Would you need planning permission to convert a loft into a bedroom and bathroom? No dormer windows are installed, but 4 sky lights in the roof?

Info I've google seems to be very if, but, when, maybe.....
 
On top of my head, I think so, as you are converting a previously uninhabited space to one that is.

I have a "dummy's guide" which would help but it's saved at work.
 
Not sure if planning permission is needed if there's no major alterations but you would need it regulated by the council for usage as a bedroom afaik, although some people just don't inform them ;)
 
I *think* it's fine, BUT if you come to sell you can't claim it as an inhabitable space without. So you wouldn't be adding any 'value' to the property.
 
You definitely need building regulation because of the bathroom, definitely cannot put windows on the front of the property without planning, but should be able to at the rear without. You will need a full set of Architect plans.

It really depends on the size of the works due to the 2008 new permitted development rules you can do extension works up to a certain size without planning, the planning portal will give a volume for these works.

Velux windows can be tricky, generally they can be done under permitted development as they hold no issues of over looking and run flush with the roof slope but there are rules that require them to have planning permission such as if they protrude/create volume the building is listed or within a conservation area or AOONB.

My recommendation would be to talk to your local authority planning officer as they will be able to offer a definitive answer.

If your putting new windows in even velux that overlook someone elses property you will almost deffinatly be better off getting planning permission even if its not 100% required for the specific case. There are also regulations for converting a loft space to habitable especially fire regs.
 
Your loft floor beams may not have been designed for habitable loading, so a structural engineer's input will be needed.
