Set on a rare 94 x 140-foot city lot along one of Plymouth’s most admired residential blocks, 377 Arthur Street is a cherished mid-century modern brick ranch, updated with care and designed around natural light, clean lines, and views of the outdoors from nearly every room. With four bedrooms, three-and-a-half baths, a two-car attached garage, and more than 3,500 square feet of finished living space, the home pairs the ease of single-level living with generous gathering spaces, both inside and out. The kitchen, with a view to the rear yard is spectacular, featuring custom natural maple cabinetry, integrated Sub-Zero refrigeration and dishwasher, marble countertops and backsplash, and cleverly concealed storage. Hardwood floors, expansive windows, and open sight-lines fill the main level with warmth and light, and every renovation has stayed true to the original mid-century aesthetic. A 2009 rear addition introduced a spacious primary suite with a separate shower, soaking tub, double vanity, walk-in closet, and brought the laundry to the main level. In 2017-18, the private backyard was transformed into a resort-style retreat: an in-ground heated pool with deck jets (water feature), built-in fire pit, expansive paver terrace, mature landscaping, and a custom cedar privacy fence. The result is sophisticated, secluded, and made for entertaining. The finished lower level adds exceptional flexibility, with a fourth bedroom featuring egress and a full bath, plus a recreation/family room with newer LVP flooring, a home gym, and abundant storage. A new high-efficient furnace was installed in 2026. Architectural character, an oversized lot, thoughtful updates, and outdoor living of this caliber seldom come together in one home. Just a short walk to the shops, restaurants, and parks of Downtown Plymouth, 377 Arthur Street is a home to experience in person.
