Planning Guidelines For Side Conservatories or Extensions

Dec 13, 2023 | News

When you’re thinking of building a conservatory or extension at the side of your property we always advise submitting a planning enquiry.

The planning rules for conservatories or side extensions seem reasonably straight forward however local authorities often interpret these same rules differently.

There is a guide to building a conservatory under permitted development at the side of your property on the Planning Portal

To summarize

  • On designated land, perhaps a conservation area or national park a conservatory to the side of the ‘original house’ is not permitted development and would require an application.
  • The ‘original house’ means as it was first built or stood on 1st July 1948.
  • A conservatory at the side must not have a width more than half of the width of the ‘original house’ to be classed as permitted development.
  • Side conservatories must not have a total height exceeding 4m, this is measured from ground level not the conservatory floor level, this also applies to the eaves height if the conservatory is within 2m of a boundary which should be no more than 3m.
