Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the Holland Park Conservation Area
- the depth of proposed basement and whether its construction would adversely impact on the living conditions of neighbours
- the effect of the proposal on trees of amenity value
What decided it
The detailed design of windows on the proposed third floor and side elevations would cause unacceptable harm to the character and appearance of the Holland Park Conservation Area and the group value of the historic building, with no public benefits to outweigh this less than substantial harm.
