The plan for Prior Park was to construct five buildings along three sides of a dodecagon matching the sweep of the head of the valley, with the main building flanked by elongated wings based on designs by Andrea Palladio. The plans were influenced by drawings in "Vitruvius Britannicus" originally made by Colen Campbell for Wanstead House in Essex, which was yet to be built. The main block had 15 bays and each of the wings 17 bays. Between each wing and the main block was a Porte-cochère for coaches to stop under. In addition to the stone from the local quarries, material, including the grand staircase and plasterwork, from the demolished Hunstrete House were used in the construction.
