Dorrigo are now able to offer OS site plans for planning applications and other similar requirements. As an Ordnance Survey Licensed Partner we can offer their high-quality Mastermap® Data. 

OS site plan

Whether you’re building a house or an entire housing estate, all planning applications need a map called a ‘Location Plan’ showing the proposal in its surrounding context. Some local authorities might also require a ‘Block Plan’ (sometimes called a site plan) which outlines the development in a larger scale, but not necessarily in greater detail.

Submitting an inaccurate, out-of-date, unlicensed, or incorrectly displayed plan is the most common reason for an application being turned down. Getting it wrong will cost you time and money so there is every reason to get it right first time.

Site Location Plan

  • Should be at an identified standard scale (normally 1:1250 scale for urban applications or 1:2500 for rural or larger applications)
  • The direction of north must be clearly marked
  • The plans should be accurately scaled to fit A4 or A3 paper.
  • Should show the date of survey or an Ordnance Survey licence number if appropriate and the date of purchase
  • Should show enough roads or buildings on the land surrounding your application
  • Should show the application site boundary outlined in red indicating the extent of all land necessary to carry out the proposed development, including the land you need for site access.
  • A blue line should be drawn around any other land owned by you as the applicant, close to or next to the application site.

The Block plan

The Block Plan should again be drawn at an identified standard metric scale (often 1:200 scale or 1:500). It should show the proposed development in relation to the site boundaries and other existing buildings on site with the dimensions specified including those to the boundaries.

It should also show the direction of north and include the following, unless they would not influence or be affected by the proposed development;

  • All buildings, roads and footpaths on land adjoining the site including access arrangements
  • All public rights of way crossing or adjoining the site
  • The position of all trees on the site and those on adjacent land
  • The extent and the type of any hard surfacing
  • The boundary treatment including walls or fencing where this is proposed.

We are confident that the plans that we supply meet the requirements of UK planning departments. If you purchase a plan from Dorrigo and it is rejected by your planning department due to a technical issue with the plan we will rectify the issue for free.

This commitment does not cover plans that are rejected due to not showing the right location, not to the correct scale or not covering the required area. These are things that you can choose at the time of purchase and you should check your local authority's requirements. If you need any help with this please contact us on 0161 775 3737 or
