TESTIMONIALS

Our Satisfied Clients

Built for St. Augustine's Timeless Character

St. Augustine spans from the ancient coquina walls of the Colonial Quarter to modern master-planned communities. We're intimately familiar with requirements throughout the city - from the strict Historic Architectural Review Board (HARB) guidelines in the downtown historic district to the standards of newer developments near Palencia and Julington Creek. Our ADU projects honor the architectural traditions found along St. George Street and in neighborhoods near the Lightner Museum while incorporating modern amenities and meeting current Florida Building Code requirements. Whether your property is in Davis Shores, Lincolnville, or one of the golf course communities, we create ADUs that respect St. Augustine's unique heritage.
