  • →Permitting, inspections & trade coordination handled for you
  • →One accountable team from concept through completion
  • →Commercial and residential, across Palm Beach, Martin and St. Lucie counties

Markets We Serve

Two Disciplines.
One Standard.

From tenant improvements and ground-up commercial buildings to custom homes and whole-home renovations, every Keystone project is planned, permitted, and delivered by one team.

What We Do

Our Capabilities

01

Pre-Construction Planning

Scope, budget, and timeline defined before a single permit is pulled — the phase most projects skip, and where most problems start.

02

Construction Management

One point of contact coordinating every trade, inspection, and milestone, with total accountability for the outcome.

03

Design Coordination

We work alongside your architect and designer so the plans, the budget and the build stay aligned.

04

Permit & Municipality Coordination

Permitting, plan review, and inspections managed across Palm Beach, Martin and St. Lucie counties so permit issues are caught early.

05

General Contracting

Licensed, insured execution by trusted trade partners we have worked with for years — not strangers off a list.

06

Custom Fabrication

Specialty metal and custom build elements fabricated to fit the project, not adapted from something off the shelf.

How We Work

The Keystone Method.
Every Project, Every Time.

A six-phase method that removes the uncertainty most projects run on. Every client knows exactly where their project stands — from the first conversation through long-term support.

The Keystone Method

We listen, assess the space, and understand what success looks like for your project.
02
Plan
Scope, budget, and timeline are defined and locked before any work begins.
03
Design
We coordinate design and engineering so the plan is buildable and complete.
04
Build
Daily oversight and trade coordination, each phase inspected before the next.
05
Deliver
Final inspection, punch list, and a walkthrough you sign off on yourself.
06
Support
We stand behind the work and stay reachable long after the project closes.
