Impeccably crafted William H. Park Tudor Revival home seamlessly transitioned from a grand single family into a unique, three-unit dwelling. Both smaller apartments are tucked in the rear with a designated tenants' patio affording the lessees and lessor maximum privacy. The primary unit's impressive library was reimagined and painstakingly recreated by the previous owners. Its generously sized kitchen was thoughtfully remodeled, incorporating period cabinetry into a handsomely updated design with chef's stove and butler's pantry. Effortless entertaining flow between the stunning living room, dining room, kitchen and porch leading into the owner's enclosed yard, featuring an in-ground pool surrounded by mature, vibrant plantings. The gorgeous 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. The striking, climate controlled expansion includes a rec room, soundproof exercise / music room, bathroom with radiant heat flooring and infrared sauna, terrific laundry room, and storage. The unfinished basement contains the tenants' laundry area, ample storage, and mechanical systems. Recently 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.
