Property Description
London Square was built in the mid-1960s, when builders had a different sensibility. Homes were designed around generous proportions. Rooms had definition-and by that I mean walls. Every space had a purpose. It's a floor plan that has quietly stood the test of time. We've come full circle. Welcome to 3726 12th St S. The foyer isn't an entry. It's an arrival. Nearly eight feet wide, with a real coat closet and a broad hallway, it sets the tone for everything that follows. Calling the living room generous might be an understatement. The original fireplace, thoughtfully updated with a gas insert, anchors the room, while new sliding glass doors open to the private terrace. Matching doors in the dining room connect both rooms to the outdoors without asking either one to surrender its identity. In 1966, hardwood floors weren't considered an upgrade. They were simply how homes like this were built. The attached garage is accessed directly from the main living level, one of those thoughtful details you don't fully appreciate until you've lived with it. Upstairs, the primary suite is absurdly spacious with a renovated bath. The two secondary bedrooms aren't oversized offices masquerading as bedrooms. They have real closets, real windows and room for more than just a bed. The lower level was built to be part of the house, not an afterthought. Anchored by a second wood-burning fireplace, the recreation room can become whatever your lifestyle dictates-a family room, media room, guest room, home office or a combination of all four. Even the oversized laundry room gets the practical details right, with a utility sink and room to work. Good outdoor space doesn't have to be enormous; it just has to work. Fully fenced and accessible from both the living and dining rooms, this one does.
