Ambitious builds, the tightest of budgets and a desperate need for fresh ideas united the projects that Kieran Long and Piers Taylor followed on The House That £100K Built. Now, Piers is back to tackle a final set of challenges - it is now or never as the owners battle to complete their homes for good. Wajid and Anam from Burnley have now completed more of their ambitious house in their own luxurious style, but they are struggling to make the largest room, at the heart of their home, feel welcoming. Piers searches for an ingenious design solution to solve it. He delivers a radical idea inspired by a fashionable hotel. In north east Scotland, the dream Heidi and Steven had for a home of their own has become a reality. The seemingly impossible challenge here is to turn a pile of builders' rubble into a stunning garden that is safe to play in for just £1,000! Piers shows them an extraordinary piece of landscape architecture in Edinburgh which could inspire a breathtaking design.
