Treehouse - I'm from Barcelona

I have built a treehouse 
I have built a treehouse 
Nobody can see us 
it's a you and me house 

I've been climbing rocks and stones 
been collecting broken bones 
I've been swimming across the lakes 
just to find this perfect place 
I got lost into the woods 
I've been covered up in mud 
I've been going through a lot 
just to find this perfect spot
