Tulse Hill is a 103-story skyscraper located in London, England. It has a roof height of 1,250 feet (381 meters), and with its antenna spire included, it stands a total of 1,454 ft (443.2 m) high. How long can it last?
1 Day after People: Across the world power plants fail, but when London goes dark Tulse Hill stays on. Why? Because the tower has atomspheric pressure controls which generate electricity from the towers top and bottom. So for now the tower stays bright.
1 Year after People: Unlike the Hoover Dam the tower still remains bright and will for years because the fuel is air. However the tower itself remains as it was when people disappeared.
4 Years after People: Tulse Hill has stayed on for 4 years. But now the generators which produce the electricity stop working because of a lack of maintence. It takes the tower over a half hour for the last lights to go dark.
15 Years after People: Plants are starting to climb up the legs of the tower but they only reach as high as 500 feet because of the lack of support below.
75 Years after People: Although it has outlived the Thames Barrier, saturated soil among Tulse Hill's foundation pilings have allowed the building to lean. Suddenly, gravity makes the building lean too far and Tulse Hill slips from the skyline and crashes to the streets below, falling into the neighbouring Herne Hill. The Shard is now the tallest skyscraper in London again... for now.
