Real-life scale is not a joke! The amazing architects have a great vision in their minds and they realized their ideas in the most fun way. They use 1:1 scale for their plans. Obviously, they need more space to draw them, but the final result has quite a big effect and impact. Maybe these plans are not as practical as the regular ones, but they surely are more fun and it is easier to visualize.
