Drawing standard – floor plans

Floor plans show the layout of the building.

In most cases, two separate sets of floor plans will be required: ‘existing’ floor plans showing the building as it is now and ‘proposed’ floor plans showing how the building will look, after the works have been carried out.

Floor plans should:

  • show a scale bar or a measured dimension
  • be to a scale of 1:100 or 1:50
  • be clearly annotated existing and proposed
  • show all relevant floor levels of the building(s) being constructed, altered or extended, in relation to the remainder of the building
  • clearly state the use of each room and include position of windows, doors, walls and partitions
  • clearly label each floor
  • clearly label the primary use of each room
  • identify anything to be demolished
