Columbia Building by Skylab Architecture


The Columbia Building supports the City of Portland’s Bureau of Environmental Services. Housing workspace, a visitor reception area, and public meeting spaces, the 11,640-square-foot building not only supports the engineering department of the wastewater treatment facility but also functions as an immersive educational experience, all integrated within a sustainable landscape.

The new single-story building features seven folded cast-in-place concrete roof forms that channel stormwater through a planted roof, which drains along the berms into a visible collection system that leads to the Columbia River. The project accomplished three unique objectives in one single campus site: the creation of a vibrant and efficient workspace; clean on-site stormwater filtration; and a dynamic building that stimulates conversation about the health of the region’s watershed and rivers.
