Midcentury time capsule by Pierre Koenig on the market for the first time since 1960

Now being offered in an off-market sale is one of Case Study architect Pierre Koenig’s earliest works.

Located down the road from Koenig’s Seidel Residence in bucolic Mandeville Canyon, the home was built in 1951 and has not changed hands since 1960. It has, however, changed form somewhat, with subsequent additions and updates performed by Dutch-born architect Josef van der Kar.

Measuring 2,821 square feet, the modernist pavilion is reminiscent of Koenig’s Case Study houses, with a steel framework and expanses of floor-to-ceiling glass. The four-bedroom, three-bath time capsule’s features also include tongue-and-groove beamed ceilings, clerestory windows, wood-paneled walls, period sconces, and a stacked-stone fireplace.

The property occupies a .63-acre lot with landscaping by Koichi Kawana, designer of the Japanese Friendship Garden in San Diego’s Balboa Park.

Per the listing, asking price is “upon request.”
