OHHH....I love that trush.! Can't just imagine floating in that.! Luke...that is amazing, but I would be to scared that I would fall over the edge.

Art studio/ music room/library....anything creative...sewing, reading...writing...It is a beautiful serene space where one could spend many a quiet and memorable time. I can just see my cat making a beeline for what he would perceive is open space only to find himself concertinered up against the glass! If I owned this room I would have to have a frosted border about 30cm high all along the bottom of the glass, Whover owns this place is pretty fortunate and I hope they count their blessings.

Re karen3812's comment about the direction of the flooring, it would be good to know what was behind the decision to do it as they did
