Located at the intersection of St. Mary's Street and Convent Street.SVN | Traditions is pleased to present a rare downtown San Antonio redevelopment opportunity! This offering includes two architecturally significant buildings—The Flats and The Voss Building—both showcasing Spanish Colonial Revival design with ornate Churrigueresque detailing.

The Voss is a two-story commercial building of substantial construction, offering the unique opportunity to activate its rooftop as an amenity space.

Envisioned by many as an ideal setting for an upscale restaurant, bar, club, or retail concept, it also lends itself well to creative office use.

This feature provides convenient ingress and egress along with dedicated parking opportunities—an exceptional advantage in the heart of downtown San Antonio.
