Entrance of old building in Galveston, TX

Galveston is one of the older towns in the state of Texas as such it becomes contingent upon the city government to protect the older homes, office-buildings and churches so that tourists keep coming to the city. During my recent visit to this beach resort town I chanced upon this unique home with no front yard, and an arched entrance. The board above the entrance suggests that this is currently being used as an office/ commercial space.
