British-based Czech architect Jan Kaplicky, has died at the age of 71 after collapsing in Prague, it was announced today.

The designer of the award-winning media center at Lord’s cricket ground in London, died just hours after his wife Eliska gave birth to their daughter Johanka, according to the Czech media.

Kaplicky collapsed on a Prague street on Wednesday evening according to Prague’s rescue services, speaking to news agency Associated Press.

His consultancy Future Systems also designed the futuristic Selfridges building in Birmingham, the Stonehenge tourist center and a floating bridge linking West India Quay and Canary Wharf in London.

The consultancy also won a design contract 2007 to build the new building of the Czech National Library in Prague, which would have been Kaplicky’s first building in his homeland.
