Rarely does a home of this scale and distinction become available. Situated on a quiet, wide residential street just minutes from the city, this magnificent Colonial twin flawlessly combines timeless early 20th-century craftsmanship with premium, top-to-bottom contemporary upgrades. Spanning three finished levels and just about 3,000 square feet of living space, every inch of this 5-bedroom, 3.5-bathroom residence has been thoughtfully improved with high-end fixtures. An inviting wrap-around porch leads inside to a sun-drenched main level featuring hardwood floors, designer lighting, a convenient guest powder room, and a functional entry area with a built-in storage bench. The expansive living room centers around a cozy fireplace, seamlessly transitioning into a formal dining room flanked by original built-in china cabinets, a bright den, and a true chef’s eat-in kitchen boasting 42-inch premium cabinets, elegant granite countertops, a central island, stainless steel appliances, and ceramic tile flooring. The second floor hosts a palatial primary suite serving as a private oasis, complete with a massive walk-in closet and a spa-like en-suite bathroom featuring a deep Jacuzzi whirlpool tub, a separate stall shower, and pristine tile work, alongside an additional generously sized bedroom and full bath. The third floor offers three more bedrooms and a full hallway bathroom, with effortless storage provided by dedicated linen closets and a rare, built-in cedar closet. Set on a massive double-lot footprint encompassing nearly half an acre, the backyard extends beautifully to the tree line, complemented by a private driveway that easily accommodates 8+ vehicles. Mechanically well maintained with dual-zoned central air, gas heating, upgraded electrical and plumbing systems, and a unfinished basement with a good ceiling height with exterior access, this home is walkable to the local park, public transportation, the library, local dining and shopping.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
