House STBR

FORM SOCIETY is designing the extension of a farmhouse in rural south-eastern Carinthia. The farmstead’s original residential building no longer provides sufficient space for its residents, as it is now home to four generations of the family. The new structure is set in line with and connected to the existing building.

The extension is being executed using hybrid construction, featuring a concrete ground floor set into the hillside and upper floors built in timber frame. The first floor houses the living and sleeping areas for the young family, opening out onto a generous covered terrace. The living space extends into the attic floor via a mezzanine. The facade and roof surfaces are clad in timber battens, with spacings that widen from bottom to top across the sections of the facade, defining the building’s distinctive character.

Community Hall „Um Breil“ Greiveldange

Community Hall „Um Breil“ Greiveldange

The new community hall in Greiveldange replaced its predecessor, which could no longer meet the current needs of its users. The two-story building serves as a rehearsal space for the local music ensemble and as a meeting venue for various community groups. Next to the building, the design comprises a terraced open space with plants and wooden seating areas, creating a new quality of public space. Together with its outdoor area, the community hall forms part of the rebuilt town centre of Greiveldange. The building’s crystalline outline is determined by its location at the intersection of several streets, and the resulting narrow construction site, and by the primary function of the large hall as a music rehearsal space. The roof’s shape creates the required ceiling height for the hall, defines the building’s form, and allows for the southern exposure of the photovoltaic system. The building’s large-format, patterned façade panels give it a striking design, reflecting its dynamic form. The building is located on a slope and is accessed via entrances on the ground and upper floors, which are connected by an exposed concrete staircase. The upper level contains the large hall, a small hall with a bar, and sanitary facilities integrated into the space as a box. The lower level houses the technical and archive rooms, as well as a multi-purpose room for the clubs to use. The building is naturally lit by its frameless glass façades. The combination of sun protection glazing and shading of the glass surfaces by loggias and cantilevered building sections means that external mechanical sun protection is not required. The building’s primary energy supply comes from renewable sources such as geothermal energy, which is used for heating. A photovoltaic system integrated into the roof, coupled with a battery storage system, ensures an independent power supply.

Villa FLa

FSY — Sun, 23 Jul 2023 12:11:07 +0000

Villa FLa

The design of the villa is based on an intrinsic geometric principle. The main construction area of the villa measures 15 x 15 m, and the floor plans are developed by rotating the base area by 5° within these dimensions. This enables the floor plans to be organised without being restricted by the orthogonality of the plot. The ground floor has been cut away to the north and south in order to create covered spaces for the entrance and terrace. The upper floor comprises four rooms connected by a communal area with an atrium placed in the middle. The atrium creates a spatial connection between the ground and first floors. The upper end of the building volume is shaped by the recessed storey. The shape of the facades is defined in depth by the boundaries of the building site, the rotation of the internal spatial organisation and the cut-outs in the building volume.

Villa Wey

Integrated into the hillside, this three-storey residence is accessed via Level 0, embedded directly into the slope. Above, the main floor rests like a platform over the terrain, cantilevering protectively over the entrance. Housing the primary living and sleeping spaces, the main floor opens seamlessly onto the garden. The dedicated parents‘ suite is located on the recessed top floor, creating a private retreat complete with a home office area and a bedroom with an adjoining dressing room and bathroom.

Villa SP

Villa SP

Villa SP is an implementation of a small house in the countryside. The house’s design evolves from an efficient use of space. The ground floor contains the living area and is designed as an open floor plan, zoned by steps that create a subtle horizontal transition. Part of the ceiling is opened up to extend the space vertically and reveal the dynamic line of the roof. The top floor houses the private rooms with an adjacent terrace. On the ground floor, a second terrace extends the living room into the garden, where a curtain wall serves as sun and wind protection while keeping mosquitoes away.

Pavillon Source Bel Val

Pavillon Source Bel Val

Design of a thematic pavilion by FORM SOCIETY in cooperation with artist Serge Ecker. The exhibition of the pavilion addresses the history of the again unearthed mineral spring of Bel Val in Luxembourg. In the late 19th and the early 20th centuries the water of the spring has been bottled and sold as Bel-Val table water in many parts of the world. In the second half of the 20th century the spring has been overbuilt by the ARBED steelworks and rediscovered after the demolition of the works. The pavilion is located in a park which is now part of the former industrial area.

Inspired by the circles formed by a drop on a water surface, the design of the pavilion is based on a diagram of interacting concentric circles defining the organization of the programmed areas of the pavilion. Links to the park, the local surroundings and the establishment of a visual axis to the location of the original spring add to the force field affecting the formal articulation of the pavilion. The exhibition is structured into five thematic sections with the spatial installation of “the hidden spring” in its center.

The pavilion is composed of three independent and demountable components: The exhibition, the canopy and the kiosk. This concept follows the idea of a phased re-use of the pavilion. After the exhibition is dismantled, kiosk and canopy can be used as a unit. The kiosk continues to serve the visitors of the park or it can be dismantled and rebuild somewhere else.

Villa C-UB

The building develops alongside the lines of the sloping terrain as a split level type villa. This mode of organization reacts to the topographical situation of the building ground and in further consequence responds to the spatial needs of the family and its individual members. The arrangement and the programming of the levels act as generator for the formal articulation of the building.

Community Hall “A Lannen”

Community Hall “A Lannen”

Located on the edge of a slope overlooking the town of Osweiler, the building mediates between the site and town as well as between the different programmatic needs of various groups that use the community hall for events and festivities. Partially embedded in the hillside, the building is conceived as a functional continuum consisting of the central hall for 200 people, the generously designed foyer, and the glazed front that provides a view of the site and establishes the main visual relationship towards the town. The building envelope forms a continuous interface. Its form envelops the inner cubature and responds to external conditions and requirements, such as the structural integration of a photovoltaic system for local energy production.

House JMJ

House JMJ

The design of the house is conceived as a metamorphosis of traditional forms which comply with local building regulations. The result of this process becomes especially appreciable in the interior of the home. The otherwise typical spatial division of ground and upper floor is overcome by an airy living room that establishes a spatial connection across the two floors. The stairs, facing the the living room, not only spatially link the different parts of the house, but furthermore evolve into a multifunctional furniture. The support structure and the façades of the house are designed in wood materials.
