Sited on the edge of a large parcel near the Pacific Ocean, the Ark House is a small studio building on the site of Richard Neutra’s iconic 1934 Sten-Frenke House. The design and massing of the structure, which includes a private office suite and guest quarters, is designed in response to the conditions of the main building. The curved façade of the new structure mirrors and doubles the distinct curved volume of the sun-room in the main house: a signature geometric form in Neutra’s early work in North America.
