An understated expression of Louisville living, this corner-lot residence merges a coveted Sundance setting with an easy sense of light, space and connection. Recently refreshed kitchen, baths, and with new flooring throughout, the home feels bright, relaxed and immediately welcoming. A south-facing orientation fills the interiors with natural light, while the thoughtful floor plan creates a sense of spaciousness. The main level flows easily between living and dining spaces, with a flexible area that adapts beautifully to the rhythms of everyday life. Upstairs, two bedrooms and baths offer privacy, while the finished lower level introduces another dimension of versatility with space for a home office, additional living area or guest retreat, complete with a deep soaking tub. Outside, mature landscaping lends shade and privacy to a backyard designed for lingering, with a generous brick patio providing a natural setting for morning coffee, summer dinners and evenings under the stars. Queen Anne Victorian-inspired architectural details add distinctive character to the home's exterior, while its larger-than-typical corner lot gives it an especially rare presence within the neighborhood. Across the street a neighborhood connector trail provides quick access to Warembourg Open Space, and pop down Pine Street to be in downtown Louisville in minutes.
