An incredibly maintained and updated stately English Tudor with timeless architectural features in the prestigious Rockville Centre neighborhood of Old Canterbury. Conveniently located near Hewitt Elementary School and the newly renovated lakefront. This home features south facing windows that bring radiant natural light all day long. The interior is designed for modern comforts - spanning three generous bedrooms on the second level and 2.5 beautifully appointed baths. The renovated oversized primary suite features double closets, a soaking tub and custom walk-in tiled shower. This residence perfectly blends old-world character with newly renovated spaces - the expansive Living Room is grounded by a wood-burning fireplace, arched openings, built-in shelves and crown-moldings throughout. The other key features of this home are the den, sun porch and office that features french doors opening directly onto a meticulously landscaped backyard patio with mature, privacy-enhancing plantings. Finally the walk up attic is cleverly outfitted with four built-in twin beds for the comfort of your guests - as well as a finished basement and laundry room.
