One of modernism’s most iconic houses, Case Study House 21 (Bailey House) by Pierre Koenig, is now on sale. The two-bed/two-bath Hollywood Hills landmark has been touted as among the finest of Arts & Architecture Magazine’s Case Study Houses, and one of the program’s few truly experimental projects to explore groundbreaking design and materials.

In this early-career exploration, Koenig used a constrained set of industrial materials—primarily steel and glass—to execute a pure expression of his design approach. His philosophy of functionality and honesty in aesthetics manifests in a structure that appears simple but contains complexity in plan and organization.

The design emphasizes harmony of materials and balance between interior and exterior through the use of terraces, water, glazing, and skylights. A 60-foot reflecting pool frames the undulating steel facade on the east and another pool traces the covered carport. Interlocking steel decking on the roof and an all-glass north wall add drama to the main entry, drawing visitors in, while the southern wall’s sliding glass doors extend the living area into the exterior terrace.

Views of the expansive and carefully considered landscaping permeate the house. In the core of the house is a courtyard and the bathrooms; the bedrooms are also connected to the exterior via sliding glass doors.

Built in 1958, Case Study House 21 underwent a restoration by Koenig to his original intent and design in 1998, including the addition of updated appliances and cabinetry. The house was last sold in an auction in December 2006 for an estimated $2.5 million – $3.5 million.

Update [Nov. 7, 2016]: A previous headline for this article suggested that the house is currently on the market for $3 million – this was based on the estimated sale price from its last sale in 2006. Instead, the listing is currently on the market as “Price Upon Request.”
