Mirror House in Beverly Hills
The Mirrorhouse is perched in the hills of LA, located in the Trousdale Estates of Beverly Hills with an incredible view extending from Downtown LA to the Pacific Ocean.

The project is an exercise in restraint with a very straightforward goal: to create a simple, rational house that accentuates and amplifies the connection to the exterior – celebrating the unique lifestyle that Los Angeles provides.

Openhouse by XTEN Architecture
The Openhouse is embedded into a narrow and sharply sloping property in the Hollywood Hills, a challenging site that led to the creation of a house that is both integrated into the landscape and open to the city below. Retaining walls are configured to extend the first floor living level into the hillside and to create gardens on two levels. The front, side and rear elevations of the house slide open to erase all boundaries between indoors and out, connecting the spaces to gardens on both levels.
