The DIY guru attempts to build an affordable eco-friendly home in 60 days with a limited budget.

The team installs the rainwater-harvesting drainage system, which supplies the toilets, washing machine and dishwasher.

With the block-and-beam floor nowhere to be seen, the team tries to come up with a solution to allow the bricklayers to begin their work.

To improve the house's energy efficiency, a damp-proof membrane is laid to prevent heat loss and thermal blocks are used instead of concrete increasing, the house's thermal efficiency.

The joists for the first floor are installed along with the timber frame that forms the basis of the roof. And the team try to eat doughnuts without licking their lips.

Polyurethane wall insulation is added, and the team considers installing supportive wooden pegs called 'nogs'.

The roof slates and solar panels are fitted to the house, and the team learns the property will be the most energy-efficient in the Fens.

The house starts to take shape as the exterior cladding is fitted and the under-floor heating is installed.

The rooms are boarded in preparation for plastering, and a special water tank becomes the latest environmentally friendly addition to the project.

With the deadline looming, there's still a lot to do. Tommy and the team work on the fitting the staircase, tiling, electrics and plumbing in a bid to complete the project.
