A life-size replica of a 1973 Viscount Royal caravan, built with nearly 300,000 Lego bricks in Queensland, has broken a Guinness World Records title for the world's largest Lego caravan.

Caravanning Queensland and caravan park group Top Parks beat the previous title holder by 73,472 bricks.

The Lego caravan featuring a double bed, wardrobe and cupboards with sliding drawers, was built by a team of up to 20 people from Queensland and interstate, using 288,630 bricks.

It took about five months and more than 530 work hours to build, using 70 litres of glue to piece the pieces together.
