4914 Upton St NW is a timeless 5 Bedroom and 4.5 Bath Colonial that was beautifully renovated and seamlessly expanded in partnership with Jim Gibson Builders and GTM Architects. Spanning approximately 5,400 square feet and perfectly situated on an expansive 1/4 acre lot in Spring Valley, this lovely residence showcases a backyard oasis that includes two patios, a rear deck, and a level green space. Gleaming hardwoods, Niermann Weeks lighting, luxurious plantation shutters, custom millwork, and thoughtful lifestyle additions make this impressive residence a home built for generations to come. An attached and heated 2-Car Garage is complete with a custom enamel finished concrete floor, additional covered parking for two, and a large driveway that runs the length of the home offers ample and discreet off-street parking. The charming front porch and a one-of-a-kind mahogany front door with custom cut glass opens to the Foyer that is flanked by the formal entertaining spaces. A cherished landmark of the Foyer is the original 1935 Tiger Maple banister on center hall front stairs. An intimate Living Room shares a two-sided gas fireplace with the stunning Great Room that has been adorned with built-ins and an eye-catching coffered ceiling. The two Main Level fireplaces have been dressed with exquisite vanilla onyx surrounds. The Gourmet Kitchen has access to the side Patio and is outfitted with custom cabinetry, granite counters, and Thermador appliances. The adjoining Dining Room is highlighted by a Niermann Weeks chandelier and a built-in china cabinet. With views overlooking the backyard, the Family Room is flushed with a wonderful southern exposure and finished with custom built-ins and a fireplace. The Breakfast Room is adjacent to the Family Room and Kitchen and opens to the rear Deck that has stairs leading down to the backyard. There are 4 Bedrooms and 3 Full Baths on the Upper Level, including a gorgeous Primary Suite. The Primary Bedroom showcases a soaring vaulted ceiling, a fireplace, walk-in closet, and a Primary Bath that was recently renovated. The Primary Bath was updated to include heated floors, a humidity sensing ventilation system, a premium soaking tub, and a dual vanity. Bedroom #2 is a private suite with an attached marble bath. The two additional Bedrooms on the Upper Level share a third Full Bath with closets (one cedar lined) and custom plantation shutters. The Upper Level is complete with an Office/Sitting Room that boasts custom built-in desks and access to the Laundry Room. The Lower Level is a fabulous entertaining space with a Recreation Room, 450-bottle climate-controlled glass-front wine room, a second Full Kitchen with a wine refrigerator, an Office Space with built-in desks, an Exercise Room/5th Bedroom, and a Full Bath that was updated in 2018. Heated floors warm the Kitchen and Full Bath. Large closets (one of them cedar) offer additional storage and room for organization. There is a spacious floored stand-up insulated storage attic running the width of the house with pull down center hall stairs.
