Design the inside before the slab is poured.
We join your architect and builder at the plan stage, so lighting, plumbing, millwork and every finish are resolved before construction pricing.

New construction interior design is the process of selecting and documenting every interior finish, fixture, lighting location and built-in during the planning phase of a custom home, so the builder can price and build it once without change orders. PHX Interior Design provides this service in Phoenix, Scottsdale, Cave Creek, Bozeman, San Francisco, Guadalajara and Zapopan.
