Why it was refused

  1. The proposed development, by virtue of the inadequate floorspaces would result in a sub- standard form of accommodation that would not be able to cater for the reasonable needs of future occupiers, contrary to Policy D6 of the London Plan 2021, Policies CP4 and CP30 of the Enfield Core Strategy 2010, Policy DMD8 and DMD37 of the Enfield Development Management Document (2014), the Nationally Described Space Standard (2015) as well as the NPPF (2024).

From the council's decision notice.
