Almost anything made out of LEGO is pretty cool. These are pretty good works of art themselves. The scene made, the lighting effects of the photos, all of it is really cool.
It’s hard to tell from the photos, but these are massive structures. Probably big enough for small pets to live in at 5′ by 6′ by 3′. The bottom house uses between 110 and 130, thousand individual LEGO bricks. And, before you ask, yes it’s only black, grey, and white bricks.
