The world's largest Lego store has just opened in London. The new landmark Leicester Square store covers an area of 914 square metres over two floors. A model of Big Ben is currently being built using more than 200,000 bricks. When it is completed, it stand nearly seven metres high, dominating both levels of the store. The Lego version of the Elizabeth Tower will feature Big Ben's chimes and a working clock face which will be illuminated at night – just like the real thing.

Among the Lego models in the store is a London Underground carriage which took 4,000 hours to make. IBTimes UK takes a look inside the new Lego store.
