Why it was refused

  1. The size of the proposed outbuilding would be out of scale with the existing house and would dominate its appearance/the street scene. As such it would be contrary to Policy PG3 of the Birmingham Development Plan 2017, Birmingham Design Guide SPD 2022, Policy DM2 of the Development Management in Birmingham DPD 2021 and the National Planning Policy Framework.
  2. The proposed extension does not comply with the 45 Degree Code for House Extensions and would lead to a loss of outlook and light to No.23 Westhay Road. As such the proposal would be contrary to Policy PG3 of the Birmingham Development Plan 2017, Birmingham Design Guide SPD 2022, Policies DM2 and DM10 of the Development Management in Birmingham DPD 2021 and the National Planning Policy Framework.
  3. Inadequate private amenity space is proposed and as such the proposal would be contrary to Policies PG3 and TP27 of the Birmingham Development Plan 2017, Birmingham Design Guide SPD 2022, Policy DM2 of the Development Management in Birmingham DPD 2021 and the National Planning Policy Framework.
  4. The proposed building would constitute as an over-intensive use in comparison to the original footprint of the main property. As such, the proposal would be contrary to Policy PG3 of the Birmingham Development Plan 2017, Birmingham Design Guide SPD 2022, Policy DM2 of the Development Management in Birmingham DPD 2021 and the National Planning Policy Framework.
