The House ARM, a 1,751 square-foot home designed by OOIIO Arquitectura and situated in Toledo, Spain (some 4,000 miles — give or take — from that other one in Ohio), is a functional, cost-effective one level home that uses geometric extrusions and sections to gather as much natural sun light as possible.
The house was built with structural walls due to the single-story design plan, which saved time and money during the construction process, and thanks to the thickness of those walls, they contribute to save energy and improve the home’s sustainability. The structural walls are formed from extruding two sections, resulting in two long parallel pieces that begin from the street façade and reach the yard that don´t touch each other , yet they are connected by some flat roofs that cover certain utility spaces (i.e., the hall, the laundry, the parking, etc.).
For optimal passive energy performance, the home has ceramic ventilated double façades, with exterior isolation, and the windows are opened in areas of the home where the sun won’t heat up as much. The interior cooling and heating is performed by a special radiating floor, and both passive and active energetic systems assist in saving money and energy every day, making the home relatively inexpensive to live in.
