Yes. This space is located within a carefully restored historic building dating back to the early 1900s. Originally part of the area’s early commercial fabric, the structure retains its signature brick exterior and exposed timber details while being thoughtfully updated for modern use. The result is a workspace that honors its architectural roots while offering the functionality and design expected today.
