Outside the apartment door in Uppsala stands a lego guy. And inside the two-bedroom, the entire living room is full of lego. So it has been all autumn.

- I might pick it down after Christmas, says Per Johansson, who has been building Lego since he was four years old.

This is the third time Per Johansson has built a lego world in his living room.

- I'm not building for it to be nice, but for children to be able to play with it, says Per Johansson.

Here come relatives, friends and friends, but also people he has never met before. Rumors of his lego world have spread in social media.

In the clip above you get an answer as to why he does this.
