Konijnstein
Bol.com wanted to surprise one of its customers with an upgrade of their order, which had come too late. After finding out that Ann-Sophie and her bunny Kazzimir were huge Harry Potter fans, the idea of Konijnstein was born, a Hogwarts (Zweinstein in Dutch) castle/bunny cage for both Ann-Sophie and her pet to enjoy.
The added challenges were many, from designing a Hogwarts-like castle that shouldn't exceed specific measurements, a tight timeframe and of course building a model that is pet-friendly and can also be used as a cage.
