Custom Homes
Custom Homes Built From the Ground Up. Built For You.
Building a custom home is the most personal project you will ever undertake. From the orientation of the windows to the width of the hallways, every decision is yours. We translate your vision into precise, permit-ready construction documents — so your builder can break ground with confidence and your local jurisdiction can approve without delays.
Serving Woodburn, Salem, Portland, and the surrounding Oregon communities, we bring local code expertise and meticulous drafting to every custom project.
Floor Plan Design
Start with a blank slate. We design a floor plan built around how your family actually lives — open or defined, single-story or multi-level.
Exterior & Elevation Design
Your home's character starts on the outside. We develop elevations that define the rooflines, window placement, and style.
ADU & Multi-Family Plans
Building with an ADU? We design both structures together to maximize your lot, meet zoning setbacks, and satisfy Oregon's ADU regulations.
Our Process For Your Custom Home
A custom home succeeds or fails in the planning phase. Every decision made on paper saves time and money in the field. Here is how we ensure success:
Site & Lot Analysis
We start by studying your property. Setbacks, topography, and utility locations all shape what is possible — and what makes sense before a single wall is drawn.
Design & 3D Modeling
We draft the initial layout with you. Using 3D modeling tools, we help you visualize how your home will flow and look before a single nail is hammered.
Code Compliance
We refine the plans to meet the Oregon Residential Specialty Code. This includes energy calculations, seismic bracing considerations, and prescriptive design standards.
Permit-Ready Docs
You receive a full set of plans—including site plans, floor plans, elevations, and cross-sections—ready to submit to your city or county building department
Frequently Asked Questions
Everything you need to know about the planning and permitting process in Oregon.
Do I need an architect to build a custom home in Oregon?
For most residential construction, a licensed architect is not required. A professional drafter like Topline provides the technical drawings needed for permits and construction, often at a lower cost, while still ensuring code compliance and beautiful design.
Can you design a home for a sloped lot?
Yes. Sloped lots are common throughout the Willamette Valley and Portland metro. We design daylight basements, split-level entries, and stepped foundations to work with the grade rather than against it.
Can you help with 'legalizing' an unpermitted addition?
Yes. We can perform a site visit to measure the existing work and create "retroactive" permit plans to help you get your records up to date with the city.
