Owner's Representation

Start with the Cornerstone.

Cornerstone provides independent Owner's Representation through every stage of the project. As your Owner's Representative, we work for you.

Why an Owner's Representative

Building has changed. You don't have to go it alone.


Building has become a difficult process. It isn't what it used to be. Projects are more complex than ever, and owners are often left on the outside, unsure what's happening or whether the work is being done right.

Whether you're planning a renovation or a new build, Cornerstone guides you through every phase. We help you plan the project, select the right team, review bids and keep the work on track from start to finish.

After you purchase a home, what comes next?

Many homeowners begin considering improvements shortly after they purchase. If you're thinking about making changes to your new home but don't know where to start, call Cornerstone. We'll help you get started.

Thinking about renovating, but not sure where to begin?

If you've been putting off changes to your home because you don't know where to start, call Cornerstone Construction Advisors. We'll help you get started.

Already working with a designer or contractor?

We work alongside your team at any stage.

Our system

A construction management system designed exclusively for owners.


Start with a clear plan

Quality control you can see

Scheduled site visits focused on workmanship, with GPS, time- and date-stamped photo documentation of the work.

Your project in your pocket

Photos, field reports and progress updates in your own project app, on your phone, tablet or computer. You see what we see.

How our fees work

Phase by phase. One commitment at a time.


  1. PreliminaryPlan, scope, budget and team
  2. Demo & Site WorkObservation as work begins
  3. Structural to Dry-InFraming through a weathertight shell
  4. Rough-InSystems inside the walls
  5. FinishesThe details you live with
  6. CloseoutPunch list and final records

Our fees are set phase by phase, sized to how involved we are in each one. Early phases need lighter observation. From rough-in forward, we're on site more often, because that's where the details matter most.

You commit one phase at a time. Each phase ends with a clear decision point, so you always know where the project stands before the next one begins.

Why Cornerstone

Decades on the builder's side. Now working for the owner.


My name is David Anderson. I'm a fourth-generation Floridian, born and raised in North Florida, and I spent decades as a construction executive, the last fifteen years building ultra-luxury homes in Palm Beach.

As a contractor, I saw how hard it was to keep owners informed. Owners grow uneasy when they don't know what's happening on their own project. That led me to develop a construction management system designed exclusively for owners, built around your own app, with complete visibility from anywhere.

Now I've come home to open our North Florida office, serving Duval, St. Johns and Nassau counties alongside our North Palm Beach office. We work on the owner's side of the table.
