  • Up to date architect's scaled plans/drawings of the property or redevelopment
  • Up to date architect's scaled plans/drawings of any extensions where applicable 
  • Up to date architect's scaled plans/drawings of any 'Rooms in a Roof' - that is, loft spaces
  • Documentation of Wall structure, brickwork, insulation or other external/internal wall finish
  • Documentary evidence of any wall insulation
