im not familiar with cal wood but for flooring glitsa is a great product

5th floor...maybe a hobby room. E.g. stargazing with telescope. Ideal if the 5th floor in building contained a patio...no roof...the patio is the roof for the lower stories.

Rules can be tricky, because it really depends on the chandelier, for example, does it have a small metal part in the middle or any crystal pieces which hang lower than the majority of the chandelier? We like to be able to see underneath the main part of the light fixture, when standing beside the table - if for example you were using the dining table to serve buffet style... or for a wine tasting. It's best not to cut too much of the electric wire or chain until you're sure you like the length. I hope that helps?
