Welcome to Flatfish Island Designs – Coastal Carolina’s premiere provider of purposefully designed, finely detailed, and competitively priced home plans for purchase.

High Quality Home Plans, Competitively Priced

For over 20 years, Stephen Herlong has been creating upscale home designs for homeowners, developers and builders in the Charleston SC area. Now, the same high quality materials, features and finishes you have come to expect from Herlong custom designs are available in a convenient, affordable home plan for purchase.

Home Plans to Inspire your Imagination

Flatfish Island Designs are versatile, practical and varied, but with a coastal cottage charm. They are at home anywhere that sand, surf and sun converge. Our designs are flexible enough to encourage your own imagination, never rigid or creatively stifling. You may purchase one of our home plans to build as-is, take to your own architect, or consult with one of our skilled designers to further customize the interior to your own specifications.

Home Plans based on Decades of Design Experience

Unlike store-bought home plans, Flatfish Island Designs are based on decades of real-world experience, incorporating design expertise gained from:
• Working with hundreds of developers, builders and homeowners;
• Learning about the ways people live, work, play and entertain in their homes; and
• Addressing the unique challenges and requirements of home building on the South Carolina coast.

Purposeful Home Plans for Superior Livability

Decades of Herlong experience allow Flatfish Island Designs to differentiate between design elements that are classic and timeless - and those that are merely passing fancies. This practical, purposeful approach offers years of superior livability for the people who live in our designs, and can improve property values and resale.
