Paul had returned home and was also back to work at a dedicated builders’ merchant that serves the Pinewood and Shepperton film and TV studios, but had been sleeping in the dining room for three years.

National construction charity Band of Builders (BoB) answered a call for help from Paul Kitterman, who was left paralysed from the waist down in 2021 because of a spinal abscess.

The team at Bob called for volunteers for the project to its 50,000-strong community of supporters and corporate supporters, including DEWALT, the project's headline sponsor.

The charity also approached its corporate partners for materials for the project, which was its 43rd project, from suppliers including Jewson, Ibstock, and Forterra.

Other suppliers included: Reconomy, SIG Roofing, CTD Tiles, Ideal Bathrooms, Minster, Catnic, PowerCor Ltd and Ralph Plastering.

More than 25 tradespeople from across the UK volunteered their time for free to build the extension in three weeks for Paul, who says having his bedroom for the first time in years has been a life-changing experience that means he can finally get a good night’s sleep again.

Speaking about the new extension, Paul and his wife, Sasha, said they can’t thank enough all the Bob volunteers and the companies that donated materials.

“This project has changed our lives,” said Paul. “This extension gives me my dignity and privacy back, as I now have a shower, toilet facilities, and a bed.

“I’ve had a great night’s sleep every night since the project was completed, and it’s all down to the incredible, selfless tradespeople who gave their time for free to help change our lives.”
