Custom-Built Garages for More Space, Better Storage, and Long-Term Value
Need more space for your vehicles, tools, or hobbies? A detached garage is a smart, flexible solution that adds both function and value to your property. At AC Cornerstone Building, we design and build detached garages in Austin, TX, tailored to your needs, budget, and style. Whether you’re looking for a simple two-car garage or a multi-use structure with a loft or workshop, we make the process straightforward and stress-free—from first sketch to final nail.
A detached garage offers more than just a place to park your car. It opens up storage, adds curb appeal, and creates new opportunities for work, play, or future income. Plus, it keeps noise and fumes away from your home—a benefit many homeowners don’t consider until they make the switch.
Here’s why Austin-area homeowners are adding detached garages:
✅ Flexible Layouts: More freedom to build where and how you want—especially helpful on sloped or irregular lots.
✅ Additional Uses: Turn part of your garage into a workshop, gym, guest suite, or home office.
✅ Improved Home Value: Quality-built garages are a long-term asset that appeal to future buyers.
✅ Better Privacy: Keep mess, tools, or projects out of sight and out of your main living space.
✅ Custom Style: Detached garages can complement or contrast your home’s architecture in beautiful ways.
Whether you’re expanding storage or creating a multifunctional outbuilding, we’ll help you plan a garage that makes the most of your property and investment.
Every home—and homeowner—has different needs. That’s why we build garages from the ground up based on your space, usage goals, and style preferences.

Add upper-level storage or finish the loft as a home office, studio, or future guest room.
