Why it was refused

Insufficient information has been provided to ensure that the amenities of the future occupiers are not prejudiced by rail and/or road traffic and/or mixed-use noise in the immediate surroundings, in particular adequate continuous noise monitoring outside of the building, effective monitoring duration, detail on assumptions and sources for noise modelling and verification, information on noise climate, information on whether source of data transformer running at max and source of data detail information, statistical analysis on night time noise, detail on the surrounding commercial sites, reference to overheating in the rooms facing the railway/ M1, information on transformer's noise penalties and detailed explanations on the derivation of sound levels. In the absence of this information the proposal would be contrary to Policy ECC02 of the Barnet Local Plan (adopted March 2025), the Sustainable Design and Construction SPD (adopted April 2016) and Policy D13 and D14 of the London Plan 2021.

From the council's decision notice.
