Trillium House
Trillium House is a 42 unit affordable family housing project on the rural Oregon Coast, in the city of Warrenton. It is new model for multi-family housing in rural areas: higher quality, more accessible, more secure, and more sustainable. Trillium employs Walsh Construction’s Cost-Efficient Design and Construction (CEDC) that optimizes structural framing, efficient building plans (net to gross area >80%), efficient dwelling unit plans (narrow “aspect ratio”), compact plumbing layouts, standardized & repeated typical elements, and maximized prefabrication to reduce project cost and construction time. Trillium was constructed in 11 months, down from a usual 14 months for a comparable project.
Trillium's efficiencies influenced the design of the Emmons ImHomeToo modular standardized multi-family dwelling units.
