East Riding of Yorkshire Council

Plans and drawings required for a householder planning application

If you are comfortable drawing your own plans, you can do so. Please note however, if they are incorrect, this will delay the planning process.

If you don't wish to draw your own plans you should instruct a plan drawer or architect to do these for you.

Please note: The council cannot recommend specific agents to draw plans for you, but your builder will probably be able to recommend one for you, or you can find one through a search engine or telephone directory under 'architects' or 'architectural services'.

Location Plan

You must provide a location plan based on an up to date map at a scale of 1:1000 or 1:1250 or 1:2500, (an Ordnance Survey Base Map is preferred):

  • The plan should show named roads (at least two are preferred to identify the location, but if other features are present, eg railway lines or public buildings, then a single road may suffice), and, where they exist, surrounding buildings. 

  • It should also have on it a clearly marked north point and the scale to which it is drawn. 

  • The adjacent properties shown should be suitably numbered or named to ensure that the exact location of the application site is clear. You may need to provide an additional plan of a larger area if your house is in a remote location without clearly identifiable nearby features.

  • You must draw a red line around the application site to define it. Normally this will be the boundary of your house and garden, but if the house is served by a private drive from the highway then this should be included in the red edge up to the public highway.  If your proposed extension is onto land currently in another person’s ownership the red line must include all the required land even if it is separately owned (in which case you will need to serve formal notice on the owner and submit Certificate B).

  • You must also draw a blue line around any other land you own, eg a paddock or field adjoining or close to the application site.

Site plan

You must submit a site plan (also sometimes described as a block plan) at a scale of 1:500, 1:200 or 1:100. The plan must accurately show:

  • The direction of North and the scale of the plan.

  • The proposed development site in relation to the existing building, site boundaries and any other existing buildings on the site.

  • The position of buildings on land adjoining the site should be included to a degree sufficient to make clear the relationship of the proposed development to the existing neighbouring properties. (This element of the plan may be based on Ordnance Survey information, but should be adjusted to show any significant changes - for example an extension on a neighbouring property that brings it closer to the application site). 

  • Any public rights of way or water course crossing or adjoining the site.

  • The position and crown spread of all trees must be shown on the plan where construction operations1 are within a distance of 15metres from the trunk of a tree. This includes trees within or adjacent to the application site.  If you consider that your proposal will not affect any trees within this distance, please indicate this.

  • The extent and type of any proposed hard surfacing including parking and access roads where this is part of your proposal.

  • Details of existing and any proposed new boundary treatment (with a note of heights) including walls or fencing

  • Planting and landscaping proposals if relevant

  • It is helpful to include key dimensions, such as length, width and height of new buildings, heights to main windows and distances between new works and site boundaries, but these should supplement, not replace, an accurately scaled plan.

Existing and proposed floor plans

You must submit drawings to a scale of 1:50 or 1:100:

  • You must show all floors of the proposed development, including attics and basements

  • Where existing buildings or structures are being altered or extended, you may limit the extent of the floor plans to the new work and the immediately adjacent existing accommodation so long as you clearly distinguish between existing and proposed floor plans. 

  • Your drawings should clearly indicate where existing buildings, parts of buildings, other structures and/or individual walls are to be demolished.  (N.B. if your application is for a “granny annex” full floor plans must be submitted.)

The drawings should be sufficient to illustrate the proposal in detail. 



Existing and proposed elevations


Your elevations should be drawn to a scale of 1:50 or 1:100:


  • Where alterations to an existing building are proposed, your drawings must show both existing and proposed elevations and must clearly distinguish between the two. 

  • If your proposal is for a new outbuilding or garage, drawings of all elevations should be provided including any blank elevations.  

  • You must indicate the proposed building materials (particularly where a mixture of materials is proposed) and detail the style, materials and openings of all windows and doors.


You are advised to check closely that the elevations are consistent with the floor plans before submission.


Existing and proposed site sections and finished floor and site levels


For house extensions it will normally be unnecessary to provide levels or cross sections, unless the extension is to be built to a different finished floor level or extends out over a significant fall in the existing ground level. Where there is a change in levels of more than 0.5 metres (including where proposals excavate 0.5m as well as any increase) you must provide:


  • An illustrative drawing(s) to show both existing and finished levels. These should include details of foundations and eaves and clearly demonstrate that there will be no encroachment onto land outside the application site.


  • Plan(s) to demonstrate how the proposed development relates to existing site levels and neighbouring development.  This should show existing site levels and finished floor levels (with levels related to an ordnance datum point off site) and also show levels in relation to adjoining land or buildings.


Cross-section(s) through the proposed works may be required where changes in levels will directly affect neighbouring properties and land. The cross-section(s) should be drawn to the same scale as the elevations.


In cases where roof lights are proposed, a cross-section should be provided to illustrate their position in relation to existing or proposed floor levels.


Roof plans


Where the roof construction is complex a roof plan should be included in the plans. This can be at a smaller scale than the floor plans and elevation drawings, but should not normally be less than 1:200:


  • Your drawings should clearly show the shape of the proposed roof (identifying changes from its existing shape where appropriate by providing existing and proposed versions)

  • They should include details of materials and the location and design of chimneys, vents and any other features consistent with the submitted elevations.
