DO YOU NEED PLANNING PERMISSION FOR A CONSERVATORY.

1. The type of property extending from e.g. a detached, semi-detached or terraced house (note; flats do not have any automatic right to have a conservatory or extension).
  • A detached or semi detached house can add up to 70 cubic metres or 15% of its volume up to a maximum of 115 cubic metres.

  • A terraced property can add up to 50 cubic metres or 10% of the existing house volume up to a maximum of 115 cubic metres
(Note Scotland has slightly different regulations)

2. Has the property had building work involving extending it in the past. If so the size of the previous extension must be subtracted from the total that is available for your type of property.

3. Is your property listed or in a conservation area? If so you must seek planning permission before any kind of work is considered.

4. There are properties that already have there automatic planning permission rights removed, if yours is one you do need to seek advice before any building takes place.

5. If the proposed conservatory is more than 4m high in any place then it cannot be extended within 2m of any property boundaries (this would infringe on the rights of your neighbours).

6. The conservatory cannot cover more than 50% of the size of your garden.

If you have any questions or queries regarding planning permission it is always wise to contact your local planning authority.

DO YOU NEED TO FOLLOW BUILDING REGULATIONS.

You do not need to follow building regulations for a conservatory as long as you meet the following requirements:
  • It has an area of less than 30 square metres.
  • Any radiators in the conservatory must be thermostatically controlled.
  • The conservatory can be closed off from the main house.
  • The conservatory walls should be more than 75% glazed.
  • Any glazing in the conservatory must satisfy safety regulations for breakage.
  • The conservatory must have a transparent or translucent roof.
  • The conservatory is situated at ground level.
Again if there are any questions or queries always contact your local planning authority.
