WHAT WE BUILD

Custom homes built the way you actually want to live.

We don't build cookie-cutter homes. Every project starts with how you want to use the space — and everything else follows from there.

01/

Custom homes

Fully custom design-build projects where you're involved at every stage. Built to your vision, not a template.

02/

Design-build packages

Pre-designed plans adapted to your lot and preferences — a faster path to a high-quality custom home without a blank page.

03/

Spec builds

Investment properties built to a high standard — with the finish quality and materials that hold value in the Oregon market.

04/

ADUs & additions

Accessory dwelling units and structural additions that expand what your property can do. Permitted and engineered.

05/

Site & land assessment

We evaluate soil, grade, access, utilities, and zoning. We tell you what's possible before you commit to anything.

06/

Full permit management

We handle every submission, revision, and inspection — so the process moves as fast as it can without cutting corners.

Our builds

Custom homes built across Oregon.

Every home below was built by our own crew — from foundation to finish. Real projects, real clients, real Oregon.

WHY MARSANZ BUILT

What makes a builder worth trusting with your biggest investment.

New construction goes wrong when builders overpromise, underdeliver, and disappear when problems surface. Here's what we do differently.

Transparent pricing from day one

Detailed itemized estimates before any work starts. No low-ball quotes to win the job that escalate later. You know the cost before you commit.

One team, foundation to finish

Our own crew handles the full build. Quality is consistent, scheduling is controlled, and there's one person accountable for all of it.

Oregon-specific expertise

Oregon soil types, seismic code, energy requirements, local permitting. Building here isn't like building anywhere else. We've done it for 12+ years.

How it works

From site visit to the day you get the keys.

New construction is a long process. Here's how we structure it so you always know where you are and what's coming next.

01/

Site & feasibility

We assess land — soil, grade, zoning, utilities. Honest picture of what's buildable before committing.

02/

Design & planning

Floor plan, elevations, and material selections developed together. We work with your architect or provide design directly.

03/

Permits & approvals

We manage the full permitting process — submittals, revisions, responses. We tell you upfront how long and why.

04/

Foundation & framing

Ground breaks. You get milestone updates as each structural phase completes.

05/

Systems & envelope

Roofing, windows, siding, insulation, mechanicals. Building sealed before finishes.

06/

Finishes & handover

Finishes completed, inspections passed, walkthrough together — then the keys are yours.

FINANCING

Don't let the budget hold up the build.

We work with flexible financing options to make your project happen now — not when it's too late. Ask us about payment plans during your estimate call.

01/

Low monthly payments

Spread the cost with manageable installments.

02/

Quick approval

No lengthy process. Get an answer fast.

03/

All services qualify

Roofing, siding, decking, remodeling — all included.

04/

"The team helped me understand each step of the process and answered every question I had. They asked what I wanted, gave me design suggestions, and showed me color options before the project began. They made sure I was completely satisfied with the finished work. The crew completed everything in just two days, exactly as promised. The new flooring and painted walls made a huge difference. They made the whole process go so smoothly."

I can't say enough good things about Edson Martinez and his team at Marsanz Construction. From the first walkthrough to the final walkthrough, they were professional every step of the way and did a truly superior job remodeling our kitchen.

I recently hired Marsanz Construction for a bathroom remodel, new flooring in the basement, and the installation of a new sliding glass door and man door. The team was knowledgeable from our very first conversation and paid close attention to every detail along the way, from material selection to the final walkthrough. Everything was handled professionally from start to finish, and I couldn't be happier with the results. I'd gladly hire them again for future projects.
