Founded by the late Bay Area architect William Turnbull (who worked with Charles Moore on the iconic Sea Ranch development on the Pacific Coast), San Francisco firm Turnbull Griffin Haesloop, under the leadership of partners Mary Griffin, Eric Haesloop, and Stefan Hastrup, continues to specialize in simple, vernacular structures "rooted in the environment, with particular attention paid to topography, microclimate, vegetation, and solar orientation," according to the firm.
