Double-House is composed of two side-by-side sliding rectangular volumes, each with a unique material and spatial character. As the volumes slide past one another and adapt to the conditions of a given site, they produce a series of spaces with increasing levels of privacy, including two outdoor porches along the front and rear. The soaring nature of the curved roofline marks the moment of entry off the front porch. The façade embodies the ADU’s repetitive duality through its use of inverted rooflines, which are optimized for solar energy and water collection. This duality is further emphasized through the material juxtaposition of vertical and horizontal elements on each volume. Inside, programmatic shifts divide the two rectangular volumes into three zones: (1) an entry threshold, (2) a shared living space, and (3) a private sleeping area. The ADU’s rooflines create a layered experience that lends an intimate quality to the shared living, dining, and kitchen area.
