Reminiscent of the Spindletop Gusher of 1901, the newly renovated Mobiloil Credit Union Calder Branch features a large oil derrick in the lobby with images of the Spindletop oilfields in the background. The large open lobby highlights the 4,500 s.f. renovation on the first floor of an existing office building on Calder Avenue. The rest of the project accommodates offices, workrooms and a teller area that opens up to the lobby.
