Summary of Case (appeal
The property is a two-storey
semi-detached house with a hipped roof. The application was for a
proposed hip-to-gable roof extension and the erection of a 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”.
During the application, the
agent confirmed that felt would be used for the roof of the proposed rear dormer, and the Council refused the
application on this basis. Following this refusal, the agent
proposed red or brown mineral felt as being similar in appearance to the roof tiles, or as an alternative,
The Inspector acknowledged
that the materials incorporated into the external fabric of the house do not include mineral felt. However, she
stated that this in itself would not rule out the use of felt because the condition is for a material of
a similar appearance, not type. The Inspector stated that achieving a similar appearance “could depend on
a number of factors including colour, form, texture, durability, size, profile and visibility”. She noted that any views of the felt would be from a distance, and that the
colour would be the most important discernable characteristic, rather than the texture. The Inspector stated
that the probability is that felt of a colour similar to the existing roofing tiles would be available and so in
effect the felt covering would be of a similar appearance. The Inspector therefore concluded that that Class B,
part B.2(a) could 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 (in
principle) be contrary to Class B, part B.2(a). However, the
Inspector indicates (or implies) that the felt would need to have a similar colour to the materials on
the existing house.
