Justification

There does not appear to be any feasible solution. While it might be possible to change the opaque glass blocks in

the light-wells to clear (transparent) glass, as the light-wells are part of the public pavement there would be a loss of

privacy. Such work would make little difference, and may not be permissable or even possible.

Justification:

The whole flat lacks adequate natural lighting and no rooms have any outlook. As natural lighting

levels are extremely low, artificial lighting is required for virtually all normal activities. However, there is

some illumination provided by the borrowed lights. But, the outlook from the accommodation is non

existent resulting in an extremely oppressive atmosphere which is likely to result in psychological harm

The lack of any alternative well-lit rooms means that exposure to the hazard is almost inevitable.
