We have a "light-challenged" house (bottom floor of a 20-foot wide, three story house attached at two sides). There is a light shaft that takes up significant floor space and provides minimal light to two interior room. We would like to recover the floor space but not lose all the light. Ideally, this would mean taking out the lightshaft on our floor ad putting in a "skylight". However, a standard skylight is no good because other floors have access to the shaft and as soon as we put it in they will think they can climb into the shaft and walk on it. So we would like to put in about 15sf of architectural glass block of the type that is used to make floors and decks. However, our contractor and architect have no idea where to get it or how much it costs. The only suppliers we have found are for large installations.
Any ideas about: how much the materials would cost? who might be able to supply it? what kind of installation difficulties we might face? whether we are just wasting our time?
Thanks in advance
