Multi-disciplinary design firm Mackenzie this summer celebrated the 20th anniversary of its Seattle office.

The firm, which also has offices in Portland and Vancouver, set up shop in the Emerald City in the Logan Building in 2004. Today, that downtown property at 500 Union Street remains home but now to a vastly expanded enterprise.

The office has grown from five staff members to nearly 30 professionals. The first iteration of the Seattle office offered architecture and interiors services. Professions have since grown to also include civil engineering, structural engineering, and land use planning.
