Approved plans re-imagine this property as a sophisticated three-level single-family home that seamlessly blends historic character with modern livability. The 3,080-square-foot design transforms the existing carriage house into an open, light-filled residence featuring connected living and dining spaces, a modern kitchen with direct access to a private garden and bluestone terrace, and a functional mudroom entry. Upstairs, four well-proportioned bedrooms and 2.5 baths offer flexibility and comfort, while the finished lower level provides valuable space for a fifth bedroom, office, or gym and bathroom. The approved site plan includes two off-street parking spaces, privacy fencing, and professionally designed plantings with a curated mix of native and ornamental species. Preservation and planning approvals are in place, allowing a developer, builder, or end user to move directly into construction on a distinctive, design-forward home in one of Brookline’s most desirable neighborhoods.
