Over 70,000 new housing units are forecast to come online within Seattle city limits over the next 20 years. This rapid growth will be a major force shaping our public space. Located along the Republican Street commercial corridor and 8th Avenue, a bustling residential street, the 8th & Republican MixedUse Development balances public and private interests. A redevelopment of a half-block in Seattle’s emerging South Lake Union neighborhood, the new complex includes 211 apartments, a photographic equipment showroom for a longstanding family-fun camera retailer and a small neighborhood café on a pedestrian-oriented street.

Geological and quarry forms were the inspiration to shape the building’s bulk around a generous neighborhood green space, putting on-site stormwater infrastructure on display from the sidewalk. The Megastoop, an elevated public walkway, traverses a large bio-retention rain garden through a grove of trees, while the eight-story post-tensioned concrete building recedes. Conceptually, the building forms the backdrop for a green pocket park similar to the Cascade Mountains rising behind green foothills.

Setting the building back from the street at mid-block provides a generous public courtyard, the backdrop for a well-loved neighborhood café and patio with a participatory water feature. This big move forming public space enables the building façades to remain simple and cost-effective while positively impacting the public realm, foregoing more expensive façade modulation typically required by Seattle’s Design Review Board.

Inside, a two-story lobby features a common table, social mailbox pylons, a gathering lounge for entertaining and flexible workspace designed to nurture community. The Work Yard fronting the alley provides a covered courtyard where residents can enjoy the benefits of a single-family backyard, encouraging activation of the alley space. On the roof, a sunset deck with terraced-wood seating frames views to Queen   nne, Gasworks Park and Saint Mark’s Cathedral.

Designing with Intention

The 8th & Republican Mixed-Use Development holds a strong corner along Republican Street, forming a primary gateway for vehicular traffic entering South Lake Union from the new State Route 99 tunnel to the west. The strong corner also forms a northern terminus for the 8thAvenue pedestrian-focused residential street as it transitions to an institutional and commercial zone north of the site.

Type l post-tensioned concrete was chosen for its reduced structural depth, enabling the addition of an extra floor and 29 additional apartments. Between concrete slabs, exterior non-bearing walls are framed in wood in lieu of light-gauge metal to reduce thermal bridging and the need for

expensive exterior insulation to exceed energy code requirements. Large 6-by-10-foot balconies extend into the courtyard space, offering a view over the courtyard and an expanded offering of unit types.
