Loft Conversion Planning Permission


In many cases you won’t need to get permission at all, but if you want to extend or alter the space in your roof, exceeding specified limits and conditions, you will have to get permission from your local council to carry out the work.

The Specifications

Just to save you some time, you only need to apply for planning permission if your project exceeds the following conditions:

  • A volume allowance of 40 m3 additional roof space for terraced houses*, 50 m3 for detached and semi-detached.
  • No extension beyond the plane of the existing slope of the principal elevation facing the road.
  • No extension to be higher than the highest part of the existing roof.
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms to be added to the roof.
  • Side-facing windows must fitted with obscured glazing.
  • Roof extensions not to be permitted development in designated areas (such as areas of outstanding beauty and conservation areas).
  • Roof extensions, apart from hip to gable, must be set back at least 20cm from the original eaves.
  • The extension cannot overhang the outer facing wall of your house.
  • Getting planning permission for a loft conversion can be a very tricky process. Though it needn’t be. With our own specialists consultants, we know the ins and outs of council law and how these will affect you!

If these apply to your project, or if you think that they might, get in touch and we’ll be happy to help.


We’re more than happy to offer our expertise, so book your consultation today!

    Tim Simmons

    “We couldn’t be happier with the work that Ali and his team have done for us. We had our loft converted to a master bedroom with en-suite and the finish is so good that we’ve had to redecorate the rest of the house as it looked tired in comparison…”

    Excellent Job and Good Service

    Which? Trusted Traders Consumer

    “Building is often fraught with difficulty but we had a very positive and good experience with Central London Lofts. Ali and his team were professional from the outset to the finish. When we needed time to work ideas out, Ali would give us time and advice, some times we took it, some times we forged our own path and then Ali would be supportive…”
