Summary of Case (appeal
The property is a two-storey
semi-detached house, and the application included a proposed rear dormer.
The key issue was whether the
use of felt for the flat roof of the proposed rear dormer would be contrary to Class B, part B.2(a), which
requires that “the materials used in any exterior work shall be of a similar appearance to those used in the
construction of the exterior of the existing dwellinghouse”.
The Inspector stated the
“The condition requires
that external materials used shall be of similar appearance to those of the exterior of the existing
dwellinghouse. This does not require, therefore, that they have to be of the same type, or even that they match,
rather it must mean that factors such as visibility and overall effect on the appearance of the house when the
development has been undertaken are relevant”.
"As for the felt roof,
this would not be visible from any public viewpoint, and most probably in any private view, because of the
height of the dormer, and its proximity to the ridge of the house. The use of felt, or any other
material, on the flat roof would have no impact whatsoever on the appearance of the existing dwellinghouse, as
it could not be seen. I therefore conclude that the materials that would be visible would be likely to be of a
similar appearance to those used in the construction of the exterior of the existing dwelling and, to that
extent, the condition in question is likely to be met.”
The use of felt (or similar) for
the flat roof of a dormer (assuming that the visibility of the roof would be limited) would not be
contrary to Class B, part B.2(a). The Inspector indicates (or implies) that the felt would not need to
have a similar colour to the materials on the existing house.
