Appeal Decision 202 - Certificate of Lawful Development.

January 2011 - Code a00202

Summary of Case (appeal dismissed): 

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. 

Main Conclusions: 

·       No conclusions (because the dispute revolved around a maths calculation, rather than an interpretation).
