Planning appeal decision
Hazeldene, Ascot Road, Holyport, Maidenhead, SL6 2HY
Planning appeal 3317564 at Hazeldene, Ascot Road, Holyport, Maidenhead, SL6 2HY (Royal Borough of Windsor and Maidenhead) was allowed in part (a split decision) on 13 December 2023 by Inspector Guest H, by written representations.

Main issues, as the Inspector framed them
- whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
- the effect of the proposal on the openness of the Green Belt
- the effect of the proposal on the character and appearance of the area and whether it would preserve or enhance the Holyport Conservation Area
- on the basis that the proposal would be inappropriate development in the Green Belt, whether any harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations so as to amount to very special circumstances required to justify the development
What decided it
The first floor extension would result in a disproportionate addition to the original building and would harm both the openness of the Green Belt and the character and appearance of the Holyport Conservation Area, with insufficient public benefits to outweigh this harm and justify very special circumstances.
