How St. Pierre Construction Relocated a Historic Sullivan’s Island Cottage
For most homeowners, “home moving day” means packing boxes, labeling tape, and hoping nothing fragile breaks along the way. For the team at St. Pierre Construction, moving can mean something entirely different.
In this case, it meant relocating an entire historic cottage; carefully lifting a structure that has stood for over a century and giving it a new, safer foundation for the next hundred years. On Sullivan’s Island, where history, climate, and coastal living intersect, projects like this are not just construction challenges, they are acts of preservation.
Why Move a Historic Cottage?
Barrier islands like Sullivan’s Island are constantly evolving. Many of the island’s most charming cottages were originally built in the late 1800s and early 1900s, which is a long time before modern flood maps, FEMA requirements, and today’s building codes existed.
These homes were often constructed close to grade, which now presents several challenges:
- Rising base flood elevations
- Increased storm surge risk
- Aging foundations impacted by moisture and time
- Stricter zoning and building compliance requirements
Rather than demolish these architecturally significant homes, many homeowners choose a better path; lifting and relocating the structure while preserving its historic character.
This approach allows the home to meet modern safety standards without losing the craftsmanship and charm that make Sullivan’s Island so unique.
Step 1: Research and Approvals:
Before any physical work begins, extensive planning and approvals are required. Sullivan’s Island maintains a strong commitment to historic preservation, meaning every project must be carefully reviewed by:
- The Town of Sullivan’s Island
- Local historic preservation authorities
- Zoning and floodplain administrators
Because the island is part of the broader Charleston historic landscape, oversight is detailed and intentional.
Documentation often includes:
- Structural engineering assessments
- Architectural surveys
- Historic significance reports
- Elevation and flood compliance plans
The goal is clear: ensure safety and resilience while protecting the home’s historic identity.
Step 2: Structural Preparation
Most historic cottages on Sullivan’s Island were built using materials and methods that predate modern construction standards. Some of the most common predated materials and methods include:
- Heart pine framing
- Wood clapboard siding
- Pier-based foundations
- Masonry chimneys
Before lifting begins, the structure must be stabilized.
The St. Pierre Construction team carefully:
- Reinforces the framing from below
- Installs steel beams to evenly distribute weight
- Disconnects all utilities
- Removes or protects fragile architectural elements such as porches or chimneys
Every step is deliberate. These homes were not designed to be moved, so precision is critical to prevent structural stress or damage.
Step 3 Home Moving Day: The Lift
Lifting an entire home is a slow, methodical process, and not a dramatic one. Hydraulic jacks are positioned beneath the beam system and work in synchronized increments, often raising the structure just inches at a time.
This phase requires:
- Dozens of jacks operating in unison
- Continuous monitoring for structural stress
- Real-time adjustments to maintain balance
On a sandy barrier island like Sullivan’s, soil conditions add another layer of complexity. Engineers hookup closely with contractors to ensure the ground can support both the lift and the future foundation.
Step 4: Moving the Cottage:
If relocation is required, the home is transferred onto a specialized moving system using dollies or unified hydraulic platforms. On Sullivan’s Island, this is no small feat.
Challenges include:
- Navigating narrow residential roads
- Coordinating with overhead utility lines
- Securing police escorts when necessary
- Monitoring coastal wind and weather conditions
Unlike urban moves in downtown Charleston, island relocations must also account for bridge access, soft ground conditions, and exposure to coastal elements. Every movement is carefully choreographed to protect both the structure and the surrounding environment.
Step 5: Building a New Foundation
Once the entire home was moved, the structure is placed on a new foundation designed to meet modern flood and structural standards.
Typical foundation systems include:
- Deep helical piles for stability
- Reinforced grade beams
- Elevated masonry foundations aligned with FEMA base flood elevation requirements
One of the most important design considerations is maintaining the home’s original proportions. Too much visible foundation can dramatically alter the character of a historic cottage. To preserve its aesthetic, St. Pierre Construction incorporates:
- Traditional lattice screening
- Tabby or brick veneer finishes
- Historically appropriate staircases and entry points
The result is a Lowcountry Coastal home that feels authentic; as well as being safer and stronger.
Step 6: Restoration and Preservation:
With the home set in place, restoration begins. This phase focuses on honoring the original craftsmanship while subtly integrating modern systems:
- Original siding is repaired or replaced in kind
- Historic windows are restored whenever possible
- Mechanical, electrical, and plumbing systems are updated discreetly
- Rooflines, dormers, and architectural details are preserved
This is not a renovation focused on modernization; it is a commitment to stewardship. Many Sullivan’s Island cottages reflect a blend of coastal vernacular architecture, Charleston influence, and historical ties to nearby Fort Moultrie. Each detail matters.
Unique Challenges of Barrier Island Construction:
Home moving and relocation projects like this require specialized expertise due to the island environment.
Key challenges include:
- Salt air corrosion impacting materials
- Termite exposure in older wood structures
- Tight lot lines and limited access
- Protected live oak trees that cannot be disturbed
- Scheduling around hurricane season
Success depends on seamless coordination between engineers, preservation experts, and experienced builders who understand coastal construction.
The Emotional Side of Moving a Home:
These Coastal Lowcountry cottages are more than structures; they are part of family histories. Many have been passed down through generations, holding decades of memories within their walls. The idea of lifting and moving one can feel overwhelming. But when the process is complete, and the home rests securely on a new foundation, the result is deeply rewarding.
Preservation allows:
Future generations to experience authentic coastal living
Architectural heritage to endure
Neighborhood character to remain intact
A New Chapter for an Old Home:
When done correctly, moving a historic cottage does not erase its past; it protects it. On Sullivan’s Island, where resilience is just as important as tradition, projects like this represent the best of both worlds.
St. Pierre Construction approaches each home with the understanding that they are not just building structures; they are preserving stories. And sometimes, the best way to protect history… is to move it.
