Generally speaking, that's the name of the building in Billund were LEGO designers create the sets that end up in LEGO's line of products. Usually, LEGO doesn't permit pictures to be taken in this building, but since it was recently completely remodeled, the design team that did the work was allowed by LEGO to take some pictures to showcase their work.

Personally, I would love to take a ride on that slide!
Thanks to my buddy Pierre Normandin, LEGO CITY designer, for the link and the heads-up.
