Timeless character and thoughtful updates converge at 309 Mahan Street in the heart of downtown St. Marys. Originally built in 1950, this one-of-a-kind home showcases rich wood-beamed ceilings, original hardwood floors, and a charming galley-style kitchen that honors its mid-century roots. A beautifully executed rear addition enhances both form and function, offering two private offices/FLEX spaces, a spacious owner's suite with ensuite bath, and a cozy living room designed for everyday comfort. Step outside the owner's suite to a screened porch--an ideal place to unwind--overlooking an inviting courtyard designed for both relaxation and entertaining. The outdoor space features a gardening house, tiki hut with the home's original sink, grilling area, and fire pit, creating a setting that feels both intimate and inspired. With both bathrooms thoughtfully remodeled, a new $14K HVAC installed and this distinctive downtown property is ready to welcome its next chapter.
