Development Management Answers: Does rendering require consent?

One condition of class A, part 1, schedule 2 of the General Permitted Development Order 2015 is that, for an extension or alteration to a dwellinghouse to be permitted development, the materials should be of similar appearance to those used on the existing dwelling.

If a householder wishes to render part of his house, does this mean planning permission would be required if the existing house was built of brick, given that the render would not be of similar appearance? MS

A. If a house is built of brick with no rendering, planning permission would automatically be required to render the existing house or to build an extension with render on it, since a material that is not similar to an existing one on the house is being introduced. This is confirmed by Development Control Practice 12.416. This does not necessarily mean that such a proposal is automatically unacceptable, of course. Rather, it gives the local planning authority the opportunity to consider the scheme and decide whether it is appropriate to grant permission or not. John Harrison
