Why it was refused

  1. The proposed change of use of the property to a 5-bedroom HMO would result in the loss of a single family dwellinghouse for which there is a known demand, and which is considered a priority housing type within the Borough. The applicant has not demonstrated that there is an identified need for the accommodation proposed at this location. Furthermore, its use as an HMO in a street with poor PTAL 2 and characterised by predominantly single family dwellings would contribute towards change in the function and character of the street and be incongruous to the established pattern of residential development, detrimental to the established character of the area. The proposal is contrary to NPPF (2025), Policy H9 of London Plan (2021), Policies CDH01, HOU02 and HOU04 of the Barnet Local Plan (2025) and the approved Sustainable Design and Development Guidance SPD (2026).
  2. The proposed change of use from single family dwellinghouse into 5 bed HMO for 6 person would harmfully increase noise generating activities at the site such as residents entering and exiting the site, using the garden and parking on the surrounding road network, to the detriment of the residential amenities of the occupiers of the adjoining neighbouring properties. The proposal is contrary to NPPF (2025), Policy D13 of London Plan (2021), Policies CDH01, CDHO2 and HOU04 of the Barnet Local Plan (2025) and the approved Sustainable Design and Development Guidance SPD (2026).
  3. The development does not include a formal undertaking to enable an amendment to the Traffic Regulation Order and contribution towards the associated monitoring costs to mitigate the on-street parking impact in the vicinity of the site, leading to increased kerbside parking and conditions detrimental to the free flow of traffic and highway and pedestrian safety, contrary to Policies TRC01 and TRC03 of the Local Plan (2025).

From the council's decision notice.
