Why it was refused
- The proposed development, by reason of the introduction of a dual pitched wrap around rear extension, would result in an unduly dominant and incongruous addition that fails to remain subordinate to the host dwelling. The proposal would not respond positively to the established form and group characteristics of the pair, which are defined by modest mono pitched rear additions. As such, the development would disrupt the balanced composition and visual coherence of the pair, to the detriment of its character and appearance. The proposal is therefore contrary to Policies Q5, Q11 and Q22 of the Lambeth Local Plan (2021) which requires extensions to be subordinate and to respect the character and appearance of the host building and its wider context. The proposal London planning@lambeth.gov.uk SW2 9QQ would result in less than substantial harm to the character and appearance of the conservation area and no public benefits exist to outweigh that harm, contrary to paragraph 215 of the NPPF (2024).
- The proposed development, by reason of its scale and massing, would result in an unacceptable loss of outlook and an undue sense of enclosure to the occupiers of the adjoining property at No. 44 Portland Grove. In addition, insufficient evidence has been submitted to demonstrate that the proposal would not result in an unacceptable loss of daylight and sunlight to this adjoining property. The proposal is therefore contrary to Policy Q2 of the Lambeth Local Plan.
