Welcome to a rare mid-century retreat on approximately one-third of an acre, surrounded by the natural beauty of Rock Creek Park. This thoughtfully updated 1958 residence retains the defining architectural elements that make mid-century homes so special—vaulted ceilings, walls of glass, clean lines, and a seamless connection between indoors and out. The main level alone spans more than 2,000 square feet, offering an exceptionally generous footprint that is increasingly difficult to find in Northwest DC. The home features four bedrooms, three full bathrooms, and impressive ceiling heights on both levels, with custom floating staircase. What truly distinguishes this property is its setting, size, and existing home that is perfectly ready to be lived in as is, or can be adjusted with more space and a different footprint.. Along the western edge, the home is embraced by Rock Creek Park and the Valley Trail, creating remarkable privacy and views of mature, old-growth trees. Expansive windows throughout the home bring the surrounding landscape inside and reinforce the home's original mid-century vision. The oversized property also offers tremendous potential outdoors. Reimagine the grounds with terraced landscaping, create a level lawn directly off the patio, and explore the possibility of a pool, sport court, or additional outdoor entertaining spaces on the upper portion of the property. With this much land and privacy, there is an extraordinary opportunity to create a true urban retreat. Immediately adjacent, 1842 and 1844 Primrose are planned as two new luxury residences, creating a distinctive collection of three homes at the edge of Colonial Village—the final three properties in Washington, DC before crossing into Maryland. For an even more compelling opportunity, all three contiguous properties—1840, 1842 and 1844 Primrose—may be purchased together, offering a rare chance to control an exceptional assemblage of land along Rock Creek Park in one of Northwest DC's most beautiful residential settings.
