TreeHouse
Tucked into the wooded hillside on Veteran's Parkway next to the Oregon Health & Sciences University, the irregular octagon
shape is aptly named The TreeHouse. Forward architecture, contemporary interiors, a rooftop retreat, an onsite cafe, park like
surroundings and trails. All with instant access to OHSU and just minutes to the South Waterfront and downtown Portland.
TreeHouse
With 1033 cubic yards and 43,000 SF, the TreeHouse may be on the
smaller side, but was big on challenges. The building includes 71 modern apartments.
TreeHouse
Exposed walls and columns had their own challenges due to the design maximizing the
space and keeping a minimum distance between the loadbearing columns and the outside walls.
TreeHouse
South east facet of the octagon, from the parking garage, features a sloping retaining wall and exposed column.

Constructed next to an operating parking garage for OHSU,
concrete placement was difficult at the farthest points of the project.

Deep storm water planter foundation had to be cast and buried before
building foundation to avoid undercutting the ground level slab on grade.
TreeHouse
West facet elevation shows exposed columns and architectural
walls that received direct storefront mounting to the top of walls.
