About This Home
A rare opportunity in Downtown San Diego’s Marina District—two separate residences thoughtfully combined to create one expansive 4-bedroom home with exceptional flexibility. Unlike a traditional condo, this unique property offers multiple private hallway entrances, allowing portions of the residence to function independently while remaining connected. With only one neighboring residence on the floor, the home offers an added level of privacy that is difficult to find downtown. Enjoy the entire space as one impressive residence, create a private executive home office separate from your living area, or accommodate extended family and guests with added privacy. Two dedicated parking spaces provide valuable convenience in the heart of downtown. Located in the Marina District, just moments from the waterfront, Gaslamp Quarter, dining, entertainment and the Embarcadero, the home is positioned within one of downtown San Diego’s most established neighborhoods. The surrounding waterfront continues to evolve, with ongoing and planned development expected to further enhance connectivity, amenities and the overall waterfront experience. The City’s Downtown Community Plan specifically identifies the Marina area as benefiting from future waterfront development, improved connections to the bay and additional neighborhood-serving amenities.
