I just noticed this in an ad in RM for a new Peco kit. It's designed as a 'cricket pavilion', but the eagle eyed will spot a bit of nifty re-packaging of the doors and windows from their station kit and the roof from the Will taximan's hut. The walls are milled wood the rest is plastic.
At seven quid and a little work I'm thinking light railway station building. Though the roof would probably be the first bit to go.
