Graham Street Lofts was constructed using PerformWall insulated concrete forms. The walls are 10 inches thick and made of recycled polystyrene and cement. This type of construction is the best solution for the climate of the Pacific Northwest. It is mold, mildew and rot resistant and has a four hour fire rating and exceptional seismic strength.
The walls provide a breathable shell with an R-30 insulation factor, which greatly reduces outside noise. The shell coupled with a hydronic radiant heating system can significantly reduce the energy use of any home.
All finished within Graham Street Lofts were selected for their sustainability and durability. The cabinets have plywood boxes, solid maple drawers and lyptus veneer faces; there is no particle board or melamine. The interior doors are wood veneer and the windows and French doors are fiberglass.
The site upon with the community was constructed is also sustainable. Storm water is disposed of on-site. Roof runoff goes into dry wells underneath the parking lot. Parking lot runoff goes to bio-swales at the south edge of the property for filtration before soaking into the ground.
