There are some people who have so much energy they can practically climb the walls. The SkyHouse, designed by David Hotson must be meant for those folks.  The amazing four story abode features a 50-foot climbing wall and an 80-foot stainless steel slide that winds its way around the columns. The vertical lines in the SkyHouse are beautifully accented by the organic, spiraling slide, and its vaulted ceilings carve out rooms and platforms for viewing the city outside.
