The Chocolate Factory.
Being a chocolatier, Willy Wonka's chocolate factory holds great importance to him as this is affectively his home, career and all other aspects of his life. He is so used to these surroundings hardly venturing outside and experiencing the world behind his factory. Nobody is allowed to enter his factory (apart from the occasion concerning the 5 golden tickets), therefore meaning the closest Willy Wonka gets to everyday human interaction is with his oompa loompa workforce.
Taking these factors into consideration, I decided to make my life box show resemblances of the chocolate factory yet not be a complete replica due to the fact that this life box is also a getaway place for Willy Wonka. Therefore, by only resembling the chocolate factory will allow Willy Wonka to feel at home within his factory, without having to worry about the duties that lie there.
