Recessed into the crest of the hill and oriented visually toward the access road, this small government annex building is presented from across a broad sweep of lawn to enhance an image of importance. 
To increase the impression of size, the building's longitudinal axis is stretched in plan and further extended with an auto canopy. Site retaining walls, pools and portico are all designed as extensions of the architectural construction system to meld building and site into a single sculptural composition.  
Responding to site conditions and client's desire for operational economies through energy conservation techniques, the building is recessed into the hillside to utilize earth contact advantages, in turn establishing an architectural expression reinforcing the public facade.  The building's roof is terraced to create tiers of clerestory windows taking advantage of diffuse northerly light and providing virtually continuous uniform daylighting throughout building during all seasons. Artificial lighting is controlled by sensors that turn on lights only as needed with 10% annual usage anticipated. Building design is expressive of the construction system which is based upon a modular repetitive assembly of prefabricated structural, mechanical and electrical components. 
Walls of concrete grow out of the site to reinforce earth contact character. The roof system is precast concrete with perforated trusses to form clerestory windows and provide a flexible, column free, daylight interior volume. Each bay is served by separate rooftop heat pumps expressed on the exterior. On the interior, exposed duct-lighting elements provide further system definition, and building detail.
