In November 2023, the general contractor Turner Construction filed a lien on the property. Stumptown Coffee Roasters opened a cafe on the ground floor of 11W in April 2024. 11 West sits kitty corner across SW Washington Street from Twelve West, which was developed by the same developer and designed by the same architecture firm.
