Tom Dyckhoff explores the contribution of Lego to architecture, and its continuing influence, arguing that it's changed the way we think about buildings.

Lego's plastic yellow bricks were launched in the 50s, and resonated with new visions of rebuilding society - with ethical, imaginative children's play at its heart. Tom meets the artists and architects reared on Lego who are using it to reimagine our cities today, from Bjarke Ingels, the leading architect of his generation, to international artist Olafur Elliasson, whose Collectivity project took three tonnes of Lego to the citizens of Tirana, Albania.

But with Hollywood franchises and huge expansion, has Lego lost its original ethos of creativity and construction? Tom looks at Lego's successors and how cult computer game Minecraft may be set to transform the cities of the future.
