The Mid Century Modern expansion in Carderock you have been waiting for! Absolutely stunning expanded Parkside with nearly 3800 light filled out of ground, renovated sf on a premium level landscaped lot in the quiet heart of the neighborhood. Incredible primary suite expansion with gorgeous spa-like bath, balcony (watch Congressional Country Club fireworks from your retreat!). The quintet of desires fulfilled: family room expansion, primary suite expansion, great lot, quiet part of neighborhood and renovated! On on a beautiful level lot with stunning, professionally landscaped and hardscaped garden. This model already had beautiful oversized bedrooms including the original primary bedroom on the main level which is great for multi-generational living or visiting guests. The house boasts a wonderful open "great room" floor plan for the kitchen, dining and living room spaces, all with vaulted ceilings, which adjoin a family room with wet bar and access to the gorgeous rough hewn flagstone patio overlooking the level and landscaped garden with extensive grassy play area. Wilets/Howes (MCM specialists) designed a two story addition doubling the square footage--adding a family room, sun-filled play/recreation room, laundry room and large mud/storage room on the main level and, upstairs, a magnificent primary suite addition with luxurious, spa-like primary bath (double sinks, soaking tub and large shower), fabulous fitted closets and a large office/exercise room or nursery. This home is renovated beautifully with stylish choices in the kitchen and 3.5 bathrooms, all in keeping with the modern design. The floor plan is versatile and can be used in many ways (including multi-generational living) and all the square footage is out of ground and light-filled. A short walk to the pool/tennis/pickle ball and clubhouse and prized Carderock Springs Elementary (in the sought-after Pyle/Whitman cluster). All this, in a wonderful community so close to shopping and dining in Cabin John, parks, trails, nature, and Glen Echo Park with its classes and camps. EZ commuting to all the DC area has to offer including the bus on River Rd just a half mile away!
