| Example Number | Source | Property Date | Storeys/Location | Property Type | Summary Information | Hazard | Link |
| 1 | IDea | 1947 | Basemenrt bedsit | 3 storey (plus basement) semi detached house | With
just one small unopenable window, there is minimum natural lighting and
artificial lighting is required for basic domestic activities. | B | Example 1 |
| 2 | BCC | ? | rear room in basement multi occupied flat | converted house | The
front of the flat is at ground level, but the sloping site means that
the rear is below ground level. The rear bedroom has very limited
natural light and no view; artificial lighting is required at all times
of the day and night. Additionally, there is no direct natural light to
the shared lounge. | C+ | Example 2 |
| 3 | BCC | Listed Georgian property pre 1920 | Basement/sub basement maisonette | 6 storey building | The
maisonette occupies the lower two stories of a listed Georgian
property, which has been converted into 5 separate flats. Two rooms in
particular, have poor outlook and little natural lighting, and it would
be difficult to carry out normal domestic activities without artificial
lighting. However, this is ameliorated by reasonable levels of natural
lighting in most other rooms, and outlooks over the recreational space. | G | Example 3 |
| 4 | BCC | Georgian | Basement flat | 4 storey with commercial use to ground floor | The
flat has no windows direct to the outside, the only natural light being
via two opaque glass block light-wells into the living room and bedroom
only. Artificial lighting is required for virtually all normal
activities. The outlook from the accommodation is non-existent. | B | Example 4 |
| 5 | CLG | 1960s | Detached house | 3 bed roomed | The
height of the Leylandii hedge, which is within the boundary of the
property, blocks any direct sunlight into the ground and first floor
rear rooms, and makes the ground floor kitchen and dining area
particularly dark. | F | Example 5 |
| 6 | CLG | Geogian | 2 bed basement flat | 4 storey georgian villa converted into self contained flats | Flat lies almost totally underground, with only the first bedroom having a normal window to the outside. Apart from the
difficulty of reading without artificial light, it is likely that most
people would also suffer some psychological harm from living in the
dwelling for a year or more. | A | Example 6 |
