About This Home

508 Saint Mary Street

RARE GEM IN THE HEART OF ROCKWALL! Own a piece of Rockwall history, but with the peace of mind of also owning a modern construction home. High-end, unique features and upgrades are throughout this one-of-a-kind custom charmer. With stunning hardwood floors, beautifully exposed beams, crystal doorknobs on solid-core wood doors, glass-front kitchen cabinets, custom tile work in all bathrooms, shiplap, period-appropriate claw foot tub, and an exorbitantly designed primary closet, there has been no detail left untouched. Important to note, the original 977sf structure was completely rebuilt in 2014, including a new modern foundation, plumbing, electrical, HVAC, a tankless hot water heater, insulation, siding, sheetrock, sub-floors, and new roof framing, with an additional 2,233sf of living space custom built in 2016. September of 2025 brought a new class 4 impact-resistant shingle roof, new gutters, four 3-speed bluetooth attic fans, fresh exterior paint, and in March of 2026 a cedar board-on-board and wrought iron fence was installed. The unique upstairs bonus room can be envisioned as a huge second living area, family game room, extra large 4th bedroom & bathroom, office, gym, or one enormous space for them all! The oversized 2.5 car garage features epoxy floors, a commercial stainless steel sink, a refrigerator water connection, pass through garage doors, a 220 electrical outlet, built-in workbench, ceiling-mounted electric heater, ceiling-mounted electric winch, overhead storage racks, and a pre-wired surround sound system. Whether you’re walking to downtown shops and dining, weekend farmers markets, or Harry Myers park, enjoying a front row seat to hometown parades, or simply relaxing on the back porch under the shade of an oak tree and enjoying the peaceful view, this meticulously maintained home beckons you to come, relax, and enjoy making new memories in a timeless, but modern construction home.
