Alistair and Karen hope that building a family home in County Antrim, Northern Ireland, could be the key to a mortgage-free life. Alistair grew up close-by and wants his son to have the same childhood he had, surrounded by farmland and playing in the stream. The design must meet the needs of an uncertain future - Alistair was recently diagnosed with MS so they have designed the home with wheelchair access in mind. Kieran Long and Piers Taylor must hunt out ingenious ways to improve their design so the couple can get the best house possible on their budget. Their single storey home has three distinct parts but Piers quickly discovers the most expensive bit is a glass section in the middle, which the couple is only using as a corridor! He must help them make the most of every part of their home while Kieran looks for design tricks to improve key areas. He inspires them with a home that uses pocket doors rather than traditional swinging ones and proves that increasing the space around a kitchen island makes an enormous difference to how successful it is, and costs no more. As the costs begin to rise, Alistair and Karen are disappointed with how their £10,000 kitchen looks in the space. Piers comes up with a ‘peg board’ idea that looks like it could have cost thousands but was only £60! Having invested so much financially, physically and emotionally, Alistair and Karen are desperate to get out of their caravan and into their new home, but will they have managed to capture the magic of the plot and create a home for the next generation of their family?
