San Antonio's City Hall is easy to miss. It doesn't sit in either of the city's main public plazas (Alamo or Main) and it is surrounded by mature heritage oak tress. You could drive by it and be completely unaware that the seat of government for America's seventh largest city is located but a few feet away.
The building has other issues as well: the lobby is too small to comfortably accommodate the metal detectors such buildings require and its elevated main floor necessitates visitors in wheelchairs to follow a circuitous path to get into the building. It was this latter issue that inspired Councilman Roberto Treviño to partner with the San Antonio chapter of the American Institute of Architects to hold a design competition to come up with a solution to make San Antonio City Hall more accessible.
Our solution didn't win but we're still proud of it. We proposed an act of "invasive preservation" where in order to restore the presence of a piece of historic architecture we actually call for its physical modification. In historic preservation circles that represents a pretty radical notion, but one of the great things about competitions is that they give you the opportunity to safely explore such ideas since they will probably never actually be built.
At any rate, our entry called for the 1927 entry arch - the most defining characteristic of current version of the building - to be physically removed from the façade and relocated fifty feet to the east. By transforming the existing building’s entry arch into a freestanding “Tricentennial Arch” San Antonio’s City Hall would achieve a civic presence appropriate for a city of its size. The space in between the existing façade and the relocated entry arch would then be filled with a series of ramps and landings to provide access to those in wheelchairs while also creating a platform for civic activities. Press conferences, public announcements and civil protests would have an appropriate stage on which to occur.
