Last March, WeWork co-founder and former CEO Adam Neumann quietly sold his retreat in the Hamptons, accepting an offer of $1.25 million for a property he’d purchased about seven years earlier for $1.7 million.

Around a month earlier, Neumann listed his 7,880 sq. ft. combination unit in Gramercy Park for $37.5 million; that property, which encompasses a penthouse duplex as well as a substantial chunk of the next lowest floor—and a pair of guest or staff apartments further down in the building—remains for sale.

The third of Neumann’s residential properties to appear this year is this desert contemporary-style in Corte Madera, California. The house’s architecture is gracefully daring, with a series of gently sloping arcs suggesting fluid motion. Stone, steel and glass are featured heavily.

Inside the 10,000 sq. ft. main house, lines curve and arc like windswept desert stone. Open, bright and very warm—desert tones predominate—the interiors are cerebral, hopeful, and a little whimsical. Amenities include a media room, an office, a racquetball court and a master with a private terrace and a fireplace.

Accommodations on the property also include a two-bedroom guesthouse; at around 3,000 sq. ft., it’s a fairly big one. The lot is nearly eleven acres, abundant space for walking paths, a large recreation and pool area, a greenhouse, and a cabana.
