A long and narrow building sited at the top of a lush green mountain in Costa Rica, this house is a porous three dimensional frame that almost disappears into the landscape. Carefully balancing abundant access to air, light and views with the need for episodes of privacy and enclosure, this house is an attenuated deck that loosely holds a few solid concrete blocks – the bedrooms and a swimming pool. Distant views to the ocean are framed by the teak structure and expansive roof. The strategic positioning of built-in furnishings and a carefully choreographed path through the length of the house promise a dynamic relationship to the site.
