Skyboat is a two-storey building set above a 613 metre deep sinkhole in Leye, China. Hotel rooms are placed on the ground floor, a cafe on the first floor and a viewing platform on the roof. The platform includes a walk-on glass floor measuring 10 by 12.5 metres. The building spans the narrow passageway at the top of the sinkhole and cantilevers 34 metres and 22 metres to each side of the mountain ridge. A low centre of gravity allows the structure to balance itself. Only five supports are used, which limits damage to the local plants.
