Czech-born architect Jan Kaplicky has died at the age of 71.
Kaplicky founded the Future Systems practice in 1979, having worked with architects Norman Foster, Richard Rogers and Renzo Piano.
Future Systems designed the Lord’s Cricket Ground media centre in London, which won the 1999 Stirling Prize, and the Selfridges building in Birmingham.
Kaplicky’s blob-like design for the Prague National Library caused controversy in his native country.
Czech news agency CTK says Kaplicky died in Prague just hours after his second wife Eliska gave birth to a daughter. Kaplicky also had a son from his first marriage, to former Future Systems partner Amanda Levete.
