closed

Text description provided by the architects.The architectural firms Terra Capobianco and Galeria Arquitetos are responsible for theCasa Treliça (Truss House) project, a 464 m² building in theAlto de Pinheirosdistrict, São Paulo. Through the rationality of the construction systems, the architecture sought to produce a large space totally integrated into the landscape around the 533.35 m² lot.The constructive solutions, along with other aspects of the project, ensured that Casa Treliça was awarded the Silver certificate by the Green Building Council Brasil, a national reference in sustainable construction. The residence is equipped with photovoltaic panels, installed on the main block and the shed, in addition to a water tank filled with reuse water, intended exclusively for toilets. The house also has automated rainwater irrigation for the garden.Positioned in the ground floor social area, a metal staircase leads to the first floor, where the trellis is revealed in the backlight of the translucent thermoclick material (polycarbonate sheeting). A common room distributes among the four suites. Two of them were designed in a flexible way, initially serving the resident couple, with two bathrooms, two closets, a bedroom, and an intimate room. The first floor of the edicula houses the fitness room and the guest suite.The visual use of the lot is uninterrupted. Less than 1/5 of the first-floor area has opaque fences, which produces a sense of spaciousness - further enhanced by the 3-meter-high ceiling. Thus, the living and dining rooms can be completely opened with sliding glass panels, allowing full integration with the veranda, pool, and garden. A path designed with molded-in-place concrete treads runs through the garden to the leisure area, with a sauna and barbecue grill located under the trellis of the stables.The bedrooms face east and west and have vertical slatted shutters made of autoclaved and carbonized pine, a material that guarantees durability. On the north façade, the thermoclick guarantees thermal resistance, besides the agility of assembly with a self-supporting panel of tongue and groove. The four faces delimit a single rectangular volume of double façade, dismountable and efficient.The implantation of the residence is based on a program of needs to take maximum advantage of the land occupation. The intention was to solve, with few elements, a fast and dry construction, in metallic structure, steel deck slab, and steel frame closing. For this, three metallic trusses were projected: two at the longitudinal ends of the main volume, allowing a 15-meter span, free of supports, in the social area; and the third one in the transversal direction of the total land width, configuring the suspended volume of the shed, with 14 meters of free span.
