Save $100K+* Building a Custom Home
Administrative support and organized project information for homeowners who direct their own build—with the potential to save $100K+.
Administrative support for owner-builders
You direct the build. We organize the paperwork and information.
Traditional builders often add substantial overhead and markup. CMGWA offers qualified Washington homeowners a different path: you remain the owner-builder and retain full control while we provide administrative support, recordkeeping systems, and an organized workspace.
CMGWA does not act as your general contractor, direct or supervise construction, select contractors, approve work, or make construction decisions. The homeowner is responsible for the project and all decisions from design through occupancy.

Featured custom home
A perfectly balanced 2,400 sq. ft. ranch.
Four to five bedrooms, 3½ to 4½ bathrooms, upgraded finishes and a generous outdoor-living connection—all customizable for your property through our owner/builder program.
Owner-builder projects we’ve supported
Real Washington projects. Individual visions.
