A Silicon Valley estate has been offered on the open market for $19.4 million. The property is the home of former Yahoo CEO Tim Koogle. It was designed by John Funk, a noted modernist architect who skyrocketed to fame in the 1940’s.

Funk was an early advocate of placing modernist sensibilities in a context of naturalism. His designs are informed by a progressive ideal of community, and interplay between human order and the natural world. His ideals are expressed in a heavy use of wood and natural stone, which soften the stridency of high modern residential architecture.

Koogle’s house dates to the middle of the 1950’s, and has been renovated with respect for Funk’s original vision. It isn’t a Case Study house, but easily could have been; the exterior is defined by a sense of transparency, emphasis on the incorporation of landscape into the living spaces, use of simple materials, and a bright optimism. The home’s size is right in there for a Case Study, too, measuring about 5,450 square feet, with four bedrooms and 4.5 baths throughout.

The home’s interior architecture and design is strikingly beautiful, and understated; throughout the main living spaces, yellows are presented as a means of enhancing, and segueing into, a marvelous collection of natural wood textures and tones, as well similarly colored natural stone and concrete.

The exterior of the property is dazzling—over twelve acres of grounds, with flower and vegetable gardens, meadowland, raised planters, orchard, outdoor fireplace, walking paths, a pool and sunlounge, and a guest house.

Koogle, the first CEO brought in to helm Yahoo!, spent five years at the company, leaving in 2001 to eventually found Serendipity Land Holdings and The Koogle Foundation.
