About this application

This is a planning application for a rear extension at 88 Mackenzie Crescent Burncross Sheffield S35 1US. Sheffield has handled 9,053 applications of this type. This one was decided in 53 days, 3 days quicker than Sheffield's typical decision time. There are no previous applications recorded at this address. We hold 377 applications in total for the S35 postcode area.

Why it was refused

  1. The Local Planning Authority considers that the erection of a two-storey side extension would appear as an incongruous addition that would result in harm to the character and appearance of both the host dwelling and the wider street scene. By virtue of its flat-roofed design, bulk, scale and massing, the extension would be visually prominent and out of keeping with the prevailing character and appearance of the surrounding area, which is characterised predominantly by dwellings with pitched roofs. In addition, the application fails to provide sufficient details regarding the design, finish and colour of the proposed extension. It is therefore considered that the proposed development would be contrary to paragraphs 135 and 139 of the National Planning Policy Framework (December 2024, as amended February 2025), policy CS74 of the Sheffield Core Strategy (2009), saved policies H14 and BE5 of the Sheffield Unitary Development Plan (1998) and Guidelines 1 and 2 of the Supplementary Planning Guidance on Designing House Extensions.

From the council's decision notice.
