Georgian style house in Folkingham, with what appears to be a bricked up central window. Note that the number of windows on the frontage is 6. The window tax of 1696 was levied on houses with ten or more windows. In 1766 this was extended to seven windows and above. The tax was abolished in 1851.
But the tax was levied on all openings, including the rear. So its quite possible this blank window is decorative, not financial.
