That is awsome ideas for multi-level apartment. A four-story penthouse, called Skyhouse, inside one of the oldest skyscrapers in Lower Manhattan, designed by by architect David Hotson, adds a new twist to an otherwise austere living room: an 80-foot slide.
But before sliding you have to get to the top – just brave the four-story climbing column that starts in the living room. On the fourth floor you’ll to enjoy the impressive panoramic views of the city. If you want to come down use 80-foot indoor slide that snakes throughout the interior of the home.
