Metropolitan Park North
South Lake Union's Metropolitan Park North office building includes five levels of office space over six levels of above-grade parking. The project also includes grade-level retail and a basement-level health club with lap pool and spa. The roof steps back at the office floors with a dramatic garden at the top parking level.
A long-span concrete framing system for both the office tower and parking structure uses widely spaced columns to create open office space and excellent parking efficiency. In addition, it reduced structural costs through standardized formwork and no need for transfer beams.
The building is constructed with post-tensioned concrete floors; shear walls around the cores resist seismic loads.
