In the second episode of DIY SOS's biggest and longest ever build, the team are attempting to build a two storey flexible use centre that can be used by the community however it decides. Research indicated that there wasn't enough low cost space that different community groups could use in the area so with the help of generous construction companies, suppliers and volunteers, the DIY SOS team attempt to do what they can to help.The team are joined by the Duke of Cambridge, who previously helped out on another build in Manchester for veterans. The Duke meets local residents and talks to firefighters who were amongst the first responders on the night of the tragic fire.
