High-End Design, World-Class Green
Oakland builder’s plan for a sustainable family home evolves into one of the greenest homes in the country
Bookmark and Share



The Margarido House, as it’s known, is the only LEED Platinum home north of Monterey, Calif. It’s also GreenPoint certified by BuildItGreen.org. A NanaWall folding door (seen in inset) expands living space to the backyard where access to the rooftop garden is gained via an outside staircase.

A roof garden is one of the many green features of this home in Oakland Hills, Calif. The garden is surrounded on two sides by a deck on which to relax and enjoy the unobstructed view of San Francisco Bay.
The living room space is separate but part of an open floor plan flexible enough to encourage conversation yet allow privacy as well.
Concrete countertops and Energy Star Whirlpool appliances are just a few of the many products that make this home sustainable enough to earn both LEED Platinum and GreenPoint certification.
Plenty of natural light throughout the Margarido House welcomes the residents and guests alike into spaces like the master bath.
The outdoor living space utilizes the hillside it’s sunken into to create a surprisingly private area in which to relax and entertain.
