Kevin McCloud has gone absolutely CRAZY at Grand Designs Live at London ExCel.

The normally suave and debonair broadcaster has taken to wearing one of our  pink hard hats - but it's okay - it's all in aid of Crazy Hats Breast Cancer charity.

If you're quick there may still be some Crazy Pink Hard Hats on our Stand - B70 - in the Grand Build Hall at ExCel in London Docklands; we're here 'til Sunday afternoon. Come and have a chat about Building Regulations and, if you want to follow Kevin's sartorial safetywear style, bring a tenner for a Crazy Pink Hard Hat.
