Prince William and Prince Harry showcased their do-it-yourself (DIY) skills on Wednesday morning during a special house construction project for Armed Forces veterans.

The Duke of Cambridge and his brother wore personalized hats as they joined other volunteers, along with former servicemen and women to help put final touches to the project, People reported. The housing project, located in Manchester, is part of BBC’s makeover show, “DIY SOS," which aims to renovate eight buildings and do restoration work on 62 houses. The homes will ultimately go to Armed Forces servicemen and women, veterans as well as longstanding residents. 

During the royal brothers’ visit to the Manchester site, Prince William helped paint the walls of some of the homes, while Prince Harry helped lay down slabs of paving stones. There was also a little friendly competition between the two brothers when Prince William reportedly told Prince Harry that it was “game on” after being briefed about the work that they needed to do.

Mark Millar, project manager, told reporters at the site that the bearded Prince Harry was a “really great lad” and even described him as a “legend.” Millar was also impressed with the young prince’s skills and remarked that Prince Harry “can come and work on a site of mine anytime he likes."

Meanwhile, other "DIY SOS" volunteers were also starstruck with Prince William and Prince Harry’s visit. BBC reported that serviceman Paul Murphy said he doesn’t have plans to wash his hands after shaking hands with Prince William twice that day. Meanwhile, resident and volunteer John Wilkinson found the royal visit “brilliant” and joked that he may soon become single again after his wife met and chatted with Prince Harry. 

Wilkinson told BBC, "They were gentlemen. They were flirting with Margaret more than anyone else. She was well chuffed with Harry. I think she is going to leave me."

The DIY SOS project has been described as “ambitious” and will not only add homes for veterans; a support center will also be built on site to help re-train and support those who suffered mental and physical injuries.
