Floor Plan
Open kitchen/living with vaulted ceiling · 1 bedroom · office nook · utility closet with W/D · covered entry porch
A pre-engineered 480 sq ft ADU designed for one thing: builder profit. Optimized framing, standard materials, fast build — ready to permit.
ADUs are the fastest-growing segment in residential construction. But most plans waste money on custom details, odd dimensions, and special-order materials.
The Cascade 480 was designed from the lumber yard up. Every dimension is a multiple of 4 feet. Every wall section hits 16" on-center framing. The roof uses standard trusses. The foundation is a simple rectangle slab. No steel beams. No crazy cantilevers. No $400 windows.
The result: a plan set that a framing crew can read in 10 minutes, a materials list that fits on one page, and margins that actually work.
