Overview

This one-of-a-kind commercial property offers exceptional architectural character and flexible use. Originally designed as the headquarters for a technology company that developed early Electronic Medical Record (EMR) software for nursing homes, the building was intentionally created to feel more like a home than a traditional office. Inspired by a Southern mansion design and built to commercial specifications, the property features expansive windows, grand dual staircases, a gold chandelier, and warm indirect lighting throughout. The layout includes a full kitchen with high-end appliances, three full bathrooms, an elevator servicing all three levels, a theater room, exercise room, balconies, and two porches. Sixteen stately columns define the exterior, and a large standby generator provides added reliability. Situated on approximately 2.8 acres and currently zoned Highway Business. The parcel may offer potential for division, subject to approvals, due to surrounding residential uses.
