Is Planning Permission Needed For A Loft Conversion?
Usually, a loft conversion is considered by the planning department as a permitted development which means it doesn’t need planning permission. In order for the loft conversion to be considered as permitted development, there are several limits that the construction cannot exceed as well as several conditions which to follow. In terraced houses, a loft conversion doesn’t require planning permission if it creates less than 40 cubic metres of extra roof space. In detached and semi-detached homes, the volume allowance is up to 50 cubic metres. The extension, however, cannot overhand the outer face of the wall.
