Mid-Century Modern Prefab Addition

The modular structure' steel-based construction technique is similar to the method implemented by California-based architect Pierre Koenig in the '50s for the case study house #22. Large floor-to-ceiling windows connect the interiors with their environment and allow tight quarter to feel more spacious. The argon, double-paned windows maximize natural light– and energy-efficiency.

On the 48 square-foot cantilevered deck, a blue bench makes a colorful statement. Recessed LED lighting illuminates the space after dark, while weather-resistant gypsum board clad beneath the cantilevered overhang protects against inclimate weather.

A series of simplified metal cables serve as porch railings. Held in place with basic fasteners, the sensible approach suits the structure’s modern ethos. "We chose the cable-style railing to maintain the openness of the deck and promote air circulation," says Celestino.

The "Think Tank's" corrugated metal Galvalum cladding is locally purchased. Held into place with mechanical fasteners, the siding is durable, inexpensive, and easy-to-clean.
