Plans That Fit Your Lot, Home, and Lifestyle

Custom Deck Design & Construction

Built Around Slope, Shade, Traffic & Code

Smart Design for Every Detail

A custom deck starts with the right questions: How will you use it? What does the yard allow? How much shade, storage, or seating do you need? We walk you through layout, stairs, railing, materials, and city permits—then build it from the ground up to fit.

Because No Two Yards—or Families—Are the Same

Why Custom Deck Design Matters

You don’t need a cookie-cutter deck. You need something that works with your home’s footprint and how you actually live. We design around slope, sun, furniture, stairs, and HOA or permit needs—so it all comes together cleanly, safely, and with real usability.

  • Layouts tailored to your yard and elevation

  • Decks for grilling, relaxing, or entertaining

  • Code-compliant designs and permit support

From Concept to Permit-Ready

We Handle the Design, the Drawings, and the Approvals

You bring the ideas—we’ll handle the structure, specs, and city submittals. Whether it’s a second-story platform, ground-level lounge, or wraparound rebuild, we’ll produce full plans that are buildable and approved fast. You’ll get a deck that’s safe, stylish, and 100% permitted.

Engineered Layouts That Actually Last

A deck isn’t just boards—it’s footings, framing, and fastening that resist shifting soil and Midwest weather. We measure, design, and build for long-term performance from the start. No guesswork. Just clean lines, proper drainage, and structural integrity you can trust.

Materials That Fit Your Budget and Look

Choose What Works With Your Home

Trex, TimberTech, cedar, pressure-treated pine—we know how to match the right product to your goals. Some clients want low maintenance. Others want natural wood. We’ll walk you through every choice so the finish, color, and feel match your home and your lifestyle.

Don’t Settle for a Pre-Fab Deck That Doesn’t Fit

Factory decks often ignore your yard’s slope, shade, or layout. Our custom builds use every inch wisely. We make sure your deck flows with your space, feels natural to use, and fits your daily life—so it doesn’t just look good, it works better.

  • Designs that maximize usable space

  • Railing, stairs, and zones placed with intent

  • Every inch customized to how you live

Built Safe, Level, and to Every Code

Decks That Pass Every Inspection

We design decks to meet or exceed IRC and local building codes. That means correct post depth, guardrail height, joist spacing, and fastening methods. From structural safety to clean finishes, your deck will be ready for city inspection—and everyday use.

What Homeowners Ask About Custom Decks

From layout planning to city inspections, most homeowners have similar concerns when it comes to custom decks. Below are the most common questions we answer before we ever pick up a tool.

Do I need to provide plans before getting a quote?

No. We’ll design your deck layout as part of the quote process, then create full permit-ready drawings once you approve.

Can you help me decide between wood and composite?

Yes. We’ll walk you through cost, maintenance, and appearance for each option—and help you choose what’s best for your lifestyle.

How long does it take to get a permit?

Most permits take 1–2 weeks. We submit all drawings and manage approvals so your build stays on track.

Do you build on sloped or walkout lots?

Absolutely. We design for grade changes, elevated builds, and multi-level structures with safety and drainage in mind.
