This 10,000-square-foot addition to NAC|Architecture’s Spokane office expands studio, administrative and support space to accommodate the firm’s ongoing growth. The addition houses 35 work stations as well as a large multi-use room for office and other professional functions. The building is physically connected to NAC|Architecture’s original historic brick building in what was previously a nine-car surface parking lot. The building site is small, sandwiched between the historic building and an adjacent surface parking lot. While the original building’s historic nature – with its load-bearing masonry walls, punched opening, and tile mansard roof – might have suggested a historic design solution for the addition, the character of other surrounding buildings is more diverse. Nearby historic buildings include Lady of Lourdes, the Masonic Center and the West Coast Life Insurance building. Adjacent to NAC|Architecture’s original building is the revitalized Riverside Court townhouse with its plazas, fountains and gardens, as well as historic masonry apartment buildings. The Spokesman-Review’s stucco truck-fleet garage (the old Greyhound bus station), in an art-deco style, is directly southeast of the site. Other buildings in the neighborhood have a more modern appearance. Designed as a modern urban-infill gem, the addition plays a significant role in the continuing revitalization of downtown Spokane. While the design of the addition is a vivid departure from that of NAC|Architecture’s existing building, subtle elements were employed to unite the two structures: horizontal lines, a similar pallet of colors, and complementary building materials. The colors of the addition’s copper wall panels and sandstone were chosen for their similarity to the colors of the existing building’s brick and cast stone.The building form, which is predominantly a cantilevered glass studio extending over a stone wall base with a concrete stair tower anchoring the corner, speaks to the variety of the architectural styles in the neighborhood, respecting the historical surrounding but clearly stating that it is from a different era in the continuum of time. Materials selected also reflect those of the neighborhood, including the copper panels that transition to the neighboring structures with the copper roof of the Lady of Lourdes Cathedral dominating the skyline of the neighborhood.Simple landscaping and street trees have been added along the east street façade at the cantilevered studio space, continuing the landscaping palette of the Riverside Court townhouses and softening the pedestrian experience.A simple gesture of a new stair to the elevated surface parking lot to the south enhances pedestrian access to and around the site. The stair is well-lit, has adjacent planting beds, and is used often by residents in the neighborhood.Sustainability is a core value of the building owners and occupants. LEED Silver certification is anticipated for the USGBC-registered building. Sustainable features include: maximized daylight opportunities with the low-e glass façade, motorized roll-down shades and translucent skylights; energy-efficient lighting systems with integrated daylight sensors and dimmable ballasts; ultra-high-efficiency water fixtures and irrigation systems; and an efficient displacement HVAC system that increases indoor air quality.
