Smart Ways to Expand Your Living Space

Your house needs to work for your actual day-to-day life. If you need more room because the family is growing, building on is usually a hell of a lot better than dealing with the stress of moving. At Basey Construction Services, we focus on making these new spaces blend right into your current daily routine.

Our crew regularly takes on tough second-story expansions, detached guest suites, and main-floor family room extensions. We make sure the foundation is solid, and the framing matches up perfectly, delivering premium home additions in Austin, TX that look like they belonged there all along. From quiet home offices to bigger living areas, we build functional spaces that make your home more comfortable while driving up its actual market value.

Discovery & Initial Consultation

We sit down to discuss your goals, budget, and ideas. We look at your existing lot and structure to figure out exactly what’s possible for your home additions in Austin, TX.

Architectural Design & Permits

We draft the blueprints so the new layout connects logically with your current floor plan. Our team handles the city paperwork and works with local building departments to secure every necessary permit before any tools arrive on site.

Framing & Structural Construction

This is where the actual build begins. Our crew handles the foundation, framing, and roofing, focusing heavily on the structural tie-ins to ensure the connection between the old house and the new build is completely solid.

Interior Finishes & Handover

We bring in the trades for drywall, flooring, electrical, plumbing, and custom trim. Once we pass final inspections and clean the job site top to bottom, we hand over the keys to a space that is ready to use.

Frequently Asked Questions

Have questions about expanding your home? Here are a few things we hear most often from local homeowners.

Do I need to move out during the construction of Austin home additions?

It depends entirely on the job. If we are building a detached suite or a simple ground-floor room, you can usually stay put. But if we are pulling off large sections of your roof for a major second-story expansion, we recommend finding a temporary place to stay for safety.

We spend a lot of time matching materials up front. Our crew sources siding, shingles, and paint that complement your current exterior. Inside, we match your existing ceiling heights, trim styles, and flooring transitions so the final result looks like it was part of the original house layout.
Homeowners choose Basey Construction Services because we bring over thirty years of hands-on experience to every single job site. We do not use cookie-cutter plans. Our team builds top-tier structural additions tailored to your specific budget, handling everything from the initial city permits to the final custom carpentry trim work.
Yes. Adding real square footage is a reliable way to boost your market value. Desirable spaces like extra bedrooms, main suites, or larger kitchens offer great returns. Plus, building on saves you from the steep real estate fees, closing costs, and massive headaches that come with buying a new house.
We deal with the city directly, so you do not have to. Austin has notoriously tight rules on setbacks, tree preservation, and impervious cover limits. Our team knows these local codes inside and out, and we handle all the back-and-forth paperwork to get your project fully approved.
