Sweeney Blocks redevelopment edges toward construction as final permits advance
The long‑anticipated redevelopment of the former Alki Lumber site is entering its final pre‑construction phase, marking the most significant movement on the project since the Sweeney family sold the lumber business in 2021 but retained the land for redevelopment.
City records show that the two‑building mixed‑use project — now branded collectively as the Sweeney Blocks — has cleared its major design hurdles and is awaiting final construction approvals. The eastern building, located at 4406 36th Ave SW, received its land‑use approval late last year, while the western building along Fauntleroy Way SW is in the final stages of technical review.
Together, the projects will replace the century‑old lumberyard with roughly 300+ apartments, 10,000–12,000 square feet of retail, and 150+ underground parking stalls, reshaping a key gateway into the West Seattle Triangle.
