Prince William and Prince Harry can be seen in action on the set of DIY SOS in a trailer for the upcoming show. The Princes joined forces to turn derelict houses in Manchester into homes for ex-service personnel as part of The Big Build: Veteran's Special project, due to air on BBC One on Wednesday.

The trailer for the special show sees the brothers helping to lay paving stones while a crowd of workers gathers around to watch, until host Nick Knowles tells them: "Get back to work, I'm sure you've seen a prince lay a paving stone before."
Princes William and Harry joined the DIY SOS team in September
William can also be seen talking about the importance of supporting ex-servicemen and women, explaining to Nick: "Having that brotherhood means an awful lot to the guys."
The royal brothers joined the DIY SOS team in September for the final stages of the project, which has renovated eight buildings, rejuvenated the façade of 62 houses and built a training and counselling centre on site.
It was recently revealed that the royals acquired an unusual nickname during their visit to the set after one member of the team broke protocol by declining to address them as "Your Royal Highnesses" or their preferred monikers, "Wills and Harry".
"I'd been told I should address them as Your Royal Highnesses, which I did as I welcomed them," Nick told HELLO! "Then I said: 'How should we do it from here?' and they told me: 'Just Wills and Harry will do.'"
He continued: "They joined in all the banter, giving as good as they got. Billy, our electrician, calls everyone on site 'Sausage', so he tried: 'Your Royal Sausage.' Harry said to him: 'Listen, if you're going to call me Sausage, it's going to be a very long day!"
DIY SOS: Homes for Veterans airs on BBC One at 8pm on Wednesday.
