements and the anchorage of the whole building to the masonry foundation, bolts and 2 types of steel bases were designed in order to be used in every position, for simplicity during the construction procedure. The timber part was built in 13 days with 2 carpenters. The areas around the openings were constructed with plywood boxes filled with straw, while all the windows and doors were made of timber. Clay reinforced with straw was used for the first layer of the plaster and lime for the final ones. The building presents a very good thermal behavior during all seasons and exhibits remarkable characteristics concerning the humidity levels indoors, due to the natural, breathable materials used (strawbales, clay, and timber).

It is a two-storey naturally built house, which consists of a ground floor of 85m² and 40m² mezzanine, in the “Vamvakia” position in Agria in Volos. The building’s basic synthetic principles are similar to the traditional standards in morphological level. The building is adapted to the low slope of the ground, giving two bedrooms and the kitchen/dining room with auxiliary spaces on the ground floor. Upstairs is placed the “winter living room” whereas the “summer living room” is in an outside space, overlooking the Pagasitikos gulf. The main body of the structure consists exclusively of wooden frames, “Larsen Truss” type, filled with a mixture of straw and clay thus forming a harmonious whole. Our main goal is to have a “healthy home” with breathing load bearing walls, natural building materials, wind ventilation and no VOCs which follows the principles of bioclimatic architecture.

The preexisting house is situated on the edge of a hill plateau at 513m altitude. It is a stonemasonry traditional longhouse of ground floor space with a basement. The planned addition consists of 2 sections: one of a bathroom, corridor, kitchen space (25m²) and the other a living room of 25m². The total addition has a unified bearing structure of reinforced concrete foundation and timber frames with 2 interlinked sloping roofs with tiles. The kitchen/bathroom space is built with infill walls of DiY insulating system and it is directly attached to the initial house. The new living/dining units are built mainly with adobe brick and rammed earth walls. For the earthmade construction, the excavation soil was used, enriched with sand, more clayey soil, natural straw according to each type of wall composition. The whole manufacture of 1300 adobe bricks and 2 rammed earth walls, each of 1.60x2.00x0.50m was done by the owner, the project engineer and friends. Gaps of slender wall sections (thickness of 25cm), such as on the diagonal braced openings, were filled with industrial materials (aerated porous blocks, insulating panels, glass bricks). info: https://www.facebook.com/countryhouseme/

This is farmhouse of not small size embedded in the natural environment, at a farm of 1,5 Ha combining modern materials, in the foundation and basement made of reinforced concrete and metallic supporting structure, with walls with a filling of natural straw & clay. Extended research preceded on which of the main natural building ways, cob, straw ball, straw & clay, waddle and daub, earthbags, would be the most suitable for a particular building in this place and in order to serve both the needs and ecological concerns of the owners. As the size is not so small, the metal structure is selected in order to combine the natural result of the straw & clay with the high quality of a contemporary building. So there is no need of a scenographic or a traditional approach. However the result is very interesting because of the artistic and spontaneous interventions of the owners. On the ground floor there is a big living room with the kitchen and on the first floor are the bedrooms. The main door leads you to a natural balcony of rocks just outside the building. The colour of the metal frame is the same as the olive trees all around and the colour of the walls is very near to that of the soil. 37

This 150 year old house has been renovated upon the request of its owner. It is situated in the picturesque village of Shipkovo, a thermal bath resort in Northern Bulgaria. The house has solid stone foundations and wattle and daub walls. The first intervention was the addition of a big wooden terrace to the South, arranged on two levels. The carpentry work was executed by local timber builders. Then we proceeded to the plastering of the house from the inside. The old plasters were removed and replaced with thin reed mats and an earth plaster. The reed mats act as reinforcement of the plaster structure and prevention from cracking in the future. Once the earth plaster was dry, a thin finishing coat of lime plaster was applied to the walls and the ceilings. The exterior walls were insulated with 5cm thick reed mats and finished with a thin lime plaster. The earth mortars were prepared on site from pottery clay mixed with fine sand. The lime used was calcic lime in powder form. The last part of the renovation was the pouring of a lime sand and perlite slab that was finished with fired ceramic tiles. The materials used guarantee perfect insulation and a good humidity exchange for the walls.

Earth and lime have been used for the finishing and decoration of buildings since most ancient times. The plaster is the last touch applied to a wall but it is also the first layer in contact with our senses. Beautiful interiors and nice facades influence our mood and the way we feel. They help create warm and cosy interiors and expressive facades. The book “Natural plasters and paints” is intended for the Bulgarian audience. It presents the qualities of earth and lime for decoration and the basic knowledge for mixing, applying and finishing natural plasters for inside and out. Natural plasters and paints are: • easily available; • totally recyclable; • non toxic; • regulating air humidity; • permeable to water vapor ; • easy to apply; • easy to repair ; • beautiful; • compatible with other natural materials; • a connection to our traditions.

SBAM.it (spazi di bambu italiano) is an ongoing project aiming at understanding and valorizing those species of bamboo that can grow in the mediterranean climate for construction purpose. It includes research and training activities as well as the realization of small demonstrative projects. Besides the use of whole bamboo canes, several experiments proved fabrics of bamboo strips to be an efficient and inspiring way of using the “vegetable steel”, to build lightweight load bearing structures. Several kinds of gridshells can be generated with bamboo strips. The pavilion in Gravina di Catania, as in some former projects, follows a triaxial pattern. This geometry, which is derived from Asiatic weaving patterns, provides strong surface structures without additional materials for joints or nodes. Pure friction provides stability. As an additional benefit this makes it easy to reuse the building material several times. For outdoor applications, the shells can be covered with canvas or shingle surfaces. 43

Innesto is a little pavilion which has been grafted into an abandoned concrete building in the small town of Casaprota, central Italy. It can host cultural activities and has the ambition to start a renovation process in this part of the town. The structure was built during summer 2017 as a training result of Learn - BIØN, an international building workshop on sustainable architecture. 15 participants from seven different countries have learned and applied construction systems based on wattle and daub and light earth techniques. The applied wall systems have been designed to cope with the local climate. The combination of raw earth layers with insulating layers of straw or wood fibre panels provides a balanced inner climate throughout the year. The surfaces are finished with clay and lime renders. Most of the used materials such as raw earth, reed canes, timber and straw have been sourced locally. A further design purpose was to explore the possibilities of combining self-construction with digital prefabrication. The wall system Quincha Digital allows for complex geometries thanks to numerically controlled prefabrication processes but can be finished easily by hand even by untrained builders. 45

The house, called Borgocapo, is a temporary residence and a raw earth technical laboratory. Built in the traditional massone technique: layers of small clay and straw bricks. The existing building is one of the 800 cob houses cataloged in the Abruzzo regional house census. There have been repurposed, in the two existing buildings, the original techniques and recovered materials amongst the demolition of superfluous materials. The soil was dug on site, the project idea is the simple linear approach with the loggia positioned in between the various section and the two floors. The enlargement uses a supporting wooden structure unified to the raw earth walls which are based on brick and stone. Various techniques have been used: adobe, clay and straw bricks dried outside on site. The cut raw clay bricks were made in one of the few raw earth operative ovens to be found in Abruzzo; the cob, used without being molded into the brickmassone form. The roof is lightened with straw bales or straw mixed with clay. 47

1997 saw the beginning of the Abruzzo Regional Census regarding inhabited and uninhabited earthen houses for the most part in the Chieti, Pescara and Teramo provinces, involving forty regional councils resulting in the registration of eight hundred earthen houses. Casalincontrada with its 122 earthen buildings is the council with the major concentration of this architectonic, historical and cultural heritage. In 2008 the Casalincontrada council bought the number 7 registered earth house, situated in c.da Fellonice, later named Teresa, after the last owner. For seven years the house renovation became a permanent laboratory site. The building’s typology is similar to that of a classical rural house. The construction technique is that of cob or bauge (massone): clay, straw and water. The recovery project saw the reuse of the traditional building techniques enhanced by those of modern and building site technology.

TIMBER

Following the earthquake of the 6th April 2009, the inhabitants of Pescomaggiore wanted to find a way to remain in their town but did not know how. The main aim consists of providing a new home for families that became homeless after the earthquake. The project, started in June 2009, is called E.V.A., an acronym for Do it Yourself (DIY) ecovillage. The project features seven houses built on a section of land located at a short distance from the original village of Pescomaggiore, which is now abandoned. There were two priorities in “Progetto EVA”: first, to redefine the professional-client-builder relationship through a participatory process, and second, to build low impact owner built houses. The involvement of the local community is essential to this project. EVA is a practical alternative to the governmental C.A.S.E. Project and it aims to take on reconstruction through participatory planning. BAG identified in the straw bale building the ideal technological tool to pursue all the above mentioned targets simultaneously. The houses have a simple wooden structure and straw padding, the roofs are clad with solar panels and there is a system to collect rainwater. The straw allows the inhabitants to build houses quickly in emergency situations, allowing for a DIY approach.

Piazza Gasparotto Urban Living Lab is a complex project where, since 2014, the cooperative EST has been supporting a reactivation process of a square which at the time was completely vacant: 2200m² of public space, unused. From that moment on, other subjects joined the regeneration process and today they are not only supervising it, but they are also contributing to change and improve it. The “Culturability” competition funded some activities such as the summer collective construction site where the citizens participating together with all the associations involved, extended from the planning phase to the implementation phase, creating a fundamental moment to share the reappropriation of a public space. Citizen builders had the opportunity to make additional “lastminute” improvements,making the project more updated and more attended. The project involved the expansion of the urban garden area, the creation of a space for parkour activities and for organizing events, the new arrangement of some existing flowerpots and the placement of new seats and ashtrays. The Bright Totem stands as a symbol for the reappropriation of the area. It is constructed with a timber frame, and with the application of wood to wood joints has been able to eliminate the need for diagonal bracing elements.

STONE WALL

Renovation and expansion with sustainability techniques of an old and rural building located between the terraces. Landscape: Stone terraces contain the land for cultivation. Architecture: stone cladding walls contain an interior skin of raw earth. This combination of architecture and landscape is expressed both in the composition of the insertion of new volumes in the anthropized slopes, and in the internal function of transpiring leather and thermal inertia for the summer mitigation of the Mediterranean climate. The hygrometric regulation of the earth is accentuated in the bathrooms through the creation of ceilings and false ceilings that increase the collection surface. Wavy shapes of the ceilings create spaces of living organic architecture from both the perceptive and functional aspects. For the thermal inertia function the internal plasters are put in place with considerable thickness to incorporate the electrical systems without creating traces in the walls. This solution guarantees the energetic and structural performances of the perimeter supporting masonry. The project also involves the use of innovative prefabricated earth panels that guarantee remarkable mechanical performance. The prototypes for a new production line were used only in some rooms on the ceiling and walls. The frame wall shown below combines a wooden structure with earth panels in the ground and insulating fillings deriving from agricultural byproducts (hemp shives and rice husks). The use of raw earth techniques in the new construction intervention combines ecological and hygrothermal performances with material and formal aspects. The sinuous walls of the living room seats converge with the conical fireplace towards the kitchen and then towards the rooms on the upper floors.

NEW LIFE FOR A PEAT SHED 698m², GERMANY, Schechen

Architect, sustainability and energy concepts Roswag Architekten, with Guntram Jankowski (LP 1– 5), Eike Roswag-Klinge (Managing Director Andreas Wendt, Project Leader, Planning), Mauricio Ramírez (Planning), Tiago Rocha Damasceno (Planning and Building Works) Structural planning, earth building consultancy Ziegert | Seiler Ingenieure, Uwe Seiler (Structural Planning), Christof Ziegert (Earth Building Consultancy), Christian Vorwerk (Structural Planning), Lars Fechner (Structural Planning) Survey Tobias Mattes

The clients had already dismantled the historic peat shed in Kolbermoor, thereby avoiding the planned demolition and disposal of the historic timber structure. At the new site in Schechen, the former peat shed forms a harmonic and pleasing ensemble with the nearby station and existing outhouse building. The project occupies an empty brownfield site in the village and thereby intensifies the existing neighbourhood and prevents the need to occupy unused landscape. The mixed village area enables the logical combination of living and working programs in one building. The design concept was developed in close collaboration with the clients as a self-build project. The shed was placed on the western edge of the site thereby creating a large and well lit area to the east. The newly integrated house and workshop is offset from the load bearing axis of the historic structure allowing its almost complete retention and enabling its visibility. The structure is primarily expressed through the freestanding columns and beams. An interior connection between the two programs was not planned; instead, to the west and south, the wall of the new construction moves into line with the historic structure leaving a gangway that accesses the workshop and parts of the storage areas. To the east the new wall moves outside of the structure and opens the house to the garden through large openings. The workshop in the north part of the building has direct access to a storage area for willows and other weaving materials. The floor plan orientates itself to the east facing garden and terrace with large full height openings. The structure of the peat shed was reassembled true to the original with damaged elements being replaced or repaired using traditional carpentry techniques Only the foundation is adapted to the new program requirements through the addition of a new floor slab.

On the 4th September 2007 the architects Anna Heringer (Mag. arch. Linz/ Salzburg, Austria) and Eike Roswag (Dipl.Ing. Architect, Berlin, Germany) were awarded the Aga Khan Award for Architecture 2007 for the “ School handmade” project in Rudrapur, Bangladesh. The school made of earth and bamboo was constructed for and with the Modern Education and Training Institute (METI) and the NGOmother organisation Dipshikha in 2005. METI promotes the individual abilities and interests of the schoolchildren and trainees taking into account their different learning speeds in a free and open form of learning. It offers an alternative to the typical frontal approach to lessons. The architecture of the new school reflects this principle and provides different kinds of spaces and uses to support this approach to teaching and learning. On the ground floor with its thick earth walls, three classrooms are located, each with their own access opening to an organically shaped system of ‘caves’ to the rear of the classroom. The soft interiors of these spaces are for touching, for nestling up against, for retreating into for exploration or concentration, on one’s own or in a group. The upper floor made of bamboo is by contrast light and open offering sweeping views across the surroundings, its large interior providing space for movement. The view expands across the treetops and the village pond. The use of earth and bamboo as building materials draws upon traditional building techniques with technical improvements. They demonstrate how locally available resources, abilities and labour can be used to build cost-effective and better buildings. 25 local labourers were trained in the new techniques.

The Healing Garden extends an existing Trauma Therapy Centre in Chamchamal, a town originally populated through forced resettlement in Kurdistan - Iraq. The Jiyan Foundation for Human Rights provides contemporary trauma therapy for the victims of war and persecution in the region, particularly women and children. The Foundation is based between Berlin and KurdistanIraq. The project was initiated in Chamchamal, where the local therapists expressed a desire for new healing spaces beyond the existing facilities; spaces suitable for new types of care. The design was developed as a DesignBuild cooperation between students and designers from ZRS, TU Berlin and the Bauhaus University The project emerged through a series of intense workshops in Chamchamal and Berlin between the Jiyan Foundation and the design team. The 45,000m² Garden will serve the community as a place of encounter for the neighbourhood and patients. The project puts a strong emphasis on the use of increasingly endangered traditional building materials and techniques. Thus, the new typologies reconnect the community with its pre-resettlement homes and cultural heritage. This act of reidentification with the past provides a way to ultimately let go of the stigmatisation caused by trauma. The first construction stage consisted of a series of buildings for animal assisted therapy. Completed in 2016, the first phase was designed and built under the ZRS umbrella and provided a chance to build up strong relationships with the locals. A master plan and series of other typologies including a bakery, community centre, workshop and clinic were developed as an integrated design studio between architecture and landscape design students. The next consisting construction phase is currently being developed as a cooperation between the project partners under the supervision of ZRS.

Our first choice for the project is the superimposing of both functions initially separated in the program, a business and medical premises, to build a volume more in touch with the constructions of the village. The plan is an L shape adapting itself to the party wall of the neighbouring house and leaving a small public place in front of the supermarket set back from the very busy road. The construction stretches out in the direction of the valley de la Dore, opening its main facades on both parallel mountains of the valley. A higher volume, on three levels, assures the transition to the North with the party wall of the neighbouring house and allows the opening of a glazed facade of roof, directed due south. Protected from the sun of the summer by an overhanging roof, it lets in the low sun of the winter which warms the big wall of rammed earth in double height. This stretched out space is a vertical hall from the entrance on the ground floor to the big space of the corridor of the floor. The plan of the floor answers this double logic, doctor ’s offices opened on the village and the mountain in the East, the circulation following the crossroads of the village and the mountains of Livradois on the West. 65

Architectural Notice. This project is the third unit of the House of the park. The original building is located along a very busy road. Logically, the extension that followed turned to the south. The new expansion project is not able to sink further into the marsh, and is implanted north of the current extension with a northeast/southwest orientation. The South orientation is thus obscured. The area of the project is at the limit of the flood zone. In order to comply with regulatory constraints, we have limited the constructed surface. The entire R + 1 level is reserved for the administrative and technical team while the DRC welcomes the general public. For this reason, the extension is placed on stilts. The entire distribution of workspaces is made from the outside (staircase and walkway). The whole is made available PMR thanks to the installation of an elevator. Environmental approach (Bioclimatic operation of the project). The East Facade is the most exposed to noise from the road. It consists of a wall in tonnage in order to protect itself from these nuisances. A glazed roof facing south leads to a meeting room. This room brings heat by a greenhouse effect. The collected hot air is redistributed throughout the offices through ventilation. The West Facade is a strong source of heat. In winter, it must capture calories and light. In summer, sliding shutters prevent overheating. High internal inertia, obtained by filling the floor and coating for partitions, helps to mitigate temperature fluctuations in the premises. The chosen materials are primarily healthy, local materials (straw, raw earth). The cladding materials are raw (Douglas, Galva, raw earth). They can easily be recycled. Technical description The materials used for this building are: Infrastructure (pilings) concrete, wood structure (coffered floor manufactured in workshop, wall, roof ), straw insulation and wood wool. A Wall Bauge 30cm thick provides acoustic comfort. The inner core earth brings inertia. The place of the systems is very limited: the building is connected to the existing pellet boiler which will provide the 3 kW of heating power needed in normal use. The extension will be heated during the off peak hours of the existing building, i.e. at night. The inertia of the building allows a storage and a phase shift of the heat. A double flow ventilation ensures a good distribution of heat and limits phonic bridges.

The project was developed together with the architect Oriol Rosselló for a construction of a reception area to host events in Mas Marroch, at the prestigious Restaurant Celler de Can Roca in Girona. We were requested to build traditional style cane panels in order to protect the dome from the sun. The idea of the coating is that it can be a base structure for climbing plants in the future and end up being a living plant protection. The whole work is done following sustainability criteria and applying traditional and conscious construction techniques such as dry stone walls that support the entire structure of wood and canes as well as other natural materials used in the building. The work faced a double challenge: design panels that could adapt to the curvature of the dome and installing these artisanal panels rising up to 20m high without great means of infrastructure performing vertical work in height.

This private kindergarten is built for a group of 15 children from 3 to 6 years old and run with the Montessori pedagogical system. In order to reach a sustainable and economic solution for the building the following courses of action were adopted: a) using locally available natural building materials (timber from the nearby forest, strawbales for the walls, clayey soil for the walls and plasters, river gravel for the foundation, earth and grass sods for the green roof ); b) using nonrecyclable waste products (used car tires for foundation, plastic bottles for floor insulation); c) creating earthquake resistance by using ductility of structure; d) avoiding the use of cement; e) saving energy consumption and heating costs by passive solar heat gain, high thermal insulation and usage of a rocket stove run with dead wood from the surrounding forest; f ) long life span with minimal maintenance. The kindergarten was built in only 5months for less than 70.000€, costing much less than a conventionally built kindergarten in the area.

The straw bale wall preserves the heat. There is a gain of 3°C in the winter time: while the outside temperature drops 12 degrees when it gets dark, the internal temperature drops just 2 degrees in the same duration of time. The north windows are 30cm wide and take up the full height of the interior space so that the solar radiation is projected in greater depth without overheating the interior. The continuity of the natural light gets projected through cylindrical skylights. Both designs leave their trace on the floor pattern with pavings of different textures that sketch these sources of light. To sum up, the house aims to obtain its heat as well as its permanent illumination from the sun as an efficient energetic engine.

We wanted to develop the use of local materials of low contained energy and low environmental impact, such as the recycling of wheat stubble and raw soil. We made laboratory tests to evaluate a building solution called “lightweight wattle and daub” with a whitewash of clay appropriate for Chile. The evaluation enables the official certification for fire resistance, thermal and acoustic transmittance and Atterberg Limit, for the tested wall. This enables the utilisation of this technique in public projects. It can be used when rebuilding households after an earthquake or a fire, using local workers. We built a partition with a timber frame of 2” x 4” beams, both sides of the wall were covered by electro-welded mesh. We filled up the frame with dry wheat straw. We plastered both sides with clay until we got a total width of 15,1cm. The results of the thermal test were: thermal resistance (Rt) of 1,42m²k/W and thermal transmittance (U) of 0,70W/m²k; the results of the acoustic test were of 47dB acoustic reduction.

A church, a parsonage, and a graveyard are the elements that organise the space in a village to be built in the Chilean Patagonia, currently home to just six families. The assignment was to build without using nails. This building and the noble timber of the region will be a sort of “Carpentry Handbook”, a practical foundation for a local “Carpentry School”, ensuring the transmission of this knowhow to future generations. This project is inspired by a historic Chiloé church. It uses its architectural and building features, with the addition of contemporary technologies: thermal insulation, lighting, air conditioning, acoustic efficiency, and fireproofing. A work of architecture is conceived to be lived in by its inhabitants, who, in order to make it their own, will proceed to imprint it with their tastes, needs and beliefs. In Vodudahue, certain architectural features, the religious iconography, the furnishings, and the Carpentry School are to be decided on and carried out with the active participation of the inhabitants, i.e. the “local culture” that was needed to carry out the project of a wooden church built without using nails. 103

The ground floor house opens to the north (the sunny orientation in the south hemisphere), in a fan form, with radial lines centered behind the house. The program consists of a bedroom, an open space of kitchen and dining room, a living room as a home cinema, and finally, an open study space. The semibasement garage below this study gives it a special relation to the outside and the ‘home cinema’ living room. All the structure, except for the garage, is made of wood framework with a grid - metal on both sides, filled with straw on the south walls and earth/straw on the remaining walls. The inner density was selected to offer thermal insulation or thermal inertia, depending on the orientation of the wall. The same materials were used on the roof construction, filled with 40cm straw and lime powder, in between earth/ straw layers. The ceiling is finished with wood strips and lime, or in the case of the kitchen, earth plaster. The walls are finished with lime or natural coloured earth plaster.

Compositionally, the vertical volume and the vertical placement of the wood is related to the highest trees of the terrain and the activity in movement (public spaces); and the horizontal character of the volume of mud is related to the stability and the appropriate silence for the bedrooms. On a plot of land in the Ecological Community of Peñalolen, surrounded by many native and introduced fruit trees that have not been cut, but have even caused last minute volumetric adjustments during construction. The materials play an important role, visually being a part of the landscape, but also due to the economy and efficiency that results when used as a filling and coating of the walls, coming from the same land obtained from the excavations for the foundations and other earth movements. Both volumes close their facades to the south (southern hemisphere) and open to the north to obtain the best possible light from the sun. The south façade has a parallel line of cabinets to improve thermal insulation.

This project consists of the rehabilitation of an old house in the historical center of Abrantes, Portugal. The existing single family house gives place to 3 different apartments. The facades were kept almost as they were, except for the roof. The attic was transformed into a usable living space by the construction of large dormers. The design of the conversion to a multi-family house tried to keep the most of the pre-existing structure, reinforcing it with steel columns and beams that connect walls by a peripheral beam structure on each level. The original structure of mixed stone walls was maintained. However, the wood structure was quite damaged by rainwater. The interior partitions of wood and earth lime plaster were reconstructed with the same materials: the 7cm partition walls gave place to 15cm walls with earth/straw or cork filling, finished with lime plaster. For the expansion walls on the roof, the same materials were used: a timber framework with an earth/straw filling and lime plaster. The floor and roof structures are also made of wood with earth/ straw insulation. The brick walls of the ground floor could be kept, reconstructed and reinforced.

STONE WALL

This house was built originally as a family house in the heart of Barichara, in the year 1850 approximately. Barichara has been a Colombian Heritage site since 1975. In the year 2007, the design process and the restoration started to transform this house into a Boutique Hotel. In this project worked not only architects, designers and engineers, but also some artisans and local builders who still have the knowledge of how this rammed earth house was built. It was a privilege to work and learn from these talented people. The result is a small hotel immersed in a colonial style shell, which will offer the comfort of modern architecture to the future guest. The house was built originally with rammed earth walls, that the project restored and protected with the local plastering made with horse manure, earth and lime. The subdivision walls were made of ECB (Earth Compressed Blocks). The roofs needed special attention because some parts were very damaged. The project used the central patio as the quiet area for the guest, and the backyard as the social area. One of the damaged roofs was changed for a roof terrace to have the view of Barichara. 111

STONE WALL

El Caney is located at two kilometers from Barichara, a town recognized as a Colombian Heritage Site since 1975 because of its well protected colonial architecture and traditions. The plot is situated at 1320m above sea level, so it has a regular temperature of 23 Celsius degrees, all year long. It also has a semidesert landscape. Due to its location, the project has a panoramic view of the town and its surroundings. The design starts from the typology of the traditional construction of the region, a tobacco shed, “El Caney “, whose structure allows the wind and the sun to dry the tobacco and protect it from the rain and humidity. It is built with local traditional techniques such as rammed earth, wattle and daub, and stone walls. Through the reinterpretation of the farmer ’s tradition, and the revaluation of the local construction techniques, the project developed its own language between tradition and modern style. The project’s footprint took main importance, therefore it not only uses recycled materials such as wood, and roof tiles, but also all the earth employed to built, comes from the site. We gave main importance to harvest rain water and filter all the gray and black drainage. 113

Piedemonte is located in the countryside, one hour from Bogotá, Colombia. Due to the stress of the Capital, the owner wanted to have a place for the weekends where she and her family would be able to relax surrounded by nature. Also with the possibility of relocating there in the future. The conditions of the site where very important for the design: 2600m² above the sea level; cold weather most of the year, and very low temperature at night. Average wind from the mountains. The design is located on the south/north axis so the house can collect sunlight in the walls and roofs during the day and radiate it into the house at night. Another important decision was to have thick walls in the perimeter to have a good thermal inertia (low tech bioclimate). The techniques used for the construction where Earth Compressed Blocks (ECB) and stone walls. The roof structure is made of cultivated wood and clay tiles. The ceiling is in bamboo sections. The majority of the workers were local and so also were the materials. Some of the interior doors were recycled from demolished houses in Bogotá. The project has a mix between rural Colombian houses and modern Colombian style.

This project was realized with the concept of “progressive development” in Villa de Leyva / Colombia. It is located in the rural Andean area, 5° 37 ‘59 “N, 73° 31’ 32” W, altitude 2200m.a.s.l. The average temperature is 18 degrees Celsius, a semidesert climate. The philosophy of the project: create a “sacred” space to grow, consecrate a nest, and integrate the microcosm to the macrocosm, providing a connection from “heaven to earth”. It was designed with sacred geometry, as part of a regular pentagon, with a five pointed star that is drawn on the floor with the Golden Section. The first stage of construction was a “loft”, a unique space, and shelter under a dome of earth, seven meters in diameter, built with blocks of compressed earth, for walls and roofs, and made with the CinvaRam and soil of the place. At the time the concept was the “return”, a look inside, the reconstruction of being. The second stage expands, a moment of opening, light, and there, new techniques are integrated with ornate brick vaults of the Mexican tradition, organic forms. Materials: earth, lime, sand, round wood, bamboo; for a healthy, economical habitat with low environmental and energy impact.

Demonstration project in Villa de Leyva / Boyacá / Colombia. Coordinates: 5° 37 ‘59 “N, 73° 31’ 32” W. It is located in the Andean area, at an altitude of 2149m.a.s.l. The average temperature is 18 degrees Celsius. The “dialogue with the earth” is like an experience of approach and awareness with natural materials. The philosophy of the project began by amalgamating the work to the place, respecting the topography and adapting to the terrain, resulting in technical and spatial innovations. I integrate elements such as land, air and water; I include stone with fossils and plants; all are local resources and materials. The design starts from geometric polygons in order to generate volumes with the domes and vaults built in raw earth block, some with formwork and others with the Nubian technique (Africa). Today, after 27 years, this is a house in perfect condition, liveable, cozy, with excellent thermal and acoustic comfort, which demonstrates the quality offered by these materials, proven as a living laboratory. One of the innovative aspects is the application of lime, used in the production of BTC, in mortars, in all walls and roofs, as well as in the coatings of the project.

Ecosystem: Andean forest at 2,600m.a.s.l., average temperature: 15 degrees Celsius. Eco-sustainable design, multipurpose space of 90m², 2 bedrooms, services, 2 bathrooms, cellar and terrace lookout. The project is integrated with the native forest; it is built with compressed earth blocks made in situ. It is projected as a school of art and life, aware of the forms of construction, seeks to demonstrate solutions, use the “form as structure” with an innovative roof of a brick dome without formwork,mexican technology; double walls in “real” rigging, thermal and acoustic system. Since the beginning of the project it has included ecotechnologies of natural bioconstruction with earth, wood, management and applications of lime use, harvesting of rainwater for consumption, biological pool, ecological sanitation. Properties of local natural materials: earth, round wood, lime for coatings and mortars. The philosophy germinated from the reconnection with nature in architecture with organic expressions and actions of good living: “slow life”, to live in the present, and a shelter to “take care of life”.

The project is located in a rural area , in an ecosystem of Paramo at 2850m.a.s.l. in the coordinates 4° 56 ‘0 “N, 74° 11’ 0” W. It is a municipality located in the savannah of Bogotá, 38 km west of the Colombian capital, the average temperature: 13 degrees Celsius, humidity 70%. The conceptual axis is the sustainable design, dialoguing with the place; some parameters were raised under the analysis of the life cycle (LCA) of the materials and procedures. An ecological premise is the consumption of natural resources. The use of energy and water is rationed, and the emissions generated by its components are evaluated and executed in order to see a work with low impact on the ecosystem. A new approach is the roofing of low environmental cost, applying the form like structure like professional search. There are six forms of roof design without form-work, in two types of blocks, raw and baked, a technique developed in Mexico. There are two houses intended to disseminate technological innovations in a contemporary design and construction, with ecological vision, thinking about clean production, from the execution, use, useful life to the reincorporation to the environment in its final phase.
