Summary of Case (appeal
The property is a two-storey
semi-detached house with a hipped main roof. The application was for a proposed hip-to-gable roof extension, a
large rear dormer, and two front rooflights.
The key issue was whether the
proposed enlargement of the roof would be contrary to Class B, part B.1(c), which states that “Development is
not permitted by Class B if … the cubic content of the resulting roof space would exceed the cubic content of
the original roof space by more than— (i) 40 cubic metres in the case of a terrace house, or (ii) 50 cubic
metres in any other case”.
The appellant calculated the
increase in volume to be 49.65m3, the Council calculated it to be 54.07m3, and the Inspector calculated it to be
52.18m3. The Inspector therefore dismissed the appeal.
No conclusions (because the
dispute revolved around a maths calculation, rather than an interpretation).
