Located in the Pearl District in Portland, Oregon, Block 136 encompasses two buildings on the block, joined by a courtyard. The low-rise is a 75-foot tall mixed-use brick building with office and retail echoing the style of the historic buildings in the neighborhood. The second building is a steel 150-foot tall residential high-rise which reflects the style of the neighborhood to the north.

The residential high-rise tower features 218 apartments and the low-rise office includes retail spaces at ground level. Both buildings share a courtyard and two levels of below grade parking. The high-rise structure, below grade parking, and low-rise up to level 2 are cast-in-place post-tensioned concrete. The office building structure is steel framing with wood joists and plywood floor.
