Where Your Outdoor Vision Meets Expert Construction

Custom Deck Design & Construction in Oregon

Design‑In‑Built. Framed to Code. Built for Life.

Complete Deck Builds Tailored to Your Home & Yard

We start each project by listening: material preference, layout goals, how you use your outdoor space. Then we frame it with Oregon‑rated lumber or steel, select fasteners built for the coastal/mountain climate, and finish with clean, lasting surfaces. We coordinate permitting with Oregon’s building codes and local municipality rules, so your deck is safe, solid—and ready for enjoy‑along.

Everything Included. No Guesswork.

From Vision to Verified Permit to Backyard Reality

Decks Designed for Oregon Terrain, Codes & Conditions

Whether your home sits on a slope in Eugene or a flat lot in Salem, our team designs to match both land and law. We understand Oregon’s snow load zones, seismic considerations, and local railing height laws. We build to pass inspection the first time—no rework, no delays. And with material choices suited to wet winters and sun-soaked summers, your deck stays safe and beautiful year after year.

Natural Materials or Composite—We Build Both Right

Your Choice of Decking, Our Guarantee on Structure

We work with cedar, pressure-treated pine, and top composite brands like Trex and TimberTech. Whether you want the warmth of real wood or the low-maintenance ease of capped boards, we frame and fasten everything to perform in Oregon’s seasons. Balusters don’t wobble, treads don’t creak, and boards won’t cup or split. Our builds last—and they look good doing it.

Backyard Decks That Feel Like Part of Your Home

We Match Your Home’s Style, Layout & Elevation

We don’t drop a square onto your lot—we design around it. Our decks blend with your home’s lines, your door heights, and your landscape. From stairs that land naturally to platforms that maximize sun or shade, our decks feel intentional—not afterthoughts. We also coordinate colors, rail styles, and trim for a seamless look. [

A Better Deck Starts With a Better Builder

We don’t just install decks—we build structures that stand up to weather, use, and inspection. Our framing is overbuilt, our fasteners rated, and our finish clean.

  • Engineered plans and permitting included for most Oregon cities

  • Sloped drainage, stair safety, and hardware all meet code

  • Composite or wood options sealed and spaced for performance

One Contractor. One Contract. Zero Runaround.

We Handle It All—Design, Build, and Approval

We don’t hand you off to subs or make you coordinate contractors. Our in-house team designs, frames, builds, and finishes your deck—without gaps or handoffs. From first sketch to final rail cap, you deal with one builder. That means faster answers, tighter schedules, and better results.

From Slope to Spec to Stain—We’ve Got It Covered

FAQs About Custom Deck Construction in Oregon

These are the most common questions homeowners in Oregon ask us before building a custom deck.

Do I need a permit for a deck in Oregon?

Yes. We handle the entire permitting process, including engineering and local submission.

What materials hold up best in Oregon?

Composite and cedar are both great choices—cedar needs more maintenance; composite resists moisture and fading.

How long does a deck build take?

Most projects take 1–3 weeks depending on size, site, and permitting timelines.

Can I build a deck on a slope?

Absolutely. We use deep footings, pier systems, and multi-tier framing to handle uneven terrain.
