A local planning authority can make a Direction under Article 4 of the Town and Country Planning (General Permitted Development) Order 1995, excluding the application of the Order to a particular property or area.
The effect of this is that the owner of an affected property will not be able to carry out works which would otherwise be Permitted Development without first obtaining planning consent.
Article 4 Directions are commonly applied to Conservation areas.
They are also frequently applied as a planning condition on new housing developments.
This will be revealed on local searches carried out by buyers’ Conveyancing Solicitors.
