Planning Applications - Requirements for drawings, plans, photos & certificates

This list of requirements, for any drawings, plans & certificates which may have to accompany your planning application, will help you to avoid some of the more common mistakes and reduce the risk of unnecessary delays.

The Planning Portal This link opens in a new browser windowDrawings and plans submitted via the Planning Portal as part of a planning application.

It is now possible for members of the public and planning professionals to submit an entire Planning Application, including plans and drawings online, using the Planning Portal.

However the following restrictions and requirements apply regarding the file size and scale of any plans or drawings which are to be submitted online to the Planning Portal.

File size - restrictions on the size of files containing plans & drawings to be submitted via the Planning Portal:

  • Please note that individual computer files containing plans and/or drawings must not exceed 5MB (5 megabytes) in size.
  • In addition the combined file size of a group of files containing plans and/or drawings must not exceed 25MB (25 megabytes) in size.

Scale of plans and drawings.

  • Before submitting any drawings and/or plans online to the Planning Portal, please make sure that original plan/drawing size (for example A3, A2 etc.), is either marked on the plan or drawing or stated within the accompanying correspondence.


Drawings, if required, are probably the most important part of any planning application.

They enable planning officers and Members of the Council to fully understand what it is that you are proposing

They are also used when we consult local people about your proposal. It is therefore vital that they are clear and accurate.

They often need to show more than just your property or what you want to do. This is because whether your application is acceptable or not may depend on how the rest of the building(s) or land is used or looks.

The relationship of your proposals to surrounding buildings may also be important.

The following requirements generally apply:

  1. A Location Plan - ALWAYS REQUIRED
    Preferably at a scale of 1:1250. The site should be clearly identified by a red line around the boundary. A blue line around the boundary should identify any other land owned by the applicant.
  2. A Block Plan
    A more detailed plan at a scale of 1:500 or 1:200 showing 1) the application site, 2) immediately adjacent properties and 3) proposed works the subject of the planning application

Notes on Detailed Drawings

Accurate scale drawings should accompany all applications.

These should be at scale of at least 1:100.

Drawings at a smaller scale (1:200 or 1:500) will only be accepted where this is necessary due to the size of the building or the extent of the land involved in the planning application.

A useful rule of thumb as to when smaller scale drawings would be acceptable is where elevations or floor plans at 1:500 would not be able to fit onto A1 size drawing paper.

In any case smaller scale drawings would also need to be accompanied by drawings of details at a scale of at least 1:100.

It is helpful to include Drawings and plans of the existing and proposed situation

Drawings should normally show the whole of the property.

It may also be necessary to see the proposal in relation to neighbouring buildings and it can often be helpful if a 'street scene' elevation is included.

All drawing should be given a unique number e.g. 1.1, 1.2, 1.3 etc. This helps to identify precise drawings.

Any revisions to drawings should be clearly identified with a new number and date of revision (e.g. 1.1a, 1.2b, 1.3c etc.)

Annotated details of the specific revision should also be given on the plan - usually in the bottom right hand corner.

All drawings should have a title, e.g. "Proposed first floor plan" or "existing front elevation" etc.

Typical Drawing Requirements

1. Proposals for a conversion or a change of use only i.e. where no external works are proposed, should normally only require the following:

  • Existing and proposed floor plan

2. Where simple changes to the external appearance of the property are proposed, like putting in new windows, the following will be needed:

  • Existing and proposed elevations of all faces that are to be affected.

3. Where extensions are proposed to buildings, the following will be needed:

  • Existing and proposed floor plans of all the floors of the building affected by the proposals.
  • Existing and proposed elevations of the whole building showing the front, side and rear elevations
  • Existing and proposed roof plans
  • Existing and proposed sections through the extension and the rest of the building


Photographs can be very helpful. They are not essential, but if sent, they may give officers a better understanding of the proposals before they visit the site.


The law requires that anyone who has an 'interest' in the application site should be notified in writing by you 21 days before you submit the application.

The method for doing this is set out at the end of the application forms.

If you do need to notify anyone, use Schedule 2 and complete Certificate Bat the end of the application form.

An 'interest' means a freeholder or anyone who has a lease or a tenancy of seven years or more.

For example, if you own a flat in a converted house or building you should notify the freeholder(s) that you are submitting an application.

You should also notify the occupants, leaseholder and/or freeholders of the other flats in the building if they have a lease or tenancy of seven years or more.

If you are the sole owner and occupier of the building then you should just complete certificate A.

N.B. If you are unable to identify and/or notify any or all of those with an 'interest' you should complete copies of Certificates C and D and Schedule 2 which needs to be published in a local paper.

These rules may appear cumbersome but they are a legal requirement and relatively straightforward if you follow the instructions.

Please seek help from Planning Services if you are not sure how to proceed. We appreciate that the application process can be complicated.

We will be happy to help you.
