Advice needed: I'm in the middle of a large office refurb. There are 3 lanterns (photos from outside & inside attached) which need replacing. Size of each is approx 2.5m x 2m. What's the cheapest & best way to go forward? Cost ideas?
Things to bear in mind:
1. each lantern must have an opening to provide ventilation to each office directly below (each room has no other source of natural light or fresh air).
2. What's the best way of dealing with safety issues (someone falling on to the glass)? My initial thoughts are to simply put some kind of guard railing around each lantern.
