In love with this rainbow spiral staircase. Why don't they make such things mandatory in every house?
The staircase is centralised in The Rainbow House.
The house is a living artwork in which every corner offers a unique and magical discovery. In the master bedroom, a circular bed rotates into position so that you can look out any window. A trap door in the floor pops open to reveal a slide that zips you down to the living room below, where an over-sized sofa creates a 12 x 8 metre soft piazza for playing, sleeping and living.
