The agricultural context on the one hand and a vast area of residential expansion on the other, suggested an imposing architecture, well integrated into the landscape compared to local architectural models. The volume of the model taken as a reference is the archetype of Alsatian architecture which, repeated in several modules, makes it possible to obtain a variable and more suited building for public use rather than private use.
The strongest sign is the roof, which brings together all the functions under a single architectural element, punctuated on the succession of the different spans and facade. The site characteristics prompted us to design a single building which, thanks to the concentration of all the functions of phase 1, allows real economic savings, both in terms of site costs and operating costs.
The building, located to North in a parallel position to the lot limit, creates a functional and large internal service yard, always keeping an ideal distance from the town.This type of implantation allows a total absence of temporary areas. This optimization also allowed us to think about the future, leaving the possibility of placing a massing in the South for phase 2, similar in architectural writing, but not necessarily in form.
The proposal defines a strong and simple architecture, a building of an industrial character mitigated by the logic of the pre-existing sloping roofs. This concept ideasuggested two very different facades.The north facade benefits from constant indirect light reaching through a translucent material such as polycarbonate; very efficient material from a thermal and acoustic point of view, soft and domestic in relation to the surrounding context. The facade facing south, on the opposite, is compact and majestic, thanks to a studied integration of technical elements such as the numerous sectional doors and the porch roof, concedes a more expressive and communicative image with the exterior of the landscape. This porch roof, developed by sliding 3 meters from the south facade inwards, gives continuity to the front and provides shelter to all workers during the most arduous period.
In this way the proposed architectural solution avoids the industrial aspect of the building linked to its function and responds in a simple way to the program, transforming, through a careful research and design, the numerous details into friendly solutions with ordinary materials.
The project defines the construction of the building with low consumption, obtained either by the design of the envelope and the technical equipment. The materials chosen, such as wood on the facade, are ecological and available in the surrounding area. The control of solar exposure is obtained by fixed protections, such as sunshades and porch roof; and the ventilation is guaranteed by a double-flow mechanical ventilation system. The domestic hot water supply is integrated from a set of glazed solar collectors placed on the roof. Lastly, the costs for watering green spaces is contained by making a buried water collection tank.
