Commercial Office Conversion

The Office on
15th Avenue

A former bank transformed into an office for an architecture and design firm.

In 2017, our team was fortunate to be able to design an event space and home for Board & Vellum on Capitol Hill. Spreading over two floors, the primary design goal was to capture the personal feel of our work and translate that into an office space: the intersection of commercial and residential design.

Turning a formerly dark and crowded bank into a bright and open office called for tearing down walls, carefully organizing the floor plan, and creating a layered lighting plan. The main floor is anchored by a whitewashed feature wall, which divides our more public spaces – such as the conference rooms, gallery, and kitchen – from the more private desk space.

The workspaces are all equally-sized, with powered standing desks, and communal meeting tables within each pod. The partial-height walls allow for private conversations while still promoting an open-office feeling.

Downstairs, the “Below Grade” event space allows for flexibility with a secondary kitchen, employee lounge, and a classroom space. Support spaces include four bathrooms, a shower for bike commuters, a bike room, and comfortable, personalized kitchens.

In 2026, we made the decision to move our office to the Smith Tower in Seattle’s Pioneer Square neighborhood. You can check out the Smith Tower Office in our portfolio and learn more about our move to Pioneer Square on the blog!
