Why it was refused
- The proposal to convert the property to short stay accommodation, by reason of the intensification of use, would harmfully increase noise, disturbance, vehicle movements and disruption through associated general activity, especially during the frequent changeover periods, in a relatively quiet street characterised by single household dwellings, resulting in an adverse effect on the residential amenity of neighbouring occupiers and incongruous to the established character, contrary to Policy HOU05 of the LB Barnet Local Plan (2025), the Residential Design Guidance SPD (2016) and the Sustainable Design and Construction SPD (2016)
- The proposed flat, by reason of sub-standard floor area, inadequate ceiling height and poor outlook, would fail to provide satisfactory living conditions for future occupiers, contrary to Policy D6 of the London Plan (2021), Policy CDH01 of the LB Barnet Local Plan (2025), the Residential Design Guidance SPD (2016) and Sustainable Design and Construction SPD (2016)
From the council's decision notice.
