Many Happy Returns to Princess Charlotte who celebrates her first birthday on May 2. So far, there have been no official photographs of the royal nursery or playroom, though we do know doting grandfather Prince Charles has installed a shepherd's hut at Highgrove for the Princess and her brother, Prince George.

Most children manage quite well without a shepherd's hut, of course, but psychologists agree that having their own space can boost kids' self esteem and help them develop their own indentity.They need toys, too, though probably not 800 – the number Prince George is said to have received last year, including a toy polo mallet, a surfboard and an amphibious boat.

These six properties all have ready-made playrooms or children's bedrooms. Simply add your own princess – or prince.
