How much does a home addition cost in Austin?

The cost of a home addition in Austin depends on the size of the addition, structural requirements, permitting, utility connections, materials, and interior finishes. Every project is different, so costs vary based on your home's existing layout and your goals. Simply Home develops customized plans and budgets designed around your space and lifestyle.

What should you consider before building a home addition?

Build Up, Out, and Smart

A successful home addition is about more than creating extra square footage. It should complement your home's existing architecture, improve how you live, and add lasting value. Before construction begins, it's important to consider design integration, zoning requirements, permitting, budget, and how the new space will connect with the rest of your home.

What is included in a home addition project?

Every home addition requires careful planning, coordination, and attention to detail. Simply Home assesses the feasibility of each design by evaluating how it will work with the existing conditions of the home, including mechanical, electrical, plumbing, and structural requirements. We also consider how the addition will integrate with the existing home so the new space feels intentional and like it has always been part of the original design. Our job is to make sure what’s being proposed is possible and will work with the home before construction begins, then manage the project from permitting and budgeting through construction.

"Working with Simply Home for this remodel was a breath of fresh air. Their excellent organizational skills, adherence to the timeline, quality of work and clear communication throughout the entire process were truly commendable. We've worked with many contractors and can honestly say that Simply Home was far more organized than others. They diligently managed orders and timelines and had a constant, clear line of communication to ensure everyone was on the same page and there were no surprises. They also delivered quality work and were always willing to problem solve and find the best possible option, all while maintaining positive, "can do" attitudes. We look forward to working with the Simply Home team again!"

“During a very stressful time, hiring Simply Home to help prep my condo to go on the market was one of the best decisions I made. The concierge company handled everything — coordinating with painters, window cleaners and even a handyman to tackle multiple projects. In the end, my place never looked better and — most importantly — it sold in less than 3 days!”

Rachel G.
Homeowner

"We used Simply Home to add a fireplace for our living room and we couldn't be more thrilled with the results. They took care of every detail and provided us with incredible guidance to make sure that our designs delivered what we wanted. We even finished ahead of schedule! Even though it was a relatively small project, you wouldn't have known it from their extreme attention to detail and care over every step. We cannot wait to work with them again!"

Lauren C.
Homeowner

"Simply Home oversaw our kitchen renovation, and we were so grateful to have them on our team. Our Project Manager was communicative throughout the whole project and was always willing to collaborate to find solutions when an issue came up (which is normal in any renovation!). We felt like Simply Home had our back the entire time, and we would absolutely work with them again!"

Robin T.
Homeowner

"Working with Simply Home was a great experience! Their character, processes and communication exceeded my expectations. I felt comfortable with them from the very start. They truly care about the client’s vision and no detail was too small for them to give attention to. They cleaned up the work area after the end of each day, and replaced my air filters which I appreciate because we were living in the house at the time of the renovation. Overall, Simply Home restored my faith in general contractors. I’m very thankful for them and I plan on doing more projects with them in the future."
