Horizons sits between the Gaslamp Quarter and the bay, with the best of both a short walk away. Horizons is a 25-story condominium tower at 510 1st Avenue and 555 Front Street in the Marina District, in Downtown San Diego’s 92101 zip code. Completed in 2001 by Bosa Development, its 211 homes take in city views and sit close to the waterfront and Seaport Village.
Horizons is full-service living done right. A concierge and on-site security look after the building, the pool deck is the place to be on warm afternoons, and residents also share a spa, a fitness center, a BBQ area, a recreation room and a conference room for work-from-home days. Every home includes storage, and up to two pets are welcome.
The Marina District is downtown at its most walkable. The Embarcadero, Seaport Village and the waterfront parks are minutes away on foot, the Convention Center is close by, and the restaurants and nightlife of the Gaslamp Quarter are just a few blocks north. For buyers who want high-rise living with all of downtown within walking distance, Horizons is well worth a look.
