Herlong Architects is a full-service architecture and interior design firm based in Charleston, SC, specializing in custom coastal home design. Each of our projects represents a design solution created for a specific site, often in the context of dramatic vistas and the comforting sanctuary of nature, that blends the seams between home and surroundings.

The beauty that defines each home is planned with the valuable input of our clients, and as such, reflects their unique character and style. From the Lowcountry of the Carolina coast to the hillsides and beaches of the Caribbean, our homes play as one with the beauty of the surrounding landscape. The diversity of talent among our architects and designers contributes to a highly collaborative creative process, with the singular goal of creating homes that simply belong.

Just as the specific site for your home should be incorporated during the design process, so too should the interiors of your home. We believe that a collaborative approach between the owner, architect and interior designer is essential to achieving the seamless blend of form, function and style that creates a truly timeless home and makes the process of designing and building it a pleasure. Offering architecture and interior design services under one roof at Herlong Architects allows us to provide you the opportunity to do just that.
