The second of two side-by-side Harry Gesner-designed beachfront houses in Malibu to appear for sale on the open market this spring is Sandcastle. The home popped up for sale about a month ago, preceding the listing of its sibling, the Wave House, by a few weeks.

The 1974-built residence, which is currently listed with an asking price of $27.5 million, is the later of Gesner’s self-designed (and apparently largely self-constructed) homes in this private corner of the Southern California coast. Its architecture appears to exhibit futurism, along with a certain degree of coastal homage; in front, it shows off a broad arc of glass to the Pacific horizon, while its back section — where the bedrooms are situated — resembles a lighthouse. But overall it appears to be one of the more remarkably freewheeling examples of early-1970s contemporary home design to survive in this area. Thorens and Whole Earth Catalog not included with sale.

The home features weathered timber outside, and a great deal of reclaimed wood inside, along with the hewn buttresses that support the ceiling of the circular section. All told, it earns its title, appearing to have put driftwood artfully to architectural use. Also featured prominently in the main living area are reclaimed stained glass windows, plank bookshelves, a brick fireplace, and an interior greenhouse.

The house contains six bedrooms and eight baths across its 6,451 sq. ft. of interior living area. The master is located in the back section, and features a brick fireplace and a private sitting area; one of those prominent eyebrow-shaped windows opens to a splendid window seat slash reading nook.

Sandcastle sits on a .73-acre lot, which is filled out with a guest house (designed in kind) and a large plateau of ocean side lawn. Taken together with the Wave House, itself poised on a .7-acre lot, the two properties represent a remarkable opportunity to own an architecturally significant compound in one of the more enduring corners of Malibu.
