Inspector: Goldberg V

Main issues, as the Inspector framed them

the effect of the porch, roof enlargement and first floor rear extensions on the character and appearance of the dwellings and area
the effect of the first floor rear extensions on the living conditions of the occupiers of 23 and 29 Lothian Avenue in respect of daylight and sunlight

What decided it

The development fails to respect the scale, form and proportions of the host properties and the established character of Lothian Avenue, appearing as dominant and incongruous additions contrary to the development plan, while the enforcement notice's requirements were excessive and the compliance period unreasonable.
