How we work together

A clear path from first conversation to the day your family is gathered on the new deck. No surprises. No vague timelines. No hidden costs.

The conversation

We sit down on-site. You tell us how you want to use the space, who you're hosting, what matters most. We listen. No quote pressure, no upsell.

Design & honest pricing

You get detailed drawings and a full investment breakdown before any work starts. Everything in writing. The number you see is the number you pay.

Built with craft

Steve runs the job. Same crew start to finish. We handle permits, HOA approvals, and inspections so you don't have to. On time, on budget.

The next chapter

Your space, ready to host. We stand behind every project with our workmanship guarantee. Twenty years from now, we'll still pick up the phone.

What we build

Custom outdoor living for Central Texas homeowners who want their backyard to be the place everyone wants to be.

Decks

Custom decks designed for the way you'll actually use them. Sunday dinners with the grandkids, morning coffee, big-table holidays. Built with materials that handle Texas heat and last decades.

Patios

Beautiful, durable patios that turn your backyard into an extension of your home. Hill Country limestone, flagstone, stamped concrete. We'll help you pick the right material for your space and your style.

Outdoor Kitchens

Full outdoor kitchens for serious entertaining. Grills, smokers, prep counters, pizza ovens. Built so you're cooking with your guests, not stuck inside while they have the fun.

Pergolas & Covers

Shade structures that make your outdoor space usable in July. Cedar, steel, custom designs that complement your home's architecture and let you enjoy the yard year-round.

Roof Extensions

Covered outdoor rooms that feel like a natural part of the house. Seamless integration with your existing structure. Permitted, engineered, and built to code.

Custom Projects

Fire pits, fencing, retaining walls, custom carpentry. If it's outdoor construction and it needs to be done right, we can build it. Just ask.

Meet Steve

Steve Carnes is a veteran and the owner of KDC Designs. He acquired the business in 2024 from founder Jim Kelton, who's now semi-retired but still involved on jobs, and kept the same crew that's been building these decks for years. New ownership, same builders, same standards.

When you hire KDC, you're not getting a sales rep, a project manager, or a subcontractor. You're getting Steve and a team of people who've been doing this together for a long time. When a design question comes up on-site, it gets answered by someone who's built a thousand of these.

That continuity is the whole point. Two decades of craft, the same hands doing the work, and an owner whose name is on every project. When Steve commits to building you something, he commits to building it right. On time, on budget. Built to last as long as you're in the home.

What our clients say

Real Central Texas homeowners. Real projects. Verified Google reviews.

KDC Designs did an amazing job on the outdoor kitchen. They handled everything: the design, build-out, and installation of all the equipment, including the BBQ, side burner, refrigerator, storage, stone slab counter top, and electrical to name a few. The whole process was smooth from start to finish, and their attention to detail really shows in the final product. The space looks fantastic and functions perfectly. I'd highly recommend KDC Designs to anyone looking to add an outdoor kitchen or upgrade their outdoor living area.

Phenomenal group of people to work with. Ingrid, Steve and their contractors went out of their way to deliver and meet our expectations. KDC takes the time required to thoroughly design and provide feedback. They checked in regularly at each stage of the project and did a quality check. Anyone who needs any kind of outdoor work should engage them with no hesitation.

Common questions

The questions most Central Texas homeowners ask before hiring KDC. If yours isn't here, just call.

What areas of Central Texas does KDC Designs serve?

KDC Designs builds throughout Austin and the surrounding Central Texas area, including Round Rock, Westlake, West Lake Hills, Lakeway, Bee Cave, Dripping Springs, Cedar Park, Georgetown, Pflugerville, and Leander. If you're nearby and don't see your area listed, give us a call.

Is KDC Designs veteran-owned?

Yes. KDC Designs is proudly owned and operated by veteran Steve Carnes, who acquired the business from founder Jim Kelton in 2024. The same experienced crew that has been building decks across Central Texas for over two decades continues to build every project.

What warranty does KDC offer?

Every KDC project is backed by a 2-year workmanship warranty and a 5-year structural warranty. As a TimberTech Gold Dealer, KDC also offers the full extended manufacturer warranty on premium composite decking products, up to 50 years.

Does KDC handle permits and HOA approvals?

Yes. We handle all city permits, HOA approvals, and required inspections as part of every project. Homeowners don't need to navigate the paperwork themselves. That's part of the job.

What materials do you recommend for Central Texas?

Central Texas heat and weather are hard on outdoor materials. As a TimberTech Gold Dealer, we recommend TimberTech composite for low-maintenance longevity. We also offer pressure-treated lumber, cedar, ipe, and other premium options based on your design preferences and budget. Steve will walk you through the pros and cons of each during your consultation.

How long does a custom deck project take?

Timelines vary by scope, materials, and permitting. A typical custom deck takes 4 to 8 weeks from contract to completion. Larger projects with covers, outdoor kitchens, or roof extensions may take 8 to 12 weeks. You get a detailed timeline in writing before any work begins, and we hold to it.

Are you bonded and insured?

Yes. KDC Designs is fully bonded and insured, and is a BBB Accredited business. Texas does not require a state contractor's license for residential outdoor construction.

What does a consultation cost?

Nothing. Initial consultations are free. Steve comes to your home, listens to your vision, and provides detailed drawings and an honest investment breakdown before you commit to anything. No pressure, no upsell.

Let's talk about your space

Schedule a no-pressure consultation with Steve. He'll come out, listen to what you have in mind, and tell you honestly whether KDC is the right fit. No hard sell. No surprise fees. Just a conversation.
