It’s not 100 per cent Lego, but it’s close. There’s a timber “safety frame” inside the walls to provide an extra level of stability, which is probably for the best, and there are non-Lego lights and stuff, obviously. But it’s still a whole lot of Lego. They have three million bricks on hand and may need more.
Oh, and about that toilet? Here’s what the designer has to say about it:
Oobject: The toilet – right, this the thing we want to know most, how does a Lego toilet work – I mean how much of it is actually Lego?
BG: Pretty much all of it. The exact design is being specified by the interior designer and will have a Lego cistern connected to a Lego bowl via a Lego pipe. It will even have a Lego flusher.
