Although it’s just 924 square feet, Maria and Louis Gabriel’s Los Angeles back house, designed by Jason Kerwin of OKB, packs in a lot of program, including a family room on the ground floor and an office and a guest suite upstairs. The siding is by James Hardie and the stairs are painted in Celluloid by Dunn-Edwards.
The Longhouse is clad in Ampelite fiberglass-reinforced polycarbonate sheeting. Per the firm: "The smart gel-coated cladding provides different levels of UV and infrared resistance, and panels with different finishes have been deployed to optimize solar penetration and shading depending on the orientation of each facade and roof plane." This cools temperatures in summer and keeps warmth in winter.
Almost every room in the extension has direct access to the outside so the relationship with the grounds is immediate. In addition, carefully considered windows frame views of the surrounding landscape—especially the large window facing the valley in the first-floor living space. “It’s incredibly joyful to see how the views, smells, and emotion of being in the extension changes throughout the different seasons,” says architect Je Ahn. “It’s very tranquil and a retreat in the true sense of the word.”
