This historic home on an iconic Rosemont street is one of the premier properties in the neighborhood. With extensive additions and high-quality remodeling throughout, it is the perfect blend of traditional and modern charm. A wide front porch offers the perfect spot to relax and enjoy the meticulously maintained, mature landscape. Upon entry, a spacious open foyer greets you with two coat closets and custom built-ins, leading into a light-filled living room with walls of historically preserved windows, skylights, and a cozy fireplace. Just off the living room, a charming library invites quiet reading or a thoughtful game of chess, while a separate home office features two built-in desks and bookshelvesideal for working from home.
