When you need more space but don’t want to leave the neighborhood you love, building up is often the smartest move. At AC Cornerstone Building, we specialize in second-story additions in Austin, TX—transforming one-story homes into spacious two-level properties that meet your changing needs without sacrificing location, comfort, or design continuity.
Whether you’re looking to add bedrooms, build a private primary suite, or create a second-floor retreat for work or guests, we deliver expert planning, solid construction, and clean integration from start to finish.
In many Austin neighborhoods, especially where lot sizes are tight or property values are high, adding up instead of out is the most practical way to grow your space. Second-story additions help you make the most of your existing footprint while improving your home’s value and functionality.
Homeowners choose second-story additions to:
✅ Stay in the same location while gaining more square footage
✅ Add bedrooms and bathrooms for a growing family
✅ Create a dedicated home office or guest suite
✅ Design a separate living area for aging parents or adult children
✅ Enhance resale value in high-demand neighborhoods
✅ Maximize space without losing backyard or outdoor living areas
We’ve worked with clients across Central Texas to reimagine their homes with thoughtful, well-built additions that feel like they’ve always been part of the house.
The beauty of a second-story addition is that it can be completely tailored to your family’s needs. Whether you need more private spaces, additional bathrooms, or a flexible bonus room, the possibilities are wide open.
Popular second-story layouts include:
Perfect for kids, guests, or multi-generational households
Increase comfort and convenience for everyone
Add luxury and privacy with a spacious upstairs suite
Quiet, dedicated spaces for remote work or hobbies
Open-plan rooms for family activities or study zones
Create a near-independent living space with its own entrance or kitchenette.
At AC Cornerstone Building, we’re known for a clear, steady process that keeps things moving without surprises. Adding a second story involves detailed planning and coordination, and we manage every piece—from permits to punch list—so your build stays on track and stress-free.
Here’s how it works:
We visit your home to listen to your ideas, assess your existing structure, and offer honest, informed feedback. Not every home is ready for a second story—but we’ll help you understand what’s possible.
We work with your architect—or recommend one—to design the new layout and evaluate your home’s foundation and load-bearing capacity. If your slab or frame needs reinforcing, we’ll factor that into the plan.
We handle all required permits, zoning, and code compliance with the City of Austin or your local municipality. Our team is familiar with local building codes and neighborhood associations, so we plan efficiently.
We carefully remove roofing and existing components while preserving the home’s integrity below. Our crew builds cleanly, safely, and with constant communication to minimize disruption to your daily life.
Once framing, utilities, and drywall are complete, we install finishes that match your existing home—or reflect the new style you’ve chosen. You’ll do a final walkthrough with us before we wrap up.
The success of a second-story addition lies in how well it blends with the original home. We go beyond structural work to ensure that every finish—from siding to trim to flooring—feels cohesive and intentional.
We pay close attention to:
Our team brings design awareness, technical skill, and the highest standards of craftsmanship to every stage of your project.
We’ve completed second-story additions across Austin—doubling square footage for families in Tarrytown, adding upstairs bedrooms in Circle C, and transforming bungalows into spacious two-story homes in Brentwood.
