The tree of creativity is in the centre of the main staircase of the building, towering up to the masterpiece gallery on the top floor. Among its branches are models depicting different product lines from LEGO's history, and it's topped with a crane that symbolises that the company's history is still under construction. The doors on the end of the barn slide open and a pair of handles inside, like those on the exterior, prevent them from being removed completely.

The completed model comprises a section of Santa's workshop with walls on two sides. Sliding doors on one of them allow ingress of raw materials and what I presume is a conveyer belt behind a wooden door on the other is provided for the dispatch of finished presents. Several renditions of the LEGO house have been produced over the years, from the definitive 21037 LEGO House to the tiny 854015 LEGO House Magnet. This one sits somewhere in between in terms of size. It's just about big enough to be able to model the distinctively designed building reasonably accurately. Three dinosaurs, one made from Duplo, one from System pieces and one from Technic, take centre stage in the masterpiece gallery.

Dinosaurs

It's the weakest of the five models, simply because it's too small to be able to do the subject justice, although the mini yellow castle made from about 8 pieces is cute, as is the fire engine with just 6. Nevertheless, if you have the first one you'll probably want this one too. I just hope there's something you still need to buy at LEGO.com next month! A solitary elf armed with a paintbrush toils away at a workbench while Santa oversees the operation with the help of a computer on a shelf by the window. It's a delightful scene!

This highly-detailed minifig-scale model of an ENGEL injection moulding machine is also excellent and, if it were available more readily, could be used in bulk to populate a model of a LEGO factory. It's certainly a hefty GWP: the box, which is styled like those of the larger models, is deeper and heavier than those of most free gifts.The set was provided for review by LEGO. All opinions expressed are those of the author. Box and contents The instructions for both this and 40564 Winter Elves Scene suggest that they are designed to be butted up next to each other but to be honest it looks a bit odd. The only thing they have in common is the width of their bases.
