A Custom Home Builder & Renovation Company
Southern Harbor Construction is a licensed general contractor based in Charleston, SC. We build fully custom homes on land our clients own, rework existing homes through whole-home renovations and major additions, and coordinate design, estimating, and construction as one connected process.
Our approach is organized and personalized: clear estimating before you commit, design decisions guided rather than rushed, and a structured project management process that keeps communication, scheduling, and construction moving forward.
A Better Organized Way to Build
Fully Custom
Projects are developed around your property, lifestyle, priorities, and goals — not a fixed catalog of plans.
Clear Estimating
Detailed estimating helps you better understand project scope and expected investment before you commit.
Design + Construction Coordination
Design decisions, selections, planning, and construction are managed as one connected process.
Organized Project Management
A structured process keeps communication, scheduling, decisions, and construction moving forward.
What Our Clients Say
We worked with Justin and his team over a year on a big project- my parents house (over 4200 sqft) had mold damage and had to be ripped to the studs and completely redone. building is always a difficult process but Justin and his team made it as easy as it could be. They worked with us on our specific needs and asks, had great communication, were understanding and very thoughtful, kind, and professional. I've worked with other builders in the past, and I can't speak more highly of Justin and his team.

Justin and his team did a phenomenal job designing our home for us. They were very patient, detailed, and communicated everything effectively with us during the process. SH have built beautiful homes which is why we went with them in the first place. They understood our needs and wants and tailored to our interest. I strongly recommend considering SH when designing a custom home.
