Los Angeles, Aug 8 - When the going gets tough for Hollywood star Brad Pitt, he turns to his first love -- architecture.

The actor admits that whenever the paparazzi gets too much to handle, he plans on making buildings, reports contactmusic.com.

'Architecture is like play to me. As a boy, you play with Tinker Toys and Legos and you get interested in how things are made, like cars and drills and all that. Years later you come back to what interested you as a boy. Now, if I have something that I'm dealing with that's causing me a lot of stress, my mind goes to architecture,' said Pitt.

'I walk around the yard and start thinking about what I need to do to the house structurally. It's similar to puzzles in that way, like a crossword puzzle or anything else I can put my mind into. It's a relief for me.'
