Custom Barn Builders

Wildwood Barn Builders is obsessed with one thing, building accessory buildings.

At Wildwood, we specialize exclusively in custom accessory structures—barns, garages, and custom lifestyle buildings designed to enhance your home and create more room for what matters most. We’ve refined our systems to make the process smooth and stress-free, handling everything from permitting and excavation to the final finishing touches so you can stay focused on your family, not the details.
By staying current with proven building techniques, quality materials, and thoughtful design, we deliver durable, beautiful structures built to last. We’re passionate about creating spaces that free up your home (and your weekends) so you can make more memories with family.
Across our site, you’ll find helpful videos, walkthroughs, and downloadable guides to clarify your options, timeline, and expectations—so you can walk away informed, whether you build with us or not.

Reclaim Your Space in Greenville

In Greenville, we build structures designed for how you actually live:
Do you have a garage, but you’re still parking outside?
Be the ideal host. Give your guests their own place to stay.
Tired of wrenching in your driveway? Build the workshop that’ll make life easier.
Feeling creative? Paint studio, wood shop, or a place for your 3d printers.
Build the home gym that keeps you close to the family and gets them involved. How about a golf simulator with buddies at your place?
Need a real office at home? The kitchen table isn't making you more efficient.
Sports family? Basketball, baseball, or gymnastics at home. Year round.
Kids bouncing off the wall? What if they could do that somewhere that wouldn't make a mess for everyone to see.
Additions are expensive and invasive. Remodels don’t create more space, they just change it.
A barn, garage or accessory building adds square footage for less. More possibilities, less pain.

Your Dream space, customized for you.
