Main issues, as the Inspector framed them
- Whether it has been adequately demonstrated that there is no demand for the existing office floorspace
- The effect of the proposed front boundary treatment on the character and appearance of the area
- Whether the proposed dwelling would provide acceptable living conditions for future occupiers, with particular regard to daylight and sunlight, outlook, privacy, and natural ventilation
- Whether the development would adequately promote sustainable means of travel, and mitigate its effects on the surrounding highway and transport networks
What decided it
The proposed dwelling would not provide acceptable living conditions for future occupiers due to inadequate daylight, sunlight and outlook, combined with the failure to adequately justify the loss of office floorspace and defects in the s.106 obligation securing sustainable transport measures.
The social and economic benefits of providing one additional dwelling in a well-connected location with good services were outweighed by the significant harm arising from unacceptable living conditions, unjustified loss of office floorspace, and inadequate sustainable transport provision, such that the adverse impacts would significantly and demonstrably outweigh the benefits when assessed against the Framework taken as a whole.
