Located on one of the last remaining infill sites in historic downtown Boulder, 909 Walnut is in the heart of historic masonry, calling into question the solidity and opacity of the surrounding built context.
The building design respects and reinforces the historic nature of downtown while looking to the future with advanced technological systems. The modern facade enters into dialogue with the past through Its proportion, color, texture, and materiality. The design subverts the notion of private and public space. The street level was designed for a restaurant and the two upper levels as speculative offices. The goal was an exemplary building, including use of healthy building standards, and daylighting of each primary space, while maximizing allowable buildable area.
There are two types of layering that define the building sequence from the street edge inward. The first is the programmatic layering of accessible open space: outdoor seating at the street and upper levels and the lobby with the public space of the street. Traditionally private spaces like conference rooms hang in glass boxes open to the public lobby. The second, the highly articulated layering of the facade: structure, skin, planters, and shading devices articulate how the building is made while reinforcing the gradual weaving of public urban space, public building space, and the more private office spaces within.
