Glossary of terms - plans and drawings
Crown copyright: the location and block plans submitted with an application must not breach Crown Copyright (eg. they should not be a Land Registry document, a photocopy or a screen grab image). If it appears to us that they do breach Crown Copyright they will not be accepted, the application will be made invalid and replacement plans that comply with Crown Copyright will be requested.
Do not scale: we are unable to accept plans or drawings that state ‘Do Not Scale’ (or similar wording) on them and request that such wording is removed or you let us know, in writing, that for planning purposes we may scale from them. Each plan should have at least one significant measurement on them and a scale bar.
Paper size: plans and drawings should ideally be on A4 or A3 sized paper.
Plan numbers: Give each plan and drawing a unique reference number.
Plan and drawing types
Location plan at a scale of 1:1250 (towns and villages) or 1:2500 (rural) that is based on an up-to-date Ordnance Survey map and which shows:
• the application site area outlined in red (this should include all land necessary to carry out the proposed development eg. land required for access to the site from a public highway, visibility splays, landscaping, car parking and open areas around buildings)
• any other land in the same ownership/ control close to or adjoining the application site outlined in blue
• sufficient roads and / or buildings on land adjoining the application site
• which way is north
• the scale used.
Block plan at a scale of 1:500 or site plan at 1:200 (if the proposal will alter an existing building/structure footprint, or create a new building/structure footprint) that is based on an up-to-date Ordnance Survey map and which shows:
• the proposed development within the context of the existing buildings and structures, the property boundaries and accesses, the road, any public rights of way crossing or adjoining the site and adjacent buildings and structures
• any existing or proposed vehicle parking spaces / areas
• the position of all trees on the site and those on adjacent land – where access is not possible to the adjacent land then the ‘estimated position’ of the trees should be shown
• the extent and type of any hard surfacing
• the location of any existing or proposed drainage
• which way is north
• the scale used
Site levels to a scale of 1:200 (if the proposal will lead to a change in the level of the land) showing existing and proposed ground levels across the site. Measurements should be taken from an ordnance survey data point or from an otherwise authoritative and easily identifiable fixed point. They should also show which way is north and the scale used. These details need to be provided both in plan form and by appropriate cross sections and should cover the land including and beyond any proposed building footprint.
Floor plans to a scale of 1:50 or 1:100 (if the proposal will create, alter or add to a floor) showing:
• the existing and proposed layout of the whole of each floor that will be created, altered or added to by the proposal (unless the proposal is for a single room extension, where a partial floor plan will be acceptable)
• the name of each of the rooms or areas
• the scale used
Elevation drawings to a scale of 1:50 or 1:100 (if the proposal will create, alter or add to a building/structure) showing:
• the existing and proposed view of each side (labelled north, south, east or west as appropriate) of the building or structure that will be altered or added to by the proposal
• ground levels
• finished floor levels (unless provided on other plans and drawings)
• where the proposal relates to the conversion of a barn/outbuilding, information about which parts of the original building fabric that will be retained and which parts that will comprise new build
• the scale used
Elevation drawings contextual to a scale of 1:50 or 1:100 (if the proposal will create a building/structure) showing the proposed elevations in context with any immediately adjoining/neighbouring buildings. These should include the datum level, ground level, floor levels for the proposed building, which way is north and the scale used.
Cross section drawings
• If the proposal will create, alter or add to a building – cross section(s) through the existing (if any) and proposed building and the remainder of the site relating these to adjoining ground levels. These should be to a scale of 1:50 or 1:100 and show the scale used.
• If the proposal is for a track or an outdoor horse-riding arena – cross section(s) of any proposed surface treatment, which should include details of the proposed surfacing materials. This should be to a scale of 1:10 or 1:20 and show the scale used.
• If the proposal relates to a listed building – whole vertical and horizontal cross sections showing joinery details, profiles and sections for new or replacement doors and windows and other architectural features. This should be to a scale of 1:2 or 1:5 and show the scale used.
Roof plans to a scale of 1:50 or 1:100 (if the proposal will alter the roof) showing the existing and proposed layout of the roof structure (eg. position and type of roof trusses, ridges, purlins etc.).
