One-of-a-Kind Outdoor Builds for Function, Beauty, and Lasting Value
Some outdoor projects don’t fit neatly into a standard category—and that’s exactly where we shine. At AC Cornerstone Building, we specialize in designing and building custom specialty structures in Austin, TX, that solve unique problems and enhance your property’s beauty and functionality. Whether you need a breezeway between buildings, a poolside cabana, or a firewood shelter that matches your home’s style, we bring your vision to life with care and craftsmanship.
Specialty structures are custom-built outdoor features that serve a specific purpose or aesthetic goal. Unlike pergolas, decks, or patios that follow more standard templates, specialty structures are fully tailored to your space, needs, and imagination.
Here are just a few examples of what we build:
✅Breezeways connecting garages, homes, or guest quarters
✅Privacy walls or slatted partitions for added seclusion
✅Garden arbors that double as focal points
✅Poolside cabanas for shade and storage
✅Wood shelters and storage enclosures
✅Outdoor shower enclosures
✅Architectural accent walls
✅Custom pavilions or lean-tos attached to existing structures
These projects often blend form and function—solving problems like sun exposure, storage needs, or visual gaps, while elevating the overall look and feel of your outdoor space.

Your home is unique, and your outdoor additions should be, too. We don’t use cookie-cutter templates or mass-produced kits. Instead, we work closely with you to understand how you use your space—and what you want to change about it.
We regularly help homeowners across Austin and Central Texas design and build:
Perfect for connecting a detached garage, guest suite, or workshop to the main home while providing weather protection and architectural flow.
Whether you're blocking a neighbor’s view or shielding a hot tub, we can build attractive slatted or solid screens that blend with your home’s aesthetic.
Add a romantic or modern touch to entryways, pathways, or landscaping zones with custom-designed arbors or trellises.
Create a shaded spot for lounging, towel storage, or entertaining by the pool—customized to your space and style.
Keep things organized with structures that are functional but far from boring—designed to match your home, not clash with it.
Incorporate vertical interest, backdrops for planters, or modern focal points that define your outdoor space.
