Requirement
These should be drawn to a standardised metric scale preferably 1:50 or 1:100, include critical external dimensions (heights/ width/length etc.) and clearly show the proposed works in relation to what is already there.
All sides of the proposal must be shown and these should indicate, where possible, the proposed building materials and the style, materials and finish of windows and doors. Blank elevations must also be included; if only to show that this is in fact the case.
Where a proposed elevation adjoins another building or is in close proximity, the drawings should clearly show the relationship between the buildings, and detail the positions of the openings on each property. It will not be necessary for an applicant to provide detailed information on elevations of existing buildings on the site if these will not be altered by the development proposal.
