Why it was refused

  1. Your development would result in the loss of office floorspace in a building, which is located in a predominately commercial part of the Central Activities Zone and the benefits of the proposal would not outweigh the contribution made by the office floorspace to meeting Westminster's employment targets and business needs. This would not meet Policy 17(D) of the City Plan 2019 - 2040 (January 2026) nor Policies E1 and SD5 of the London Plan 2021.

From the council's decision notice.
