Planning document information

Description 

Floor plans show the relationship between rooms, space and other features such as walls, windows and doors in each storey of a building. 

Existing and proposed floor plans are both needed for replacement or altered buildings unless the proposed development would not change the floor plan. For example, re-roofing or replacement windows. 

Guidance 

The floor plan drawings you submit as part of your application must: 

  • be drawn to an appropriate metric scale for example, 1:50 or 1:100 
  • show clearly the proposed openings to match with the elevations 
  • show details of existing buildings where relevant, in relation to proposed buildings 
  • show clearly any walls or buildings that are being demolished 

View our example plans for more details

If your application is for change of use where internal alterations are proposed the floor plans must show the existing and proposed layout of rooms. 

You can find more details of what you need to submit in our guidance on sample drawings.
