DC Casebook: Householder development - Meaning of similar materials considered

An inspector has issued a lawful development certificate for a roof extension to a semi-detached house in south London after finding that the materials would be similar to the existing dwelling.

The appellant sought permission for side and rear dormer extensions to facilitate a loft conversion. He argued that the proposal was permitted development under class B, part 1, schedule 2 of the General Permitted Development Order 1995 as amended. The council took the view that the extension failed the test in class B.2(a) because the brickwork on the flank elevation was not similar in appearance to the blue roof tiling.

The inspector considered that recent technical guidance issued by the DCLG resolved the dispute. This states that the condition is intended to ensure that any alteration to a roof for a loft conversion minimises visual impact and is sympathetic to the existing house. This does not mean that the materials have to be an exact match, he reasoned.
