Walking through historic Rotterdam, the Blue Building sticks out with its sky-blue cheerful roof and walls. The pleasant color isn’t the only unique thing about this building. For one thing, it is built on top of a historic brick apartment, making it look like a strange add-on. To add to the dream-like quality of the house, each bedroom of this house is actually its own separate building. Avenues and plazas appear between the separate bedrooms, giving every family member as much privacy as possible and making the house look like a tiny village. The house must truly be seen to be believed.
