The humble letterbox...
How should it be designed?
Box design
- floor area sufficient to lay a C4 envelope (or MacBook Air, which is the same size to within 2mm) flat
- 'mouth' sufficient width to eat said C4 envelope. Approx 3cm high.
- entire box should be approx 10cm high to prevent regurgitation theft
- top and sides of mouth should have overhang (lips!) to protect from weather.
Security
- Box should be lockable, and internal mail not be reachable through the mouth or other openings.
- Box should be securely bolted down to prevent theft of entire box
Placement
- Between approx 100 and 150cm from ground level (keyed from height of mouth), and no further than 50cm back from the path (ie, postie reach)
