It's not really a pre-fab hut ...
Pity there is just one teeny ingredient missing. Just where are all the children going to go? Portakabins, of course.
But this is not a Portakabin as you know it. It seems that the familiar grey cube has undergone a transformation worthy of New Labour.
The company's latest unveiling, the Lilliput nursery, is apparently more a "brightly coloured collection of little boxes". It has been designed by trendy London architects Cottrell and Vermeulen, with furnishings by Rosalind Farley, a hip interior designer usually found in the pages of Elle magazine.
For less than the price of half a playground wall you get an outside play area, wet area, veranda and fittings - including toddler-sized showers and heated benches.
"We are the most trusted name in modular building systems you know," enthuses Robert Minton-Taylor, Portakabin's own spin doctor. "And I think you'll find those damp boxes littering playgrounds in the 1970s and 80s weren't actually real Portakabins, but poor imitations. Some of our units have lasted longer than a lot of 70s tower blocks."
Bozena Laraway, head of St Albans Catholic primary school, recently took delivery of her spanking new Lilliput. She says: "My immediate reaction was urrggh - grotty. But I went to see the factory and now I'm converted. I think mine is the most beautiful building in St Albans."
