Key Points

When planning a conservatory/single storey rear extension, the key points to think about are

• Site Coverage
  Did you know that you will need planning permission if the proposed conservatory/single storey rear extension (when taken with existing extensions, outbuildings and decking for example), will cover more than 50% of the land around your home?
• Location
  In terms of location, if your property fronts a road and you wish to put an extension closer to that road than the principal elevation, you will need planning permission.
• Height
  Assuming the proposal is only single storey, its maximum height can be no more than 4 metres. Interestingly, if your proposal has an eaves and ridge height greater than that of your property, you will need planning permission. Also, if you are planning on putting an extension within 2 metres of a boundary, the eaves height cannot exceed 3 metres.
• Depth
  If you live in an attached house (say a terraced or semi-detached house for example), the maximum depth you cannot exceed is 3 metres and 4 metres in the case of detached house.
• Veranda
  You will require planning permission if you wished to add a veranda or raised platform to the structure.
• Cladding
  Last but not least, if your house occupies designated land, you cannot clad it. What this means is not entirely clear but we will attempt to interpret this in future articles.
