Hangover House, Modernist building in South Laguna, United States.

Hangover House is a flat-roofed modernist house of concrete and glass built in 1938 on a hilltop above Laguna Beach, with views over the Pacific Ocean and Aliso Canyon. It has three bedrooms, one each for Richard Halliburton, Paul Mooney and architect William Alexander Levy. A 17-foot reinforced-concrete retaining wall, its beams hooked into the bedrock, creates the approach and turnaround terrace.

Richard Halliburton bought the Laguna Beach site after spotting the ridgetop from horseback on the beach in 1930, and William Alexander Levy built the house there in 1938. A road and a 17-foot reinforced-concrete retaining wall went up before construction. Halliburton and Paul Mooney were lost at sea in March 1939, shortly after completion; his parents sold the house at auction in 1941 for $9,000 to the Scott family, who held it until 2004.

The house represents early California modernist design, where concrete and glass work together to bring natural light into every room. Large windows and flat roofs define how this residence looks and functions today.

Hangover House is a private residence at 31172 Ceanothus Drive and is not open to visitors. Its approach and turnaround terrace were cut into the hillside behind a 17-foot-high reinforced-concrete retaining wall, whose beams are anchored back into the bedrock. The house can be seen from the beach and from the ridgeline above Aliso Canyon.

Glass blocks integrated into the gallery walls allow views looking down into Aliso Canyon below, creating an unusual connection between interior and the ravine beneath. This transparent feature sets the building apart from typical cliff-edge residences.
