Talk about being one with nature! Check out this Cool House Factor: Glass Treehouse. This plan was designed by Kazakh architect Aibek Almassov of A. Mascow Achitects. This rending of a tubular glass house in the Kazakhstan woods encases a full-grown tree. There are four floors of living space, all accessible through a spiral staircase. This glass treehouse was commissioned by a businessman who wanted a home for a two people and a place that would allow for his spiritual and creative development. Here are some renderings of this unique home! Want to rent this place out? Don’t get too excited — it actually hasn’t been built yet! But it has secured funding and should be this year!
