New Braunfels Custom Home Builder

Cost-plus custom homes and large remodels in New Braunfels and the Texas Hill Country

Building a home is unfamiliar territory for almost everyone.

Most people know what they want their home to feel like. Almost nobody knows what it costs or what to do first.

Mustard Custom Homes takes your plans, prices them from real subcontractor bids, and builds the home with the books open from the first draw to the last.
 YOUR DREAM HOME, BUILT WITHOUT THE HASSLE

We manage every detail, from first designs to final touches.

Building your home should be a joy, not a burden. You can trust that your vision is in expert hands — leaving you to focus on creating a home that reflects you.
  • Transparent budget — clear, upfront costs with no surprises.
  • Expert project management — every trade and timeline handled.
  • Clear communication — you're always in the loop.

What does cost-plus mean for you?

Cost-plus means you pay the actual cost of building your home, plus a fee we agree to before we start. Here is what that changes.

You see every bid.

Every line item goes out to our vetted subcontractors, and you see all of them - not just the bottom line. You'll know what they charge before anyone starts.

Savings stay with you.

When a trade comes in under estimate, that money stays in your budget instead of ours. On a fixed price, the builder keeps the difference and you never learn it existed.

The books stay open.

Bids and invoices are available to you at any point in the project. We deliver updated numbers with every draw, so you always know where your money has gone and what is left.

The percentage never moves.

Our fee is set in your contract at signing and stays there. The dollar amount rises and falls with your selections and change orders - which means it moves with your project, not against it.

Andrew caught the vision we had for our home, and was patient to brainstorm with us realistic options within our limitations to bring our hopes to fruition. His experience, resourcefulness and follow through with each phase helped us realize what we couldn’t have dreamed on our own. I still cant believe we get to call it home!
