See houses based on trees in Rotterdam

Rotterdam was all but destroyed in World War Two and as such has been rebuilt with some of the most interesting modern architecture on the continent.

One of the more unusual sights in Rotterdam is the Cubic houses. Built by Piet Blom in 1984, the cube-shaped houses are intended to look like abstract representations of a tree.

What makes these houses different, though, is that they are shaped as cubes and yet are tilted and mounted on hexagon-shaped pole structures above a bridge.

The living area is triangular and because of the houses' shape, its windows look down onto the street below.

The middle level of the houses contains a bedroom and bathroom and the top floor, again triangular, is a pyramid made of glass.

All of the houses are lived in, but one is open for the public to view, according to essentialtravel.co.uk.
