About this home
Offered for the first time in more than 80 years, this classic circa-1857 Mansard-style three-family, with more than 3,800 sf of living space, presents a value-add opportunity for owner-occupants, investors, developers, and alike. Ready for its next chapter, the property offers the opportunity to restore to its original architectural charm or explore a range of possibilities, including condominium conversion and building expansion. The generous 12,600-square-foot lot with six off-street parking spaces further enhances the property's significant upside development appeal and long-term investment potential. Ideally located just a few blocks from vibrant Watertown Square, offering easy access to restaurants, cafés, the public library, banks, pharmacies, and everyday amenities. Roughly one mile from Exit 127 off the Massachusetts Turnpike at Newton Corner, the location provides excellent commuter access to Cambridge, Downtown Boston and Logan International Airport.
