Chambo... ...Lego and construction !!

It has either got a load of Lego technic bracing bits in there or its hanging off a metal frame.


It's pretty sturdy stuff Fluffs - for big constructions they effectively build real brick sized bricks out of lego bricks (have been to lego convention and helped build them with the kids - we did a rhino and a dragon and a heffalump).  james may built a house out of it iirc

 likely there is a "true" support for the door jam hidden behind the show piece

Most of the big things in Legoland are metal frames with brick decoration. And all glued together.
