Set back from the road on an estate lot on the desirable East Side of Westborough, this well-maintained Colonial offers 10 rooms, five bedrooms, and 5.25 cleared acres with equestrian potential. A heated 20-by-40-foot in-ground pool, two-car attached garage, and separate three-car detached garage make this property especially appealing for car enthusiasts, hobbyists, or those seeking extra space. Inside, hardwood floors extend throughout much of the home. The cherry cabinet kitchen features a center island, granite countertops, stainless steel appliances, and a separate dining area overlooking the expansive sun deck. Open to the kitchen, the cathedral-ceiling family room with a fireplace creates an inviting space for everyday living and entertaining. A formal dining room, private living room, home office, and half bathroom complete the first floor. Upstairs, the spacious primary suite includes vaulted ceilings and an updated bathroom with a double vanity with quartz countertops, a ceramic-tile shower, soaking tub, and tiled floors. Four additional bedrooms and a convenient second-floor laundry room complete this level. A walk-up attic provides excellent storage and future flexibility.
