Property boundaries/buildings in Greater London

Request for information – FOI16701

Request

Thank you for your email of 5 September 2016, requesting the following information in accordance with the Freedom of Information Act (FOIA) 2000:

I hope you may aid my search by providing information within the following criteria:

  • (a) Areas of all property boundaries in greater London.
  • (b) Areas of any building within above boundary, specified in (a).

This information will be invaluable in understanding the construction shifts occurring in London.

I would appreciate to receive the information in electronic format if possible. If you need further clarification, please contact me by email and/or phone.

If my request is denied in whole or in part, I ask that you justify all deletions by reference to specific exemptions of the act. I will also expect you to release all non-exempt material. I reserve the right to appeal your decision to withhold any information or to charge excessive fees.

I would be grateful if you could confirm in writing that you have received this request. I look forward to your response within 20 working days, as outlined by the statute.

Our response

I regret to inform you that Ordnance Survey is unable to help you with your enquiry as we do not hold this information as Ordnance Survey does not depict or maintain legal property boundaries; this is the remit of Land Registry.

Ordnance Survey only maps the existence of physical features on the ground at the time of survey, which are within our specification and published tolerances. For more information about property boundaries (legal, physical and general boundaries) and who is responsible for recording them, please see our joint statement with Land Registry regarding property boundaries on our property boundaries web page.

Under our duty to provide advice and assistance as stipulated in Section 16 of the FOIA, we can provide you with the following information which may assist you in this matter.

  • a) The information that you have requested in part (a) is available as open data from Land Registry and can be found by Local Authority extent at on the gov.uk website.
  • b) We are not able to give information specifically about buildings within the property boundaries as we cannot use our data to determine which buildings fall within each property boundary. However, Ordnance Survey produces OS OpenMap – Local, available on our OpenData ordering page which has detailed but generalised building extents which could be combined with the Land Registry index polygons, referred to in (a) above, in any applicable GIS software package to give a view of the building area within each Land Registry index polygon.

If you require more detailed building areas, including out buildings then the Ordnance Survey product OS MasterMap Topography Layer provides this, however, please note that this is a premium product.

I hope the above information is helpful to you.
