The one you've been waiting for: a quintessential Chevy Chase charmer on the exterior - and an absolute dazzler on the interior! Deceptively large and having recently undergone a high-end, down-to-the-studs renovation and expansion, 3914 Blackthorn Street now boasts 5-6 bedrooms/5.5 bathrooms, 4 finished levels with nearly 5000 SF feet of stunning living space, and an enhanced 2-car garage. Abundant windows and natural light, high ceilings, impressive millwork, kiln dried white oak flooring, and an ethereal paint palette set an elegant, yet modern tone. Main level highlights include an open floor plan, wonderfully spacious living, dining and gathering rooms, a show-stopping center island kitchen with professional appliances and a to-die-for prep pantry, and an elegant powder room. Upstairs, the second level offers a lovely owners' wing with custom walk-in closets, three additional beautiful ensuite bedrooms, a custom laundry room, and three gorgeous bathrooms, all which feature heated floors, solid marble tile, and quartz countertops. Phenomenal third level offerings include a light-filled family room with a vaulted ceiling and a wet bar, and a fabulous fifth bedroom featuring a sitting/office area, and a full bathroom. Offerings of the home's lower level include a recreation or guest room with an ensuite bath, a large playroom, a beautifully equipped kitchenette with a second washer & dryer and an egress door to the rear, and plenty of built-ins and storage options. Special exterior features include a delightful, covered porch on the front and -out back- a grilling deck with a gas connection, a level fenced yard with lush lawn space and shrubbery, and a carriage-style garage featuring loft storage and a covered exterior area for gardening. Situated on an idyllic sidewalk lined street in the Town of Chevy Chase, this location is superb! {Elementary schools: Rosemary Hills PreK-2nd; Chevy Chase 3rd-5th}
