A five-storey building in Shanghai has apparently “walked” from a nearby factory to the new location.
The developers say the grey Shanghai Tower was built without foundations, leaving it vulnerable to the current sea level rise.
Sea levels are rising faster than estimated and some scientists say buildings may find it increasingly difficult to withstand them.
The developer has promised to refurbish the building in time for Shanghai Expo 2020.
Some builders are using pneumatic drills to demolish their walls and bring them up on hydraulics – a method first used by miners in the 19th century.
Sometimes it looks as if the walls are taking steps. On certain floors it appears as if the building’s terra cotta walls have risen with the tide.
The Shanghai Tower, which opened in June this year, stands at 248 metres (832ft) tall, and was constructed from 88 prefabricated modules.
The skyscraper tower is believed to have shown, in theory, the first visible sign of the phenomenon in the East China Sea.
