Custom home building · Beaverton, OR
Your Custom Home, Built the Beaverton Way.
Whether you're building on a long-held family lot or a new piece of land, a custom home is your chance to get every detail right. De Marco Builders has been turning that chance into finished homes across Beaverton and the Portland metro area since 1996, with a fixed price and a firm deadline behind every one of them.
a Custom Built for Beaverton
Your Home, Built Around You.
The way your family uses a home is unique to you, and the design should start there. That might mean a kitchen built for hosting the whole family, a quiet office tucked away from the noise, or extra square footage set aside for whatever comes next. The point is simple: the design follows your life, not the other way around.
At De Marco Builders, that's the approach we take with every custom home we build. Our team stays with the project the entire way — through design, through permitting, through the final nail — so nothing gets lost in a handoff and nothing gets built on autopilot. Every choice, from the floor plan down to the fixtures, is made with your everyday life in mind, so the finished home actually works the way you need it to.
Design meets construction
One Team.
No Gaps, No Guesswork.
Building a custom home takes more than a good design — it takes a team that manages every phase of construction with the same level of attention, from the first foundation pour to the final walkthrough. At De Marco Builders, that means close, hands-on oversight throughout the build, not a project that's handed off once the permits are approved.
We've applied that same standard of management to more than 1,400 projects across the Portland metro, and it's what allows us to commit to a price and a schedule with confidence — and actually hold to both. For a custom home in Beaverton, that's the difference between a build that goes smoothly and one that turns into a headache.
THE PROCESS
What to Expect.
The process starts with listening — figuring out how you want the home to function before anyone touches a floor plan. From there, we take the project through design, engineering, and permitting, checking in with you at each milestone rather than disappearing until the "big reveal."
Once permits clear, construction starts on the date we committed to, and it stays there. You'll have a single point of contact for the entire build, consistent progress updates, and a finish date that doesn't move — something we've delivered on for more than three decades with a 100% on-time record..

How do you price a project?
Every proposal from De Marco Builders provides complete cost transparency. Our estimates clearly show the construction costs, company overhead, profit, and total project cost so clients fully understand where every dollar is allocated.
Do you require a deposit?
No. Never. We do not require an upfront deposit. The first payment is due only after a portion of the contracted work has been completed.
What happens if costs change during the project?
We guarantee the contract price through project completion unless the homeowner requests additional work beyond the original scope or unforeseen structural conditions are discovered that were not visible during the initial evaluation.
Can you work within a specific budget?
Absolutely. De Marco Builders is a budget-driven builder. We work within the client’s established budget throughout the design, engineering, permitting, and construction phases. We utilize value-engineering principles to maximize quality while maintaining budget goals.
Are you licensed, bonded, and insured?
Yes. De Marco Builders is fully licensed, bonded, and insured. We maintain all required certifications and operate in full compliance with state regulations.
How do you handle unexpected issues that come up mid-project?
Unexpected issues are rare because of our extensive experience and thorough planning process. If an unforeseen issue does arise, it is addressed immediately, typically within 24 hours. We resolve issues in a code-compliant manner while protecting the project schedule.
How often will I receive updates?
Communication is one of our highest priorities. Once a client signs a contract, we maintain frequent communication throughout design, engineering, permitting, and construction. Clients receive regular progress updates, photos, and end-of-day reports so they remain informed from start to finish.
