Ground-Up Custom Luxury in the Lowcountry
Building a custom home in Charleston isn't just about pouring concrete and framing walls—it’s about crafting a legacy property that stands up to the coastal elements while capturing the timeless charm of lowcountry architecture.
At Redstone Building Group, we specialize in high-end, ground-up custom residential construction. From sprawling waterfront estates on Kiawah and Johns Island to elevated, historic-inspired designs in Mt. Pleasant and downtown Charleston, we handle every phase of your build with uncompromising precision.
Our Structural Design & Build Strategy
To ensure your custom home is both architecturally stunning and structurally resilient, we utilize a specialized, integrated approach:
- Elevated Engineered Foundations: Designing custom pier, stem-wall, or drive-pile foundations engineered specifically for lowcountry flood zones ($V$ and $A$ zones) and coastal soil conditions.
- High-Wind Structural Framing: Utilizing continuous load-path engineering, hurricane straps, and advanced impact-rated building envelopes to withstand coastal winds up to 140-150 mph.
- Custom Lowcountry Vernacular: Seamlessly integrating iconic architectural features, including expansive wrapped piazzas, exposed rafter tails, gas lantern entryways, and premium metal standing-seam roofing.
- Building Envelope Science: Deploying advanced moisture-management systems, flashing, and open-cell spray foam insulation to combat high Southern humidity and maximize thermal efficiency.
The Ground-Up Process
Phase 1: Pre-Construction & Design
- Site Evaluation: Analyzing your lot’s topography, tree preservation requirements, and solar orientation.
- Architectural Review: Collaborating with your architect (or introducing you to one of our trusted local partners) to ensure the design matches your lifestyle and budget.
- Permitting & Zoning: Navigating the complex Charleston area regulatory approvals, including OCRM (Ocean and Coastal Resource Management) and local ARB (Architectural Review Board) requirements.
Phase 2: Site Preparation & Foundation
- Clearing & Grading: Preparing the building pad while carefully protecting grand oaks and native lowcountry landscaping.
- Coastal Engineering: Executing precise soil compaction testing and structural engineering assessments.
- Foundation Construction: Installing your home's structural backbone, whether it requires elevated timber pilings, a structural stem wall, or a traditional slab tailored to your specific flood zone.
Phase 3: Structural Framing & Envelope
- High-Wind Framing: Constructing the heavy timber or advanced structural framing, integrating continuous tie-down load paths from foundation to roof.
- Weatherproofing: Wrapping the structure in premium moisture barriers and flashing engineered to withstand intense coastal driving rain.
- Mechanical Rough-ins: Installing high-efficiency HVAC systems with dehumidification, custom plumbing, and smart-home electrical infrastructure before the walls are closed.
Phase 4: Interior Finishes & Handover
- Fixtures & Handover: Installing your high-end appliances, tile surfaces, and lighting fixtures,
- Insulation & Drywall: Deploying open-cell spray foam insulation to seal the home from Southern humidity, followed by flawless drywall hanging and finishing.
- Custom Millwork: Installing our bench-crafted cabinetry, custom trim, ship-lap, or historic-inspired molding.
