Retention Permission for alterations to permitted application ref: SD22B/0256 alterations include, reduction in area of extension to side of existing dwelling minor alterations to internal layout and increase in height from permitted 3m to 3.3m

Refused

Core Refusal Reason

The Inspector recommends granting permission for retention, concluding that the 300mm increase in height above the previously permitted 3 metres and the reduction in overall floor area (from 34 sq. m. to 29 sq. m.) do not result in significant negative impacts on the residential amenities of adjoining properties by way of overbearing or overshadowing.

Decision Maker's Conclusion

  • The 300mm height increase in the extension as constructed is considered minor and does not result in significant overbearing or overshadowing impacts on the adjoining residential properties.
  • The contemporary design and external finishes of the extension are compatible with the existing dwelling and do not negatively impact the visual amenity of the surrounding area.
  • The development does not result in a loss of privacy for neighbors, as no side-facing windows were included and the rear-facing windows are appropriately oriented toward the subject site's garden.
