He planned on making the room a castle but the concept was not out of the blue. They had this conversation before:
The man would say, “Well what happens when we have children, then you won’t be a princess anymore.”
The wife would always respond, “Then I will be a Queen — and Queens live in castles, you will have to build us one.”
Equipped with a concept and a new hope for their child, the man finally has a concept for the nursery room.
He started working on the skies for the ceiling but he was still researching on concepts on how he will make the wall. He came across a lightweight stone material called AirStone and it became the starting point on the creation of the castle.
