Fifteen Twenty-One Second Avenue

The 440-foot tall glass and metal tower contains 143 condominium units across 32 floors, offering views of Elliott Bay and Mount Rainier.

Weber Thompson completed the construction of this residential high-rise in 2008, marking a transition period in Seattle's urban development during the financial crisis.

The building integrates environmental design elements, receiving LEED Silver certification as the first residential tower in Seattle to achieve this standard.

Each residence features floor-to-ceiling windows, private elevator access, and multiple exposures through the building's distinctive angular architecture.

The structure incorporates four vertical glass shards that extend upward, culminating in a 40-foot curvilinear mechanical screen at the crown.
