Impeccably crafted 1910 William H. Park Tudor Revival seamlessly transitioned from a grand, single family into an exceptional three-unit dwelling. The main unit is perfectly suited for owner-occupant with more bedroom potential (1st floor office and spacious attic). Both desirable, rear apartments offer steady income and, or ideal in-law / au pair options with a designated patio. The owner's unit was expanded with an additional 1,202 sq. ft of brilliantly refinished below-grade space accessed via a new in-unit staircase (owner's gross living area is 4,994, plus 1212 attic). The striking, climate-controlled expansion includes a rec room, soundproof exercise / music room, bathroom with radiant heat flooring and infrared sauna, laundry room, and storage. Effortless entertaining flow between the stunning living room, cheery dining room, modern kitchen with butler's pantry and period cabinetry leads onto the owner's private porch and enclosed yard featuring an in-ground pool surrounded by vibrant, mature plantings. Fabulous library, gleaming hardwoods, and whole house H2O filtration. The unfinished basement contains the tenants' laundry area, storage, and mechanical systems. Freshened garage is wired for EV station (charger doesn't convey). Conveniently located, near downtown with easy highway access, just one mile from the Pawtucket/Central Falls MBTA commuter rail station. The taxes reflect $1,455.00 annual savings due to owner-occupied, historic property tax exemption.
