In The House That £100k Built, Kieran Long and Piers Taylor helped self-builders as they embarked on the biggest gamble of their lives, building a home from scratch for less than £100k. This time, Kieran and Piers are bringing their experience to a different problem - existing homes.

With the tightest of budgets, big hopes but little or no experience, each homeowner is desperate for help. With all sorts of problems to solve, Kieran and Piers use their architectural expertise and ingenious design ideas to help homeowners to turn tired houses into exceptional homes. But with design dilemmas at every turn and their life savings at stake, will these homeowners manage to create the house they've always wanted, but believed they could never have?

Ben and Mita fell in love with their warehouse apartment due to its central location and lofty style, but two children later they've run out of space, can't afford to move and are at a loss as to what to do. Piers and Kieran need to fundamentally change the way the couple perceive their home and encourage them to adopt an ambitious architectural solution. With some tough financial decisions to make, will the couple finally transform their chaotic flat into a tranquil family home?

Graham would love his partner Gabrielle to move into his house, but currently she says she'd rather use a chamber pot than his outdated bathroom. Meanwhile the kitchen is the last place they'd want to enjoy a romantic meal. With just £10k to fix both problems, Piers must come up with a series of solutions for creating luxurious spaces, but will his architectural tricks of the trade persuade Gabrielle to finally move in?
