Sullivan's Island Historic Custom Home

This homegrown collaboration between Sea Island Builders and Herlong and Associates combines materials, colors, and design that perfectly compliment the gorgeous waterfront location of this Isle of Palms abode.

Charleston Renovations

From the plentiful Isle of Palms brick ranch homes built in the 1950’s to the pre-Civil War era historic homes along the Charleston Battery, Charleston is full of homes worthy of extensive renovations. Due to their complex nature and often unforeseen conditions, Charleston renovations and additions often require more planning and due diligence than new construction projects.
