The building maximizes its triangular site, coming to a sharp point at the corner.

1 De Haro

San Francisco, California
A Mixed-Use Space for the Creative Process

Located on the triangular site of a former gravel yard, 1 De Haro, a project developed by SKS Partners and designed by Perkins&Will, is San Francisco’s first cross-laminated timber (CLT) building and California’s first multi-story, fully mass timber building. The four-story, 134,000 square foot building blends into its urban surroundings while still making a statement. Designed to evoke a jewel box, its wooden core is wrapped with a glimmering glass curtain wall that illuminates at night. 1 De Haro provides an attractive mix of office and light industrial space that is both sustainable and marketable.

Lobby area features wood detailing and is illuminated by floor to ceiling windows.
The team designed custom moveable sunshades to help keep the building cool.
what makes it cool
1 De Haro is the first mass timber building in San Francisco to use CLT and the first multi-story building of its type in California.
CLT panels are lifted into place and then secured.
Mass Timber

1 De Haro was built much like many podium structures throughout the country, with stacked wood construction on a concrete base. However, 1 De Haro’s wood structure is made of mass timber, a construction technique relatively new to North America. By utilizing cross-laminated timber and glue-laminated timber, 1 De Haro is lighter, more sustainable, quicker to construct, and more beautiful than a steel or concrete building. Wrapped in a simple yet finely detailed curtain wall, the warmth and quality of the exposed wood connects to the building’s purpose of supporting local makers.

The exposed wood creates a sense of warmth throughout the building.
Mass timber makes 1 De Haro lighter, more sustainable, quicker to construct, and more beautiful than a steel or concrete building.
At street level, roll up doors and storefronts bring light manufacturing to the street and surrounding neighborhood.
"The material choice allows aspirations, character, and sustainability to combine holistically to create a built environment that looks and feels good."

Retractable doors open from the lobby to the adjacent plaza and create an indoor-outdoor atmosphere.
Production, Distribution, & Repair (PDR)

PDR is a unique San Francisco zoning designation, designed to strengthen the supply of light industrial buildings. PDR zoning districts do not allow the construction of new office buildings, unless those new buildings also provide one third of their space exclusively for businesses that comply with the PDR designation.

PDR buildings adapt to the needs of creative people and are, by definition, more raw and straightforward spaces. PDR developments like 1 De Haro create opportunities for traditionally siloed industries to become more integrated into the fabric of a neighborhood, helping to blur traditional boundaries and spur innovation.
