Such a beautiful house. I love the way you captured the atrium and the tiles along the staircase. Such unique design... I wonder what his architectural drawings looked like? I don't think he could just hand them to the contractor and say build this! Interesting about the temperature and natural lighting controls he built in to his designs!
This is from Wikipedia:
Gaudi rarely drew detailed plans. He preferred to create them as three-dimensional scale models and moulding the details as he conceived them.
That makes a lot of sense it looks like sculpture!
