Tommy Walsh and his three-man building team clear out and demolish an old dilapidated shed in Essex to prepare the way for his Ultimate Workshop.
The construction of the timber frame walls gets underway using a 'Bolt On' modular technique.
Tommy enlists the help of an expert joiner as he tackles one of the more difficult parts of his project - the roof - which also features a large dormer and attic.
Tommy and his team get to work on cladding and insulating the walls for his workshop, but not everything goes according to plan. Can they resolve the problem?
Tommy adds the finishing touches to the workshop interior, before demonstrating how to install ceiling insulation, lighting and double glazing.
