Outbuildings can often be considered permitted development, not requiring an application for planning permission, provided they meet all the necessary criteria and there are no constraints that restrict or remove permitted development rights. If your intention is to convert a garage into a separate house (regardless of who will occupy it), then planning permission may be required no matter what work is involved.
Planning permission laws for outbuildings apply to sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structure for a purpose incidental to the enjoyment of the dwellinghouse.
Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions:
The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.
It is important to note that permitted development allowances for outbuildings applies to houses but not to flats and maisonettes. All flats and maisonettes will require full planning permission.
If there are any constraints that limit or remove permitted development rights or even one of these criteria is not met, then you are required to submit an application for planning permission.
If planning permission is required but the works are completed without first securing the proper planning approval you may face retrospective planning issues. If the local planning authority determine that planning permission was required an enforcement and or penalties may be issued. If planning permission cannot be secured retrospectively the converted loft may need to be put back to its original state.
