Nick Knowles and the team undertake their biggest and longest build yet, constructing two buildings for the Grenfell community over several months to create spaces worth around £2million. With the aid of large construction companies, generous suppliers, volunteers and the Duke of Cambridge - who visits the site - the team starts by building a new home for the Dale Youth Boxing Club. The club started the careers of James DeGale, who won an Olympic gold medal in Beijing 10 years ago, and George Groves, current WBA Super Middleweight champion, as well as producing many national champions.
