Plan Description

This modern cabin is ideal as a weekend or vacation chalet, secondary structure, or studio. A screened-in dogtrot serves both as outdoor living space and circulation between the two conditioned ends of the building. Like other designs by the Architect, the long, narrow aspect ratio is designed for best energy performance in summer and winter and works well on a small or narrow lot. Originally designed for site with considerable terrain slope, the foundation can be adjusted to accommodate most sites, while the cantilevered ends reinforce the "floating" architecture. Ample south-facing glazing passively heats the spaces in winter, while the pitch and overhang of the southern awning can be altered in design to optimize summer shade. The exterior rolling barn door can be positioned to shade the dogtrot or either living space. BoxKart's 2x6 exterior framing makes it an ideal candidate either for advanced framing a proven stick framing system that reduces lumber and increases insulation for better energy performance or structural insulated panels (SIPs).

Meet the Designer - Francois Levy

null -
"I design homes for people living lightly on the earth, sustainably and in beauty."

Francois Levy designs buildings that capture the imagination, express regional beauty and a sense of place. His projects reflect their cultural and geographical context, and are accessible and comprehensible to the user rather than obeying a preconceived architectural agenda. Levy is particularly passionate about creating projects that eloquently express how we use and conserve energy and water, and inhabit their site. All his work - whether in architecture, teaching or research - investigates the intersection of design, technology, and sustainability. His architectural projects have attracted regional and national press, including features on HGTV and in magazines such as Dwell, This Old House and Natural Home.

Levy holds a BA in classics and philosophy from St John's College in Santa Fe, and two Masters degrees from The University of Texas at Austin, one in Architecture and the other in Engineering. He has taught digital design and environmental controls courses at UT Austin, UT San Antonio, and St. Edward's University. Levy has presented and lectured widely on CAD and BIM (building information modeling). He is the author of BIM in Small-Scale Sustainable Design (pictured below), published by Wiley. His current areas of research interest are sustainable architecture, BIM, cooling through passive ventilation, and space architecture, on which he has presented at international aerospace conferences.
