Welcome Home to 31 Cullinan Drive – A Rare Gem in a Prime Location! Tucked away at the end of a peaceful street in the sought-after West Riding & Diamond Courts community, this 4-bedroom, 3.5-bath home sits on a premium lot just shy of a ¼ acre—offering space, privacy, and charm. Enjoy your morning coffee or evening wind-down on the screened-in back porch, a serene space overlooking the fenced backyard with lush privacy landscaping, adjacent to a quiet greenspace. Inside and outside, the home has been freshly painted, providing the next owner with a palette to customize to their liking. Move right in, though! Key updates include: Newer roof with architectural shingles, updated windows on the main and upper levels, and a Carrier HVAC system (2013). The second garage bay was added by the current owner along with the fabulous screened-in porch. The cozy lower level features a charming brick hearth fireplace, ideal for family movie nights and games. With four generous bedrooms upstairs—including the primary suite—and multiple living areas throughout, there’s plenty of space to spread out, grow, and thrive. And the location? It simply checks all the boxes. With NO HOA and all the benefits of living within the City of Gaithersburg, you’re walking distance to Diamond Elementary School, Diamond Farm Park, and have access to the Seneca Creek State Park trail system. You're also just minutes from the shops and restaurants of Quince Orchard Plaza and the Kentlands, and a short commute to major employers like NIST, MedImmune/AstraZeneca, Novavax, and more. For commuters, the I-270 interchange, MARC train station, and Shady Grove Metro bus park-and-ride are all within a 10-minute drive. 31 Cullinan Drive is a rare combination of indoor and outdoor space and location—ideal for anyone ready to plant roots. Don’t miss your opportunity to call it home!
