Exterior Architecture & Materials

The home’s architectural essence blends Coastal Farmhouse charm with Low Country tradition, resulting in a design that feels both fresh and timeless. The exterior features:

• Metal roofing for longevity, classic appeal, and excellent weather resistance.
• Horizontal lap siding paired with board-and-batten accents to create texture and balance.

• Symmetrical front elevation with clean lines and carefully centered windows for a calm, orderly aesthetic.

These materials are not only beautiful but practical, offering coastal durability, low maintenance, and universal appeal. The architectural language is reminiscent of classic Southern coastal living, yet it adapts perfectly to inland or vacation settings.
