Welcome to 6408 78th St in Cabin John—a rare opportunity to own a beautifully expanded and remodeled 6BR, 4BA split-level home with 3,644 SF of thoughtfully designed living space in one of Montgomery County’s most desirable and tight-knit communities. Renovated and expanded across all 3 levels in 2015 (adding 1,400+ SF), the home features an open floor plan with a gourmet kitchen, breakfast nook, and living room that opens to a wraparound deck and large, flat backyard. The main level offers 3 bedrooms, including the original ensuite primary bedroom—perfect for flexible one-level living or guest accommodations. The top-level primary suite includes a spa-like bath with soaking tub, dual vanities, and separate shower. All bathrooms, windows, and doors were replaced in 2015. Additional highlights include hardwood floors on the main level and primary suite, a spacious walkout lower level with rec room, two bedrooms, and generous storage. The property also features a 3-car driveway with the potential to fit up to 5 cars—ideal for entertaining or multi-car households. Green energy upgrades include a hybrid water heater with Rheem booster, solar array (10.6 MWh/year), dimmable LED lighting, two EV chargers (Tesla + Level 2), upgraded electrical panel with monitoring system, and a hot water recirculation pump—offering an estimated $2,500/year in utility savings. Bonus features: 2022 LG washer/dryer, surround sound systems and TVs (upper/lower levels), 6 security cameras, water leak sensors with auto shut-off, and a rare bonded membership opportunity at Palisades Swim & Tennis Club (0.5 mi). Walk to local favorites like Fish Taco, Wild Tomato, and the C&O Canal, with easy access to DC, Bethesda, and NOVA.
