Bonjour!

May I introduce myself?

Dreams and needs of people constantly change. So does the world they live in. We as architects create spaces for these people and determine new ways of life and work to accommodate them. But we also shape their dreams and needs. This is the beauty of architecture.

During the last past few years, I have been an architect on the Faroe Islands. And designing in such a unique environment taught me how to push the boundaries of architecture. Creating spaces on this small archipelago amid the North Atlantic Ocean enforces you to think carefully about wind directions, storms, and lack of natural light during long dark winters but also its abundance during short bright summers. It shifts focus onto a building’s interior for Faroe Islanders spend most of their time inside. Rough outside conditions make it all the more important that its interior design creates a cozy atmosphere and enjoyable environment. It should inspire human interaction and make them feel good.

This experience has also shaped my ideals and ambitions as an architect. It taught me to keep my architectural designs in harmony with nature. I constantly return to nature to find inspiration for new rhythms, shapes, effects, and motifs. I seek to create spaces that surprise their visitors. I want them to shift their focus to unusual patterns or discover new perspectives on ordinary things in unexpected ways. For instance, changes in focus may reveal versatile shapes, unexpected openings, or a sudden incidence of light.

My work is informed by a place’s history. Each place tells a different story. I want my architectural designs to make these stories heard. I want its visitors to learn about, appreciate, and identify with a place, its particularities, peculiarities, idiosyncrasies. A design has to accommodate their needs but ideally also represents an optimal environment for inspiration and encouragement.

The history of a place also tells us what can last there. Learning about traditional ways to build can help us find solutions to challenges we face in a project and improve upon them. I am passionate about combining traditional with modern ways to build and creatively translating old ideas into new forms. This approach permits us to conserve what already exists while accommodating the dreams and needs of future generations.

My architectural work is cheerful, curious, courageous. It is sustainable and creates spaces that serve people’s needs. But it also shapes their dreams.

The Faroe Islands are a remote archipelago amid the North Atlantic Ocean. Their gateway to the world is the sea. For Faroe Islanders, a harbor thus not only stands for farewell and return but also trade, progress, and opportunities.

Molin - the Faroese name of the harbor of Tórshavn. Molin lies on the outskirts of the capital of the Faroe Islands, which is home to about 21,000 people, and is the first landmark to be seen when reaching it by sea. It is visible from most parts of Tórshavn thanks to the town’s hilly landscape.

This industrial site is the location of the new ferry terminal plus the ferry line headquarters and its cargo warehouse. The combination of these three functions in one building complex in addition to one IPSE border was unseen before in the Faroese architectural landscape. It clearly stands out as a new landmark on the map. This project expands the walkable city center into former industrial areas, reclaims them for the public, and allows its modern visitors to experience the city from a forgotten perspective - the sea.

The architectural expression is inspired by both the breathtaking nature of and the traditional ways of constructing on the Faroe Islands. Traditional Faroese houses consist of a heavy stone base topped with a light wooden structure and a grass roof.

Sudden changes in weather rarely seen elsewhere can create a spectacular variety of lights on the Faroe Islands. This dance of lights is emphasized through wooden and concrete lamellae, which rotate along the façades. The resultant effect is a perpetual change in the building’s appearance depending on where you look at it from.

Physical and mental abuse is a phenomenon that occurs in all social spheres irrespective of religion, nationality, and age. This may lead to clashes of personalities with different backgrounds inside a refuge for battered women. It requires architecture adjusted for this perculiar context. The purpose of its design is to provide space that the women and children require for their healing process. It helps them overcome perceptions of being an outcast and offers opportunities for communication and interaction.

The central aim of this concept for a women’s shelter is to provide a common space which encourages interaction between dwellers through a variety of distinct arrangements. This variety is achieved through different layers inside the women’s shelter.

The first layer creates private spaces for women or families. Wooden cubes contain the basic needs for living. There are four of these cubes evolving through the whole building. These cubes together with the stairs do these cubes carry the ceiling panels.

Portfolio Linda Dwinger 16
Space and Interspace
Layer one : private space L ayer two : common space inside Layer three : common space outside
Concept axo

The space in between these private rooms divides the common zone into warm and cold areas. These common spaces are defined through their functional relations, program sequences, forms, alignments, exposures, scales, and accessibilities. Therefore, they are contextualised in different ways and appear different on every level.

The pedestal lies above street level. This is on the one hand, due to the annual recurrence of floods in Passau. On the other hand, it produces a barrier between dwellers and pedestrians, and provides a hidden entrance for the women.

In its function as a public entity, which does not has to be hidden from the pedestrians, the kindergarten and nursery is located on the ground floor. In this context, the wooden cubes carry the functional rooms, and the space in between arises as a moving surface for children.

Hence, the in-between space on this floor spreads vertically rather than horizontally. Ramps, slides, caves and climbing walls evolve. These spatial structures challenge children every day anew and support their curiosity in discovering their environment.

The property is located at a special place in the city of Passau. It lies in an area between the old part of the city and housing estates where its design is not required to meet any conditions.

Accordingly, the building is developed from the inside to the outside. Railings surround the common outdoor space. The common indoor space features a glass façade at the waterside and is covered in polycarbonate at the streetside. In the private rooms, the women and children can adjust the degree of their privacy through an external curtain.

OY is the short version of the Faroese word “oyggi(ar)”, which is equivalent to the Englishword “island(s)”. In this project, the word OY draws the picture of a “time-out island” for the mind - an island for having a pint, a bite and a laugh. OY is the result of a gathering of faroese entrepreneurs, dreaming together of delicious food, great entertainment, and first and foremost…excellent beer.

All of those joys are combined under one roof in the industrial area of the capital of the Faroe Islands, the town of Tórshavn. This roof hused to be a venue for trading wood for many decades before a fire in the beginning in the early 20th century left some major damages inside the building. Since then, it has been vacant. The simple functional structure of the building has remained, as well as its raw industrial appeatance It has got a makeover using graphics on the industrial material. New features for various purposes have been added to the existing structure... Now the building hosts four different amenities:

A brewery with a capacity of about 1.2 million litres. A shop for selling the freshly brewed beer of OY.

A bar, mainly selling beer, which is brewed in house. A restaurant serving delicious authentic barbecue.

And it becomes a BREWPUB.

Floorplan

The architectural concept of the brewpub offers guests the opportunity to not only enjoy beer and food but also experience the whole brewing process The floorplan puts emphasis on the bar in the center of the brewpub. On a plateau slightly elevated above ground level and thus invites guests to gaze at the heart of the brewery – the brewhouse. Guests are sitting on the plateau surrounded by the brewing kettles. The entire brewpub has a rather rough appearance. All building materials have been skilfully assembled to accentuate its industrial atmosphere. Graphical signs on the floor and walls point guests to the different areas of the building. Those graphical signs feature the most important national birds of the Faroe Islands. You can also find them on the OY beer cans.

Portfolio Linda Dwinger 26

As much as possible has been built by the entrepreneurs themselves, since the budget was tight and most of them are carpenters. It was necessary to find either cheap material or material that was suitable for reuse The idea of using beer cans from the brewery for both the walls’ and the ceiling’s cladding evolved gradually in response to these constraints. Tables and benches were made from steel and wood leftovers.

The Faroe Islands are located far north in the nordic hemisphere and therefore characterized by very long and dark winters. Hidden in the industrial part of Tórshavn, the brewpub will become visible especially in those dark times thanks to a translucent extension of the front facade. Made out of polycarbonate and illuminated from the inside, it appears like a lightbulb on the night sky. This extension also serves as a windcatcher and can be used to host more guests.

Project: Supermarket

with cafe and take - away

Location: Argir, Faroe Islands

Type: New Construction

Size: 1000 sqm

Status: Sketchproposal

Office: Henning Larsen Architects

Concept design : Linda Dwinger

Supervision: Ósbjørn Jacobsen

SIMPLE IDEA:

Argir is a suburb of Torshavn situated on a hillside south of the town and it offers a great view over the capital. Over the last years this area has been developed significantly. New houses, apartment buildings, office buildings and a school have been built. The need for a supermarket close by as well as a place to enjoy lunch urges.

LOGISTICS :

Existing cliffs

Street towards housing area

New busstop

Street towards housing area

The site for this new supermarket – Á-handil - is characterized by a strongly sloped terrain and frequent heavy western winds. The idea for the design is to cut out of the landscape the required square meters for supermarket and the parking lots. In a next step, the box for the supermarket is put on the upper site and covered with a green roof to both hide it in the terrain again and protect it from the winds reaching over the mountain. Wooden pillars around the supermarket carry the roof and create a wind and rain protected path around the building. The distances between the wooden pillars vary along the façade and get wider in front of the different entrances.

Parking Street towards city

Path devoted to truck (storage-entrance)

ARCHITECTURAL EXPRESSION :

By rotating the box under the roof result slightly narrower and wider parts along this path. In the more spacious parts the added functions of a cafe and a take-away gain both an outside sitting area. The exposed cliff will remain visible under the outside roof along the pedestrian entrances. By lightning the path and the wooden structure, the building will be visible like a cut in the mountain from the bigger part of Tórshavn.

G- festival is an annual art and music festival taking place in the Faroese village of Syðrugøta - home to around 400 souls and surrounded by a breathtaking landscape. For this occasion, we designed and built a pavilion in one of the four music areas of the festival.

Located in the ruins of a factory for dry fish, that burned down some decades ago, the site features a rough and robust character. The light and simple design of the pavilion reflects the opposite to its surrounding. The pavilion is to serve as an elevated plateau with a roof. It permits a better view of the stage and landscape. It is a place to relax and sit or dance and enjoy the music while being protected from potential rain.

This small project featured issues of a usual construction site at reduced scale:

Limited amounts of money, shortages of time and manpower, lack of both material and tools and, of course, extreme Faroese weather conditions.

We therefore developed a design that permitted an efficient and pragmatic building process. The plan involves simple wood connections and light elements that can be lifted by only two people without the support of a crane or scaffold. Affordable wood with as little as possible different dimensions has been used. Measures have been calculated with the aim to make most efficient use of the available material with as little as possible remains. The flat roof allows the strong North Atlantic winds to pass through without lifting it.

Lusaka, Zambia 2013

The Technical University of Munich together with the University of Zambia developed a prototype of a school building that is suitable for cities as well as for rural areas. This prototype aimed to be not more expensive than a common school building in Zambia at this time. Also, it was important for it to be realizable out of mainly renewable and locally available materials. Hence, the project needed to be conceptualized in a very sustainable way.

According to the 2011 Human Development Index, the UN developed tracker of a populations well being, Zambia is ranked 164th from 187 nations in terms of its population’s wellbeing. Especially the education sector has shown large deficits. Therefore, the Zambian government introduced a project called „10 000 classrooms“ to improve conditions in schools across the country.

The project’s aim was to improve regional sustainability standards for school buildings focusing on indoor climate conditions, energy conservation, sanitation, and resource consumption. At the Technical University of Munich, a few bachelor’s and master’s

theses focused on those topics. As part of my studies in civil engineering, I dedicated my bachelor thesis to this project and and conceptualized a biogas plant for prototype schools in Zambia. The aim is to achieve more self-sufficient schools, which can use organic waste and wastewater for producing their own electricity for cooking and light.

The thesis is about the application of a biogas plant for wastewater treatment and biogas production for local use at Woodlands Primary School in Lusaka, Zambia, where a prototype plant was built. The prototype is evaluated regarding its potential to treat wastewater and to produce biogas as a replacement of fossil fuels in the context of local options. To write this thesis relevant information was compiled and evaluated from respective papers and monographies.

Portfolio Linda Dwinger 46

An interview as well as an email correspondence with local experts was also a valuable source of information. This way theoretical knowledge was linked with technical expertise and tested for its practicability and relevance. The prototype is a fixed-dome digester, which can be built with local building materials and skills, runs with low maintenance efforts and very efficient.

The process of fermentation produces biogas and depends on the feed material. Biogas is a scentless, smokeless and non-toxic fuel, consisting of 50 – 70 % methane, 30 – 40 % carbon dioxide and other substances in low quantities. The quality of biogas is determined by the content of methane. The generated biogas at the school will primarily be used for cooking. A gas stove burns 200 – 450 liters of biogas per hour depending on the biogas quality and the stove’s efficiency. Suitable and sufficient feed material of suitable organic content must be put into the biogas plant to reach the required yield.

For an optimal anaerobic decomposition of organic matter, a process that occurs in a four-step process compounded by Hydrolysis, Acidogenesis, Acetogenesis and Methanogenesis consists a few operating parameters which have to be controlled. The temperature in the digester works only satisfactorily by mesophilic conditions about 20°- 40°C,the optimum pH for a generally stable process lies in the range of 7 and the recommended hydraulic retention time range from 10 to 40 days. The substrate fed into the digester needs an optimal C/N-ratio which is represented between 20 and 30:1 and an adequate liquidation. The solid content of a stable anaerobic degradation is between 7 and 11 %. Some compounds at a high concentrations can result in an inhibition of the anaerobic process. Typical inhibitors can be Oxygen, hydrogen sulphide, organic aids, free ammonia, heavy metals and other hazardous substances.

For the prototype at Woodlands Primary School, human excrement is used as feed material for the biogas plant. It yields up to 20 liters of biogas per kilogram. Other feed materials, such as animal feces, vegetable and fruit waste, or industrial wastewater, can be added to increase yield. Besides fuel for gas stoves, biogas can also be used to generate electricity.

I discuss several maintenance and control mechanisms in my thesis In addition to the biogas, the digestate is another valuable product resulting from the anaerobic treatment process. It represents a nutrient-rich fertiliser. I also expand on alternative systems of wastewater treatment - amongst others, Septic tanks, Anaerobic Baffled Reactors, and Planted Drying Beds - in case a biogas plant is not suitable in each context.

Sandsteinscheune is the German expression for a barn made of sandstone. This particular one presents an excellent example for the time and region it was built in. It was built in 1843 and is located at the end of a traditional barn quarter shaped like a horseshoe. It can be found outside the town of Kemnath in Oberpfalz, a region of Bavaria in Southern Germany. This barn was originally built for drying and storing grains but had been abandoned until recently a young family wanted to renovate the barn and turn it into their new home. In this way, they wanted to inspire also with the idea of inspiring others to come along and revitalise this abandoned quarter with new life.

Due to its location next to a small creek, the first level is elevated one meter from the ground to protect the grains from floods and parasites. The delivery zone through an arch opening is at street level. Small holes in its heavy stone walls allowed the air to flow through for drying grains and removing moisture inside. Thick sandstone walls surround the simple floorplan and its wooden roof structure follows a plain design.

We developed a holistic concept to restore the building’s original appearance based on intensive research and in accordance with the regulations of Bavaria for the preservation of historical monuments. We chose a split-level floorplan that allows sunlight to shine through the whole building thanks to vertical openings. It permits us to preserve the barn’s existing structure while having its roof’s build-up displayed to the greatest extent possible.

The pest infestation in the ceiling beams and roof construction was eliminated by thermal treatment without any removal of material or use of chemicals. The exterior sandstone walls received a thermal insulation plaster including a wall heating on the inside, to maintain the exterior apprearance. A light floor heating system has been installed in the floors. Its walls and doors have been treated with lime.

The owners of the building did as much work as possible themselves and have done a beautiful job in developing an interior design concept. Their Instagram profile offers an opportunity to catch a glimpse of it: #die.sandsteinscheune.

The Faroe Islands are treeless by nature due to cool summers, strong west winds, and frequent gales. In some sheltered plantations, however, locals are trying to establish a tree plantation. One of these places is the tree nursery of Tórshavn, which is located in the district of Hoyvik north of the capital. The farm is right next to a main road running into town, but well hidden in the greenery, becasue of its location three meters below street level.

The staff of the tree nursery needs a small office building for administrative tasks as well as a small kitchen and a venue for selling plants to the costumers. Its design should not extend 100 square meters, respect the existing tree population, and has to be resistant to the rough weather conditions and still be affordable.

The building has a simple shape but features a pergola at its entrance to both blend in with its green surroundings and protect it from the rain. A green roof is added that extends the storage shed’s roof, which already existed. It also provides shelter at the car entrance. The interior design features a Scandinavian look. Wooden walls together with calm colors on the floor and partly on walls and ceilings give it a fresh ambiance.
