Block 18

  • Seattle, Washington

Completed: 2020

Block 18 is a 17-story high-rise commercial building on a half block of the Denny Triangle neighborhood. Its unique glass facade with staggered recessed sections encase office spaces and a floor-to-ceiling circulation staircase that creates an open, collaborative environment. The multiple pocket roof terraces create the central treehouse effect that connects the various floors.

4EA provided design review of the roofing/waterproofing and enclosure systems for this project. Exposed architectural concrete feature walls add a classy yet professional feel to the space. The prefabricated alley wall assembly was constructed of large-format wall panels. The building also features an on-site daycare center and adjacent rooftop playground accessible to office workers.
