Class A of the GPDO 2015 sets out rights for 'The enlargement, improvement or other alteration of a dwellinghouse'
This subject to restrictions and conditions, one of the conditions being:
A.3 Development is permitted by Class A subject to the following conditions— (a) the materials used in any exterior work (other than materials used in the construction of a conservatory) must be of a similar appearance to those used in the construction of the exterior of the existing dwellinghouse;
The term 'similar appearance' is open to interpretation but the Government Technical Guidance provides some clarification:
The condition above is intended to ensure that any works to enlarge, alter or improve a house result in an appearance that minimises visual impact and is sympathetic to existing development. This means that the materials used should be of similar visual appearance to those in the existing house, but does not mean that they need to be the same materials. For example:
• the external walls of an extension should be constructed of materials that provide a similar visual appearance - for example in terms of colour and style of brick used - to the materials used in existing house walls
• a pitched roof on an extension should be clad in tiles that give a similar visual appearance to those used on the existing house roof. Again, colour and style will be important considerations; flat roofs will not normally have any visual impact and so the need for materials of similar appearance should not apply
• it may be appropriate to include new PVC double glazed windows in an extension even if there are no such windows in the existing house. What is important is that they give a similar visual appearance to those in the existing house, for example in terms of their overall shape, and the colour and size of the frames. This condition does not apply to conservatories.
The section on extensions to brick faced dwellings confirms that the extension would have to be brick faced, no other material would be acceptable.
This leads me to conclude that rendering a brick faced building would not comply with this condition and would therefore need permission.
If there are any alternative interpretations or relevant appeal decisions out their I would welcome the input!
