Garden House 096
BAILORULL, Manuel Bailo i Esteve, Rosa Rull i Bertran
The house is planned for a steeply sloping plot of land on a developed hillside on the outskirts of Igualada. The main direction of the plot is west-east, with the pedestrian and vehicular access at the top (to the east). The views are magnificent. Mobility, due to the topography, is complicated. Both factors determine the design of the house. In effect, the house can be understood as the constructive translation of a descending pedestrian route in three sections, from the level of the road to the wooded area that is preserved in the unbuilt part of the plot. This route, which is possible via the roof, allows one to enjoy the views along the way and, at the end, the entrance to the house is through the same hallway that is accessed from the car park. It is therefore a walkable roof despite being sloped. From the hallway to the master bedroom, located just below it, the privacy of the living areas increases as the height decreases. The living room is located in the second section of this route, providing it with the most impressive views. Structurally, the house functions in its entirety as a bent tube in which the two ends are embedded in the ground and the rest is cantilevered. Specifically, it is a tube made of metal latticework. This latticework is designed to be externally clad with perfectly reflective stainless steel panels. The character of the holes made in the panels contributes to the constructive-programmatic integration of the whole. CONSTRUCTION SYSTEMS The Garden House 096 Project is materially developed from two fundamental construction systems: structure and façade. Both have definitively influenced the final form of the building; that is to say, we can affirm that the final formal result responds absolutely to the structural and constructional needs. - Structure The shape of the space designed to adapt to the slope, the regulations and the views, gives shape to the proposed structure: a box girder that rotates on itself, developed by means of a metal bar structure, anchored to the ground at the upper end and supported on the ground by two pillars at the other end. Apart from the defined structure, the work is built with foundations and retaining walls with reinforced concrete in situ, ceilings above and below the box girder with composite metal decking and a layer of reinforced concrete compression. The rest of the work is dry construction. - Prefabricated Façade As for the façade, a prefabricated one is proposed consisting of the following construction elements: Supply and assembly of a multilayer opaque façade mounted on site, consisting of: external skin in horizontal Formawall 1000 panels, in 1,000 mm wide modules formed by two sheets of micro-galvanised steel, 0.8 mm thick, suitably shaped by injection moulding, forming a total thickness of 50 mm. The finish on the visible exterior face is Kynarcolor, the finish on the exterior face is standard colour embossed polychrome, with a coefficient K = 0.38 Kcal/m2/ºC. The joints between panels are sealed on both sides and are completely watertight. Inner skin formed by plasterboard soffit cladding on galvanised steel sheet framing with profiles between 75 and 85 mm wide, placed every 40 cm, insulation with semi-rigid glass wool (MW) boards 50 mm thick >=1.45 m2K/W, covered with two mechanically fixed 13 mm thick laminated plasterboards. Two boards are used to obtain better thermal inertia. All openings, side jambs, upper and lower finishes are finished with ‘alucobond’ multilayer aluminium sheet, adapting to the different shapes.2004 - 2006
