Soojin Hyun designed this strange concept called the House on the Table. What looks to me like a tree house on a desk is a structure conceived as a sort of personal fortress intended to safeguard a person's privacy. The House on the Table comes complete with a bookshelf, a vaulted ceiling, four walls, look-out portals and interior lighting.
From the images, the structure looks bigger than a cubicle from the inside, and it actually seems quite spacious. I think it takes up way too much space though and it is just a crazy idea.
