810 Mason Own a piece of San Antonio History! Build a new home, in a historic neighborhood, and get the best of all aspects. Rare opportunity to purchase a vacant lot, in a super central location. Lot has a city street on both sides of the lot, with tons of possibilities with this oversized lot. Build a primary residence that fronts Mason Street and build a secondary residence, or oversized workshop/garage, with access from Glouchester Street. Lots of options with such a large lot, and access from two different streets; all in Government Hill! See survey attached and in photos.
