Ah-HA! This is what we can do outside the back door that currently has a cement landing and staircase built directly over a basement window (the stupidest design decision EVER!). Perforated metal would be the perfect replacement to let light into the rec room.
Heliobus mirror shaft brings daylight into the basement & turns your dark basement into living or working spaces. The principle is as simple as it is ingenious. A sides mirrored module directs natural day-& sunlight into the basement. The outside is covered with a walk-in bulletproof glass... the ventilation frame surrounding the bulletproof glass, ensures there is enough ventilation in the basement room. You can even receive eye contact with the outside world, sky, clouds & plants.
