Building a new house is a lot of decisions. We help turn ideas into permit-ready plans. We do residential drafting and permitting, not architecture. When structural engineering is needed, it goes through Dow Engineering PLLC (https://dowengineeringpllc.com). We work in Pierce and King County: Sumner, Puyallup, Bonney Lake, Tacoma, and Auburn.
Site plan; floor plans; elevations and roof plan; sections; window and door schedules; energy code notes that match your energy credits; and structural engineering when needed through Dow Engineering PLLC.
Start with the lot. Then a rough layout, refinement, and the permit set. After that we submit and respond to the building department. Questions about the permit side? See our Permit Help page. Building it yourself? See our Consulting page.
