Built on friendship and respect.

Al + Len


Dreyfuss + Blackford Architecture began in the 1950s with two visionary friends who championed transformational design in Northern California. Working together and with a group of exceptional people, they produced a legacy of work that the firm continues to build upon.

Sacramento Municipal Utility District Headquarters


In 1952, a defining moment in Northern California architecture was about to happen. Dreyfuss + Blackford were selected to design the headquarters for the newly established Sacramento Municipal Utility District. SMUD Headquarters was the first significant International Style modernist icon in the Sacramento region. The building incorporated forward-thinking technology and sustainability that is still relevant today.

Nut Tree


Of all Dreyfuss + Blackford’s projects, Nut Tree was its most people-oriented success. Millions of travelers stopped at the Nut Tree complex between San Francisco and Sacramento during its seventy years in business. All in one place you could get a bite to eat, visit outdoor attractions, and make fond memories.

Vogel Chevrolet Showroom


The Vogel Chevrolet Showroom (1959) was a Miesian glass box that received an AIA Central Valley Merit Award.

A groundbreaking modern building in downtown Sacramento, the Vogel Chevrolet Showroom was constructed as an addition to an existing warehouse building on a limited site.

The quality and durability of the building’s materials, design, and detailing ensured that it remained a viable, economical office complex for many years.

San Francisco International Airport (SFO)


SFO’s circular roadways, central garage, and curved terminals are the legacy of Len Blackford’s planning vision.

Dreyfuss & Blackford Architects was involved in the expansion of the San Francisco International Airport (SFO) from 1964 to 1981. Blackford's plan was ahead of it's time, the connection to a rapid transit station, arrived more than twenty years after his aspiration.

CalPERS Headquarters Lincoln Plaza North


CalPERS Headquarters was an instant landmark when it opened in 1987.
