2281 Glisan is a mixed-use building located in an historic retail and residential neighborhood in Portland, Oregon. The 14,000 s.f. structure incorporates office and retail spaces on the lower three floors with a multi-level private residence and roof garden. Set behind a veil of existing street trees, a skin of glass, slate, stainless-steel mesh and stone tile wraps the structural frame and extends to the limits of the zoning volume. The composition of surfaces - solid, screened and transparent - presents a unified exterior expression while negotiating diverse interior functions.
