what we do 11

The building is located on a 350m2 plot near the center of Athens and houses the offices of R.C.TECH. The basic design principles were the consistency with the firm’s architectural work and vision along with the sustainability of the building. The design is characterized by simple geometry,

functionality in spaces and extensive use of modern and efficient materials and systems.

The building is developed in five levels along the East-West axis allowing natural light to enter the building in a controlled manner, thus creating a feeling of comfort to its users. Technologies and design strategies regarding sustainability include: - Optimal orientation for the building and its openings - Active and passive solar systems for cooling and heating of the building lowering energy consumption and increasing the feeling of comfort - Sun-light control unit with aluminum louvers along the building’s west face - High-end aluminum window framing and low-e; glass facades for minimum thermal losses - Use of ceiling capillary system for cooling and heating of the building - Full external thermal insulation reducing the number of thermal bridges. - Aluminum sheet covering for the buildings north face for wind break effect - Regulation of building’s condition through an electronic Building Management System (BMS) - Use of green roofing The construction was partly funded by the European Union through a subsidies program for the design and construction of sustainable buildings.

family residence Dionysos Athens


The house is designed to accommodate a family of four and is located in a plot of land measuring 900 sq.m. in the northern part of Athens.

It is split in 5 levels, each one accommodating a different function of the family. In the lower level, one can find parking space and all the mechanical systems. The indoor swimming pool is located in the next one overlooking the front garden. The living room with the kitchen and the dining room are placed on

the ground floor, giving a unique view to the Penteli Mountain in the South. On the first floor are the bedrooms and finally on the upper -attic level, one can find a more secluded office space. All of materials used on the interiors are based on the owners desire for a ‘warm’ spatial experience. Planks of oak wood are used for the floor while wood decking like the ones found on sailing yachts has been used for the areas surrounding the swimming pool, the office and certain areas in the garden. Locally quarried



The design of the foot bridge is based on a single brush stroke. A strong dynamic line that emphasises the lightness of the shape giving the bridge a strong visual identity. The structure provides a unique reference point to the area, supporting the effort to attract development and help unify the two sides of the Sheffield Parkway.

The footbridge consists of a steel arc structural system fixed to two reinforced concrete embankments, offering a high level of stability to the users. The Lighting design has been incorporated into the structure, following the single stroke over and under the bridge, allowing the shape to stand out in the darkness. Lighting channels follow the curvature of the supporting structure emitting a soft glow and creating a unique lighting solution. The width of the foot bridge fluctuates between four and six and a half meters providing generous space to both foot and equestrian traffic. The parapets are made of laminated glass with a smoked gradient, giving an opaque surface until 60cm and then gradually turning transparent as it reaches its final height of 1.8m. The entire path follows a gradient of 1 in 15. In collaboration with JASON SPILIOTAKOS ARCHITECTS

borgo summer house Kythira


The medieval settlement of Borgo Serato (Messa Vourgo) and its wall surrounds the northern part of the Venetian castle of Chora in Kythira. The settlement is practically an open archaeological site with old houses and numerous Christian orthodox temples (privato) belonging to various families of the island. A small residential complex of two houses in this area, with very interesting architectural characteristics, was succesfully restored by R.C.TECH. Features

such as thick stone walls, small openings and different roof levels compose the geometry of the two houses; a geometry very familiar to local architecture. The restoration of these two old houses was performed through the preservation of the buildings’ shell and with the help of local craftsmen and materials.

Elounda Crete


The house is located at Plaka in the Gulf of SpinalogaCrete. It is a family house operated on a year round basis. Capable of accommodating all of the family the complex consists of two levels being developed in the main building and an swimming pool area.

Chosen for their aging quality and local vernacular looks, materials like quarried stone and colored lime will blend with the simple, monolithic volumes that refer to the Cretan building typology. A 3m high wall, made of stone, is situated in the north-east part of the plot, protecting the building from the local prominent winds while also serving as a privacy barrier.

The general spatial arrangement follows the ground contours so the local landscape is not over-worked. On

the upper level, the swimming pool and the accessible roof garden can be found, overlooking the main house’s volume and the exquisite view towards the open sea. Moving down a level, the living and dining rooms but also the kitchen and a small office are all fitted in the ground floor level. A great veranda, conveniently situated next to the kitchen offers great views while also providing with a shaded outdoor area. Finally, the bedrooms and all of the storage rooms and garage are located in the lower level.

The aim of the design was to produce an elegant and highly

functional building. It consists of two parallel zones, one for office use

and the second for storage.

Sustainability and rationality were two key elements of the design. The structure is located in Metamorphosi and it is made out of steel covered externally with aluminum insulating panels. The shading of the building’s facades is achieved with the use of a horizontal louvers system. Their movement is adjusted automatically with the use of sensors that monitor the sun’s position. At the front side of the plot and along the building’s main facade there is an outdoor water pool providing passive cooling during summer and working as an emergency water tank in case of a fire.

Kythea Resort is a four star hotel complex in the island of Kythira and partly fills the need for high class tourism units on the island. The complex is equipped with 32 comfortable rooms with sea views, a large pool and vast public spaces - bar, sitting rooms, meeting room etc.

The design borrowed and redefined local traditional forms while at the same time using modern systems taking into consideration

the needs and specifications of a luxurious accommodation unit. R.C.TECH undertook both architectural and interior design work.


kythea kythea resort Kythira




This new shopping mall designed by R.C.TECH is located close to Athens in the suburb of Pikermi, right on the commercial road of Marathonos Avenue. It consists of a main building of 1.400 square meters.

Early on during the design process it was stated that the building should be an impressive landmark able to be distinguished in an area full of visual noise from the surrounding mixed-use buildings. It should also be a point of interest to the local market.

The architectural solution was based on the geometric characteristics of a speeding ferry boat, with its stern compart-

ment projecting over the street and shaping a protective overhang.

In the center of the plan, one can experience a more protected atrium surrounded by the glass walls of the shops. A round skylight on the floor provides with enough natural light the underground spaces underneath. The upper floor accommodates more shopping area while at the roof one can enjoy a drink from the roof-garden bar.

lagadia hill Kythira


In the position Liofyto near Kapsali, on a large plot of 5100m2, three houses were designed. The location is subjected to the distant but

strong presence of the Venetian-built Castle of Chora and so there was an effort for the three main volumes to be integrated as smoothly as possible in the landscape. The design is simple, mostly open planned but with distinct functions and clear references to the traditional rural

houses of Kythira. The landscape is characterized by scattered olive trees, small plateaus and old stone walls.



The Cavallini Residence or the “House with the Sundial�, as it most commonly known on the island, is a landmark building for the village of Avlemonas and holds all the characteristics of a significant monument. In close collaboration with the current owner, descendant of the Cavallini family,

R.C.TECH undertook the full restoration of the historic house, with great care and respect to its architectural features and unique history. The reconstruction of the house included a long list of works such as the reinforcement of the masonry walls, new plastering works and the restoration of various architectural features such as the sundial above the main entrance and the stone frames around the doors and windows. The aim of the architec-

tural study was to highlight the plasticity of the building and to reinstate the positive aura that the building holds. During this process, additional features showing the ingenuity of the

original design and the craftsmanship of that time, were kept and fully restored (e.g. the elegant setup of the rain water collection).



The house with the sundial Kythira


In the position Liofyto near Kapsali, on a large plot of 5100m2, three houses were designed. The location is subjected to the distant but

strong presence of the Venetian-built Castle of Chora and so there was an effort for the three main volumes to be integrated as smoothly as possible in the landscape. The design is simple, mostly open planned but with distinct functions and clear references to the traditional rural

houses of Kythira. The landscape is characterized by scattered olive trees, small plateaus and old stone walls.



This is a two-story house overlooking the gulf of Evoikos. This building

was one of the very first projects of R.C.TECH’s people

(Design Construction: 1986 – 1989). So, the renovation that was asked by the current owners of the house became immediately an inter-

esting design project; a revisit by the architect of the original study.

The request was clear:

the house had to regain its original

“aura” which was partially lost because of certain interventions that were

done and of the time that had passed. In particular the aim was not only to renovate but also to strengthen the original design by implementing features that were left out from the original study due to restrictions at the time of the original construction. The house remains modern and minimal, affiliated by the surrounding environment, providing the residents with privacy and an open view towards the sea.

Metaxourgeio Athens


The listed building on the corner of Paramithias and Thermopylon st. in Metaksourgeio was fully restored in order to host a fashion de-

signer’s modern atelier ( The building is devel-

oped in three levels and is a typical example of Athens’ neo-classic architecture, dating back to the beginning of 20th century. The basic ideas behind the new design were: -simplification of the building’s shell through the use of single coloring on the exterior surface and the creation of open spaces inside, replacing the existing small rooms and various compartments -successful implementation of modern amenities and functions in an old neo classic building -creation of clear forms, inside and outside, with long, clear lines and continuous spaces -flexibility in function and allowable activities The construction process involved, among other things, the reinforcement of the structural system, the replacement of the wooden roof, the placement of new doors and windows and the restoration of unique architec-

tural elements through the use of modern conservation techniques.



Millennium bank commenced its operations in September 2000 (under the brand name NovaBank) and has a network of 178 branches in Greece (150

Retail Banking branches, 25 Business Banking and Factoring units, and 3 Private Banking centers). R.C.TECH, in collaboration with architect Costis Perifanakis, was

assigned to design all of the bank’s retail branches along with the Business and Private Banking network. Provided with the corporate identity, expressed through the bank’s logo, colors and patterns, our designers came up with a design that uses a variety of materials such as granite, stainless steel, glass and wood along with the use of surfaces colored in yellow, red and white. The aim

of the design was to reflect the bank’s desire for innovative, fast and reliable services in everyday banking transactions but also to overcome difficulties pertaining

to the remodeling and/or conversion of preexisting spaces.

Artemida Village restoration Artemida-Peloponnisos


The fires of August 2007 in Peloponnesus hit hard the mountainous village of Artemida. The settlement comprises of many traditional buildings that were damaged heavily by the fires. In the context of the support and help from Cyprus to Greece, the Cypriot government undertook the Reconstruction and Restructuring of the local community of Artemida. In the project’s contract between the Cypriot government and J&P-Avax S.A., R.C.TECH undertook the

preparation of the architectural design for the reconstruction and restoration of 22 houses. Most of the houses are

two-story high, fairly impressive and positioned perpendicularly to the hypsometrical curves of the ground. The ground levels are typically designated for storage and animal containment while the first floor is the main residential area.

The Architecture of the buildings is characterized by the exposed masonry and the small symmetric openings. The roofs are typically sloped covered with roof tiles. The particular traditional elements of the buildings are preserved and still show the experience and aesthetics of the old craftsmen. These elements can be found at the roof’s finishes, the external stairs made out of stone, the dome structures, the fireplaces, the conches and the traditional wine press. The reconstructed settlement will provide a great deal of relief to the victims of the fires and its final state will elevate

the rich architectural heritance. In the design team with Sofia Kavala as the supervisor the following people participated: Sarah Rizou and Christina Kontou.

Athens is a city with extreme climatic conditions in terms of summer heat and dryness. The main problem observed in typical high rise buildings in Athens, is their overheating and lack of fresh air due to their tight exterior enclosure and their dependency on HVAC systems. The year round costs for cooling those buildings, absorbs more than 40% of their annual energy costs.

This proposal is based on the notion that by implementing the existing building with a second outer skin will minimize those costs by self ventilating and self shadowing the main building during the summer months. The new skin is equipped with variations of the same design component in the micro scale that creates areas of shadow and extra pockets of insulation. The global shape, is designed to manipulate the natural currents of air in order to self ventilate the building. This means that the shaft created between the existing building and the new intervention is an area the wind, in low velocities, passes by and thus the occupants can open the windows.


GREEN sustainable tower Athens


The trophy of any race is a reward that symbolizes victory. A memento that attempts to freeze and immortalize a great personal achievement in time. The design of this years Rally Acropolis trophy tries to capture this

very moment of victory as well as the route that this international competition has taken throughout its history and within the Greek Landscape. Its strict geometry is directly associated with ancient historic commemorative

stones which narrate important battles and events. Its material, the white marble of Dionysos, is the same marble used in the monuments of the Acropolis. Its wooden detail from the Greek olive tree functions to depict and imitate the Greek landscape and define Greek tradition. The piece of marble varies in thickness, exposing its monolithic nature and revealing its transparency as it gets thinner.The wood of the olive tree

flows into the surface and geometry of the marble while simultaneously provides a contrast with the whiteness the marble reflects.
