Why Leeds refuses single-storey side extensions
The council's own words, quoted from recent decision notices.
9 Woodlea Garth Meanwood Leeds LS6 4SG
“If you wish to pursue this matter, you should submit a full planning application: 1) The Local Planning Authority considers that the proposed amendments to the scheme would result in the introduction of white render to a highly prominent elevation of the application property and the installation of a heat pump, which would introduce a noise source that could adversely affect the amenity and living conditions of neighbouring occupiers. Taken together, and when considered in the context of the originally approved scheme, it is considered that the proposed amendments would require a full assessm…”
Crofton Villa Crofton Terrace Shadwell Leeds LS17 8LD
“1) The Local Planning Authority considers that the proposed extension, by reason of its excessive scale, massing and design, would fail to appear as a subordinate addition to the original dwelling and would erode its simple and prominent architectural character. The proposal would result in unjustified harm to the significance of the Shadwell Conservation Area through the diminished contribution made by the host dwelling, a positive building within the conservation area, and through the erosion of its architectural integrity and legibility. This harm is not considered to be clearly nor convin…”
1 Whinbrook Grove Moortown Leeds LS17 6AF
“1) The Local Planning Authority considers that the proposed development, by reason of its prominence, scale, siting and design, would fail to respect the character, scale and appearance of the host dwelling and would erode the openness of this prominent corner plot within the Whinbrook Grove cul-de-sac. As a consequence, the development would result in a cramped, overly dominant and incongruous form of development that would fail to respond positively to its context, causing harm to the character and appearance of the application site and the wider street scene. The proposal is therefore cont…”

How these figures are made
Planning applications Leeds City Council received Oct 2021 to Oct 2026, from the council's public planning register as collected by Planning Signal. An application counts as a single-storey side extension when its own description says so (rules-based classification, tested against blind labelled samples). Duplicate records of one application are counted once. The approval figure counts approved and refused planning applications only: withdrawn and undecided ones, lawful development certificates and prior approvals are left out. Decision times use the received (or validated) date and the decision date the council published.
Past decisions describe what happened to other applications. They are not a prediction for yours: every application is decided on its own design and the council's current policies.
