Planning a home addition in Bethany, Oregon? If you have been searching for home additions near me, you have found a Bethany-area design-build team that handles structure, permitting, and finish work under one roof. An addition adds the space your family has outgrown, but the work is structural: foundations, framing, rooflines, and tie-ins to existing systems. Done well, it looks like it was always part of the house.
Bethany lots vary, from North Bethany’s tighter newer-construction parcels to larger established lots near Oak Hills. Setbacks, lot coverage, and easements are set by Washington County, and they shape what is possible before design even begins.
We design additions that match your home’s proportions and finishes, then build them to blend in, not bolt on.
Home additions in the Bethany area typically run $60,000 to $300,000+, or roughly $300 to $600 per square foot, depending on whether you build out, up, or add a full suite with plumbing.
A well-matched addition adds both living space and resale value, and in Bethany’s competitive market it is often more practical than trying to buy a larger home in the same neighborhood.

The difference between a great addition and an obvious one is in the details: matching the roof pitch, the siding, the window proportions, and the trim so the new space reads as original.
Before design, we check Washington County setbacks, lot coverage, and easements for your specific Bethany parcel, so the plan is buildable from day one rather than redrawn after a permit denial.
Whether you are adding a primary suite, a great room, or an in-law suite, we engineer the structure properly and tie new systems cleanly into the existing home.
Woodland Construction Group · 18 Years Experience · Serving Bethany & Washington County
We design and build room and second-story additions across Bethany and the Portland metro, matching existing architecture and handling the structural engineering and Washington County permitting under one contract.
A well-matched addition in Bethany can add living space for less than the cost of moving up in the same neighborhood, while raising both daily comfort and resale value.
Most Bethany additions fall into one of these types. Each one is engineered to match your home and meet Washington County code.
Building out to add a family room, office, bedroom, or sunroom, with the foundation and roofline matched to the existing home.
Building up to add bedrooms or a primary suite when the lot is tight, with structural reinforcement of the floor below.
A new owner’s retreat with a spa bath and walk-in closet, designed as a private wing of the home.
Expanding the kitchen, dining, or living area outward to open up the main level for how families gather.
An attached suite with its own bath, and sometimes a kitchenette, for aging parents or returning family.
Foundation, framing, and roof tie-ins engineered so the addition blends seamlessly inside and out.
One team, one contract, from the first measurement to the final walkthrough. Here is exactly how a Bethany project moves from idea to finished space.
We start with an in-depth conversation about your vision, needs, and budget, then visit your Bethany home to assess the space and take measurements. This complimentary consult covers feasibility, layout ideas, and realistic investment ranges for the Washington County market.
Our in-house design team builds detailed 3D renderings and floor plans, presents multiple layouts, and refines the design with your feedback. Material boards show real samples so every decision is informed before a single wall moves.
We guide you through finishes and fixtures, drawing on established relationships with premium Portland-area suppliers. Showroom visits let you see and test selections, with guidance on durability and how each material performs in Oregon’s wet climate.
We pull every Washington County permit, order long-lead materials, and set up containment and site protection before work begins. Handling the county paperwork ourselves is what keeps the schedule honest.
Licensed plumbers and electricians handle supply, drainage, wiring, and ventilation, framing and structural work go in, and we coordinate every Washington County inspection along the way so nothing stalls.
Surfaces, cabinetry, countertops, fixtures, lighting, trim, and paint are completed with precise, clean detail until every surface is pristine and ready to use.
We walk the finished space with you, demonstrate how everything works, and hand over maintenance guidance and warranty documentation. The project is not complete until you are fully satisfied, backed by our 1-year craftsmanship warranty.

Most Bethany additions take 3 to 7 months depending on size and complexity. Design, structural engineering, and Washington County permitting take time on the front end. A simple room addition is faster than a second story or a full suite. We give you a phase-by-phase schedule before construction.
Additions in Bethany typically run $60,000 to $300,000+, or about $300 to $600 per square foot. Building up, adding plumbing, or finishing a full suite raises the cost. We provide a detailed, itemized estimate during design.
Yes. Because Bethany is unincorporated Washington County, additions are governed by county setbacks, lot coverage, and permitting. We check your specific parcel’s limits before design and handle every permit and inspection, so the plan is buildable from the start.
It depends on your lot, your budget, and what you are adding. Building out is simpler when you have the land; building up preserves yard space on tighter North Bethany lots but requires reinforcing the floor below. We will recommend the right approach for your home at the consultation.
That is the goal of a good addition. We match roof pitch, siding, window proportions, and trim so the new space reads as original. The structural tie-ins are engineered so it performs as one continuous house, not a bolt-on.
Yes. We build attached suites with a private bedroom and bath, and a kitchenette where code and your goals allow. We design them for accessibility and privacy, and handle the Washington County permitting throughout.
