Why it was refused

  1. The proposed Unit 2 would fail to provide a minimum floor-to-ceiling height of 2.5 metres across at least 75% of its Gross Internal Area. In particular, the submitted section drawings indicate that the loft floor would have a floor-to- ceiling height of approximately 2.4 metres and would comprise approximately 47.1% of the total Gross Internal Area of Unit 2. As a result, Unit 2 would provide substandard internal accommodation and an unacceptable quality of living environment for future occupiers. The proposal is therefore contrary to Policy D6(F), Part 8 of the London Plan (2021), Policy 3.5 of the Ealing Development Management DPD (2013), and the London Plan Guidance: Housing Design Standards LPG (2023).

From the council's decision notice.
