Will I need planning permission for my loft conversion?
On most occasions with loft conversions Simply Loft can usually carry out the construction phase under permitted development, which does not require planning permission.  The exception to this would be loft conversions to flats and properties in conservation areas.  Also loft conversions that exceed permitted development requirements, which are 40 cubic meters for a loft on a terraced road and 50 cubic meters on a semi detached or detached property will usually have to go through planning permission.

Without planning permission, it usually takes around 2 – 4 weeks to start the construction phase.  This also depends on whether you have party wall agreements in place (if needed) and all structural calculations and plans to hand.  If your property requires planning permission, then it will roughly take anywhere from 8 – 12 weeks before we are able to commence any building work.  Again, you will also need to have any paperwork such as party wall agreements and plans in place prior to commencing.  Certain boroughs in London can be more stringent with planning permission than others.  Our Simply Loft advisors will be able to help guide you on any restrictions or concerns when they visit your property for a site survey.
