This spacious, contemporary 4 bdrm/3.1 bath tri-level has been thoughtfully expanded and added to by its architect/owner and has a fabulous open floor plan that offers tons of flexible space! The downstairs living area has an open kitchen (renovated in 2006) w/SS appliances, newer quartz countertops (2021), huge breakfast bar, buffet open to family room with fireplace, and breakfast table area overlooking the enormous backyard. The great room addition (2004) provides incredible space with more large windows overlooking the oversized lush and private backyard. Current living room would make a wonderful dining room with its proximity to the kitchen, and original beams and mid-century details. The 2 story family room boasts high ceilings with a dramatic floor to ceiling brick fireplace. The second floor has 3 nicely sized bedrooms, including one en-suite, plus a full hall bathroom. The fabulous master suite was part of the addition and encompasses the entire third floor wiith an office nook, 2 sitting areas, bedroom and large bathroom with double vanities, walk-in closets, shower and tub. The primary bedroom has a fantastic view the gorgeous backyard-it's your own private retreat! Other features include: neutral paint throughout, new vinyl wood floors on main level, new roof in 2018. This is a must see home in a fabulous neighbourhood close to Walden School, Deerfield High School, train and town!
