Episode 4

Every year 20,000 people in the UK make the bold decision to build their own home and we're following some of them as they go from foundations to finishing touches.

All our self-builders are aiming to build their dream home that's perfectly suited to their way of life and their wallets but each build's a rollercoaster ride packed full of trials and tribulations.

On today's programme, will Michael Howlett succeed when it comes to building two eco-houses out of straw in Pembroke Dock or will this ambitious project be the final straw? Plus the luxurious Hampshire self-build disguised as a collection of farm buildings, and presenter Simon O'Brien is hung out to dry while hanging a door at building college.
