Your architect designs. Your builder builds. We represent you.

Building or renovating a home is one of the largest financial decisions most people make. Your builder brings the expertise to build it. Luxona provides independent, experienced representation focused on your priorities, decisions and investment throughout the project.

Luxona advisory documents laid out on a desk: a proposal comparison summary weighing two bids side by side, a scope review, and an advisory review with recommendations
Two proposals compared line by line, scope gaps identified, and a written recommendation before anything is signed.

The Luxona Method: Verify. Compare. Represent.

Verify

Confirm the credentials, scope, and terms behind every proposal before you commit.

Compare

Our fees are flat and never a percentage of your project. Your licensed contractor remains responsible for the work, and you make every decision.

Your builder builds the home.
