Cube House Museum (Kijk-Kubus), Rotterdam

Step inside one of the strangest, most photographed houses in the Netherlands

Rotterdam is famous for bold architecture, and nothing captures it better than the Cube Houses: a cluster of bright yellow homes tilted at 45 degrees, each balanced on a pillar like a tree in a forest. 

Designed by Piet Blom and built in the 1980s, they were his answer to a simple question, how do you fit homes over a busy road without cutting the city in two? The Kijk-Kubus, or "show cube," is one house opened up as a museum, so students can go inside and see how anyone actually lives at that angle.

For a group, it is a short, memorable stop with real talking points. Beyond the novelty, it opens up a genuine discussion about how cities use limited space, building upward and over roads rather than sprawling outward.

It sits right in the centre of Rotterdam, beside the Markthal and Blaak station, so it slots easily into a wider city day.
