Summary of Case (appeal
The property is a two-storey
terrace house. From the appeal decision notice, and from an aerial photo, it appears that the property
originally had a small single storey rear projection, which has subsequently been replaced by a full-width
single storey rear extension. The application was for the proposed replacement of this existing full-width
single storey rear extension with a new full-width single storey rear projection.
The key issue was whether the
proposed extension would be contrary to Class A, part A.1(h), which states that “Development is not permitted by
Class A if … the enlarged part of the dwellinghouse would extend beyond a wall forming a side elevation of the
original dwellinghouse, and would— … (iii) have a width greater than half the width of the original
The Inspector stated the
“The side elevation in
question was the flank wall of an original extension that was demolished some time before the current extension
was built, rather than as part of the same building operation as the construction of the extension. The
Council’s argument is that A.1(h) does not indicate that the relevant wall has still to be in existence to have
a bearing on whether or not an extension would be permitted by Class A.
In my view, it is clear
from the wording of A.1(h) that the relevant wall has to exist at the time of assessment. The wording used is “a
wall forming a side elevation of the original dwelling house”. “Forming” is present tense, so if it no longer
exists, a wall cannot continue to form a side elevation of the original dwelling.”
conclusion should be compared with the appeal decision for
November 2009 - Code a00044, which concluded that the
determination of which elevation forms “the principal elevation of the original dwellinghouse” should be based on
the original building in its original form, rather than only considering those parts of the original
building that still currently exist. There may be a contradiction between these two conclusions].
The phrase “a wall forming a
side elevation of the original dwellinghouse” does not apply to an original side wall that has
previously been demolished.
[Relevant to: “A side elevation of the original
dwellinghouse”, A.1(h), A.2(b), E.3].
