Duncan Titmarsh - the country’s only official “Lego Certified Professional” - and his team are hard at work building an extraordinary Advent calendar, measuring 16 foot by 10 foot, with 24 opening doors, each opening onto a Christmas scene – a turkey, surrounded by sprouts; an elf, complete with mug of steaming coffee, and a couple kissing under the mistletoe.

The structure is made from 550,000 bricks in total, all aided by little drops of glue.
