Masters Construction Services: Design-Build Remodeling, Additions & Outdoor Living in Portland

Masters Construction builds architecturally integrated additions, kitchen and bath remodels, finished basements, ADUs, and high-end outdoor living. We work across the Portland and Vancouver metro.

Design, engineering, permitting, and construction sit under one contract. The drawings you approve are the drawings we build. Many homeowners search for a master construction company in Portland to turn a dream home into a finished one; that is us.

Design-build means one team and one contract. We measure the existing house, draw the plans, engineer the structure, price the work, pull the permits and build it.

That removes the usual gap between a plan set and a bid. Cost feedback arrives while the design can still change cheaply, not after the drawings are finished.

A project runs in five phases. A free site walk, then design and 3D visualization, then engineering, permits and fixed pricing, then construction, then walkthrough and aftercare.

We are licensed in both states — Oregon CCB #248237 and Washington — bonded and insured. On the Oregon side we permit through Portland BDS, Lake Oswego, West Linn, Beaverton, Washington County and Clackamas County.

In Washington we work through the City of Vancouver and Clark County. Being licensed on both sides means a Camas or Washougal project runs the same way a Portland one does.

One project lead stays with you from the first call to the final walkthrough. You get a written update every week with photos, schedule and budget status.

Change orders are priced and approved in writing before work starts. Interior projects get dust containment, floor protection and daily cleanup.

Much of our work is in historic and high-end neighborhoods — Lake Oswego, West Linn, Dunthorpe, Irvington, Laurelhurst and Camas. Matching existing architecture matters as much as the new work. See how we work and what projects cost.
