Text description provided by the architects. A shelter for the weekends. That is the proposal of this house located in São Francisco de Paula, mountain region of Rio Grande do Sul, 100 km away from Porto Alegre. Placed in the center of the area, surrounded by the forest, the house overcome a soft declivity, resting itself on a reinforced concrete slab raised from the ground in order not to intervene with the natural profile and to exempt it of the ascending humidity.
Its volumetry is simple: two rectangular boxes of different textures intercepted. The bigger one, covered with metallic wavy tile, shelter the intimate sector with two bedroom suits in opposite sides. The second box, in wood and more transparent, crosses the metallic pavilion configuring the social and service sector. From this crossing, a wood deck overhang over the vegetation, crossing the main body of the house exerting the access function, hall of distribution and terrace.
The house was thought from a simple logic structural, with modules of 1.20 x 1.20m arranged by steel frame upon a concrete base. The composition of the walls is proper of the constructive system: a sandwich formed by drywall, rockwool, osb and permeable membrane isolating the structure of the humidity.
Only in the wood box the interior cover is the same of the exterior. Complementing the structure, a concrete block box, half-embedded, retreat in relation to the base, conforms the foundations sheltering in the biggest unevenness a small deposit.
The project looked for to answer the necessities of the program desiring to delimit the constructed space, without merging or camouflaging themselves, but assuming the landscape without competing with it.
The option to construct in steel frame occurred by two main aspects: agility in the construction, falling the working time in situ, and the control over the constructive process therefore executing the metallic structure in a shed in Porto Alegre, 100 km of the house area, made possible a daily supervision of the team technique supported for an equipped structure of the place.
At the end of two weeks, all modules of walls and segments in frame were being carried to the final assembly in the area. That stage took more 8 weeks for conclusion of the services.
For accomplishment of the project and execution of the shelter the partnership with the supplying companies was essential. On the definition of the constructive system, we count on the experience of Placo Center and Formac. Second, company of Chilean origin that acts in Brazil since 2005, supplied all the steel frame and system of sliding doors beyond calculating and designing the structure.
