Situated at the border of the bustling South Lake Union and Westlake neighborhoods, Union SLU Apartments helps satisfy the increasing need for local housing while providing easy access to nearby businesses and recreation spaces. The 284-unit project provides tenants with varied and distinctive living and gathering spaces which, combined with the project site’s steep slope, resulted in a complex stacking of the eight-story structure. The project’s location in a Steep Slope Environmentally Critical Area (ECA) made it subject to regulations that would have significantly reduced the size of the building. We helped navigate the design team through an exception process which relaxed restrictions, allowing our client to maximize site use and the number of units. Rather than replacing the 1940s retaining system on site, we worked with the general contractor to develop a sophisticated method of re-using and augmenting what already existed. Salvaged walls combined with new soldier pile shoring resulted in reduced cost and faster construction.  To reduce the required size of the building’s detention tank, our civil designers created a pervious concrete sidewalk along Dexter Avenue combined with rooftop planters and P-patches help control stormwater runoff.
