Why it was refused

  1. In the absence of a justification of need, the use results in the loss of a family dwelling for which there is known demand and, by reason of the introduction of an over-intensive use incongruous to the established character of the area, undermines the strategic approach which otherwise prioritises meeting needs for family housing as part of the residential conversion and sustainable redevelopment of larger homes, harmfully contributes towards change in the function and character of the street and is incongruous to the established residential pattern, to the detriment of the character and amenity of the locality and contrary to Policy D3 of the London Plan (2021), Polices CDH01, HOU02 and HOU04 of the LB Barnet Local Plan (2025), the Residential Design Guidance SPD (2016) and the Sustainable Design and Construction SPD (2016).
  2. The use of the property as a House in Multiple Occupation (HMO), by reason of the intensity of occupation, would result in a harmful increase in noise, disturbance, congestion and disruption by way of increased comings-and-goings and general activity, to the detriment of the residential amenity of neighbouring occupiers, contrary to Policies D3 and D14 of the London Plan (2021), Policies CDH01, HOU04 and ECC02 of the LB Barnet Local Plan (2025), the Residential Design Guidance SPD (2016) and the Sustainable Design and Construction SPD (2016).
  3. The proposal would provide insufficient off-street parking provision and in the absence of a current parking survey in line with the Lambeth Methodology to demonstrate that there is on-street capacity for the potential overspill on the highway and surrounding roads,, the development would result in greater demand for kerbside parking and conditions detrimental to the free flow of traffic, and highway and pedestrian safety, contrary to Policies T4, T6 and T6.1 of the London Plan (2021) and Policy TRC03 of the LB Barnet Local Plan (2025).

From the council's decision notice.
