Piers Taylor and Kieran Long are concerned that the cheap materials they plan to use could compromise the building's success, so Kieran shows them the latest in contemporary homes, and Piers helps them achieve a good look for less money. However, a major structural problem emerges that threatens the future of the project. Will they even be able to complete the home that they had such big dreams for?
