Offering the utmost in flexibility, this centrally located, renovated, expanded, and meticulously maintained, Colonial offers opportunities for live/work, extended family, au pair, and/or rental possibilities. The original section gleams with the original architectural charm and craftsmanship, while examples of today's modern conveniences are showcased throughout, including the large eat-in kitchen with top-notch appliances and granite. Sliders open to a huge deck and a private backyard bordering conservation land that must be seen to be appreciated. A newer section of the home includes an office/study and connects to a three-car garage. Upstairs is the truly dramatic great room, with huge windows overlooking unbuildable woodlands, a gas fireplace, a separate kitchenette/set bar, and vaulted ceilings. This connects to the master with en suite bath, and the rest of the second floor. The walk-out lower level is finished as a separate three-bedroom, 1,708 s.f. apartment. Full house wifi.
