Welcome to 34 Mountain Avenue! Perched above the street, this sunny and solidly built Tudor Revival house with special architectural features beckons. A spacious entrance hall leads, on one side, to a step-down, expansive living room with soaring 10-ft ceilings and gorgeous crown molding, a granite wood-burning fireplace, and French doors opening to a stone terrace. On the other side is a graciously appointed dining room with armorial stained-and-leaded-glass casement windows. Beyond is a stunning kitchen, gut-renovated in 2022/2023, featuring Wolf, Bosch, and Viking stainless-steel appliances, radiant-heated marble floors, custom cabinetry, and a custom-designed stainless steel hood. Rounding out the first floor is a bedroom/office with ensuite full bath (perfect for nanny/au pair), a cozy wood-paneled library with garden views and a French door to the back lawn, and a charming vintage celadon green-tiled powder room. The star of the second floor is a notably oversized primary bedroom with a lofty tray ceiling and gut-renovated primary bathroom, just completed in September 2024! Waterworks fixtures, a steam shower with marble bench, tub with luxurious marble deck and crystal-handle faucet set, a vanity with a matching crystal-handle faucet set and marble slab counter, and radiant-heated marble tile floor. Make this airy, light-filled primary suite your private sanctuary and spa! Also on the second floor are three generously-sized family bedrooms and an updated hall bath with marble-topped vanity and tub/shower. The first bedroom has an arched nook with window seat and a large walk-in closet. The second bedroom has a wall of built-in bookcases and a walk-in closet. The third bedroom has two standard-sized closets and built-in bookcases, plus an arched nook with two small storage closets. The lower level features a spacious family room, laundry, storage/utility room, a half-bath, and access to the garage. The flat, level backyard includes a fenced area. An easy walk to train and Murray Avenue School. Make this your forever home!
