Custom Home Builder · Marco Island & Naples

Custom homes, built by the people you actually talk to.

As licensed contractors, we manage your build ourselves — from lot evaluation and permits to the final walkthrough. No middlemen, no project managers you've never met.

What we build

Homes designed for island living.

Custom new homes

Your plan, your finishes, your lot — built to the coastal standards Marco Island and Naples demand.

Spec homes

Move-in-ready luxury homes we build to sell — or build with you as an investment partner.

Select renovations

New construction is our focus, but we take on select renovations and additions — the right projects, done to the same standard.

How a build works

Five steps, one team the whole way.

1

Consultation

We talk through how you want to live, your budget and your timeline.

2

Lot & design

We evaluate the lot — or help you find one — and finalize plans and a detailed estimate.

3

Permits

We prepare and manage your permit applications with the city or county.

4

Construction

We run the job site ourselves and keep you updated directly — wherever you are.

5

Keys

A final walkthrough together, then the keys — backed by our one-year workmanship warranty, plus all manufacturer warranties.

One home, start to finish

From rendering to reality.

Old Marco Lane, Marco Island — follow one of our custom homes from the first drawing to the finished front door.

Local expertise

Building on the coast is different.

Flood zones, elevation requirements, high-wind codes and island logistics all shape what — and how — you can build. After more than a decade here, we plan for them from day one, so there are fewer surprises in your budget and schedule.
