Dupont Compound - an exceptional offering in the heart of Dupont Circle, featuring a main residence, separate English basement, and a detached carriage house with private parking. A rare combination of scale, architectural significance, and seamless income potential, all set in one of Washington's most iconic locations. First public offering since 1965! The main residence features 2 bedrooms and 2.5 baths, complemented by a legal 1-bedroom, 1-bath English basement apartment, and a detached ADU carriage house with a large private garage and an upper-level studio. The main residence is defined by soaring ceilings and a light-filled open layout, anchored by a chef's kitchen that flows seamlessly to a private rear deck, ideal for elevated indoor-outdoor living. Upstairs, the primary suite captures treetop views and a direct sightline to the iconic Scottish Rite Temple, while a second bedroom and bath offer flexibility and value-add potential. Expansion opportunities remain, with additional buildable space and plans that may convey. The separately metered English basement offers high ceilings, updated finishes, a full kitchen, fireplace, in-unit washer/dryer, and dual access, perfect for refined guest living or income. Completing the offering is the coveted detached carriage house, featuring a private garage and an upper-level studio apartment. Fully self-contained with a kitchen, bath and washer/dryer, providing exceptional privacy and versatility as a guest suite, home office, or premium rental. Both auxiliary units have been consistently leased, delivering strong, reliable income with flexibility for long- or short-term use. 1603 S Street NW offers the perfect blend of location, scale, tranquility and income potential, with room to expand. A rare opportunity to own a true compound in one of DC's most iconic neighborhoods. In a rapidly disappearing category of single-family homes with carriage houses, offerings like this are exceptionally scarce.
