Budapest - To build his giant Lego structures which usually take hundreds of thousands of bricks, Hungarian artist Balazs Doczy first must solve major "engineering challenges".

"Every structure has an Achilles' heel. Once it is solved, the rest of the work is easy," he said.

He needed 90 helpers for one of his most recent works - a life-sized Lego tram made up of a staggering 1.8 million pieces.

Together they put in around 6,800 hours to assemble Doczy's most ambitious project that is now on display in a bustling square in central Budapest.

The 11-metre-long Lego tram - commissioned by Budapest's transport companies and its tourist office to "public transport and creativity" - has attracted droves.
