City's Backside

While the front elevations of Georgian streets are all strictly symetrical things change at the back. This is because when a new street or crescent was designed each purchaser bought a certain length of the façade, and then employed their own architect to build a house to their own specifications behind it; hence what appears to be two houses is sometimes one. This system of town planning is betrayed at the rear of several classical streets: while the front is completely uniform, the rear is a mixture of differing roof heights, juxtapositions and fenestration. This "Queen Anne fronts and Mary-Anne backs" architecture occurs repeatedly in Bath.
