Fichte-Bunker

The gasometer itself is protected,[1] but in September 2006 the State of Berlin's Real Property Fund sold it to private investors and residences have now been constructed on the roof.

Both were topped with the "Schwedler cupola", an engineering innovation of his that used an unsupported curved steel vault to span diameters of up to 45 metres (148 ft).

[5] The Kreuzberg gasometer was one of four built to supply gas for street lighting during Berlin's explosive growth in the 1870s.

At the end of 1940, Fritz Todt, Inspector-General of Buildings for the capital, had it converted into a 6-level air-raid shelter, one of three intended primarily for the protection of women and children.

[citation needed] In September 2006, the State of Berlin's Real Property Fund sold the building and approximately 8,000m2 of land to the newly formed development company SpeicherWerk Wohnbau GmbH.

[2][19][20] Despite objections from neighbours to the density of the development, planning permission was granted and work began in December 2007; the freestanding residences were completed in 2009.
