What additions projects look like in Smyrna
The Smyrna homes we work in are mostly 1990s–2020s suburban developments, plus older town center, typically ranches, newer colonials, and modular and stick-built mix. We've completed projects across Garrison Lake, Smyrna Springs, and the historic town center.
Smyrna projects tend to be value-focused, homeowners getting more space and quality without the Wilmington-suburb premium. We deliver the same craftsmanship at honest local pricing.
