MainStreet Property Group LLC, in partnership with Grousemont Associates, recently announced the start of construction at Siteline, an eight-story mixed-use building located next to Seattle Center in the Uptown neighborhood. The groundbreaking will kick off in a public ceremony at 9:00 a.m. tomorrow at the project site.

The building is slated to open in summer 2023. Located at 223 Taylor Ave. North in the shadow of the Space Needle, the 334,767-square-foot building features 214 apartment homes, of which 43 units will be priced within Seattle’s affordability program.

The project also includes 43,000 square feet of commercial office space, 6,500 square feet of ground-level retail space, approximately 10,000 square feet of public outdoor space and 274 parking stalls. 

“From the Siteline, residents, visitors and tenants will have a line-of-sight on many of the important landmarks that make up the Seattle Center and South Lake Union areas. That unique outlook is woven into the design of the project and we plan to honor many of the elements that make Seattle and this area unique. When complete, the Siteline will truly be a one-of-a-kind localized experience,” said Kelly Price, MainStreet Property Group president.
