In Waban, where stately Colonials define the streetscape, new construction has to do more than look good. It has to belong. At 873 Chestnut Street, a newly completed home by Arco Design + Build manages to fit in with the neighbors while delivering something undeniably modern.

From the curb, the five-bedroom residence reads as a classic New England Colonial, symmetrical and composed. Inside, the traditional front rooms offer a formal dining room, private office and fireplaced family room. Then the layout opens wide. Along the rear, a bright, expansive kitchen, living and dining area stretches toward serene pond views out back. Custom cabinetry, Monogram appliances, quartz counters and a waterfall island anchor the space, with walls of glass and a deck extending the entertaining footprint outdoors.

Spanning more than 6,300 square feet, the home includes a vaulted primary suite with two oversized walk-in closets, a spa-style bath with steam shower, soaking tub and heated floors, plus a private balcony overlooking the water. Three additional en-suite bedrooms and a fully finished walk-out lower level with guest space and flexible rooms complete the offering.
