Long before mid-century modern became a catchphrase, early modernists were blazing trails with creative concepts. Such is the case with this unique four-bedroom, 3.5-bath home at 2921 Argyle Drive in Alexandria s Monticello Park neighborhood. Built in 1941 and designed by renowned DC architect Joseph Abel, the International-style house displays cubist principles, four levels, a bold chimney and ribbon grids of double-pane windows. Nestled into the end of a quiet cul-de-sac, this striking white brick and wood house is tucked behind mature leafy trees. There are plenty of parking spaces out front and wide steps leading down to a covered entryway. A new red door with frosted glass panels opens to a charming foyer with multicolored slate flooring and a storage bench. This leads into a open living and dining space with wood-burning fireplace and wide windows indicative of the modern era. Hardwood floors run throughout the house, offering ease and consistency. A beautifully remodeled white-on-white kitchen remains faithful to the original layout while adding Bosch and GE Cafe stainless steel appliances, granite counters and an abundance of efficient storage. The windows in the kitchen and throughout the house invite the outdoors in! A powder room is on the main level, as well as front-loading washer and dryer and a door leading to a beautiful deck overlooking the backyard. Stairs lead up to the second level with a lovely master bedroom suite with full bath and walk in cedar closet. Also on this level is a large family room with a second fireplace as well as a sunroom with wood paneling, tile flooring and a wraparound grid of windows. The top floor features three more bedrooms with contemporary ceiling fans and two full baths. If all that isn t enough, the unfinished basement currently is home to a ping pong table, workshop and additional storage space. The lush yard, featuring patio, perennials and stone-terraced landscaping is surrounded by a fringe of trees and bamboo for maximum privacy. Summer nights are magical here! From its rich architecture to numerous updates, this showcase residence is not only a time capsule of seminal modern design, but an inviting place to live.
