Indeed I got this layout concept since 2017, back in the summer of French country side. I don't remember exactly how it pop out in my mind but it's stuck there since! I think some onepage projects have influenced me such as XXX, XXX and XXX. I really love their concept of making who goes out of the trends, taking the risk of messing up everything.
I wanted to create something really simple and fast to use: I wanted the user to arrive directly with a view of my desk when he visits my domain name.
