The new run of the iconic property show continues. Kevin McCloud follows more of Britain's most ambitious self-building projects, as intrepid individuals attempt to design and construct the home of their dreams. It's tough falling in love, especially when it's with a 150-year-old rickety barn that's in danger of keeling over. But HR director Sarah and technology director Pip are smitten. Never mind the many planning restrictions, or that it sits on the site of a scheduled ancient monument; Sarah and Pip are determined to keep its spirit while at the same time transforming it into a sleek and modern five-bed home, with space for their expanding pet family... a hugely challenging balancing act. With a budget of £420k, they try to keep as much of the original structure as possible to save on costs, but the fragile building starts to unravel almost as soon as work begins. Old brick columns, walls and an entire timber gable end come tumbling down, too unstable to withstand the identity change. The barn, it seems, is in danger of becoming a terrifying money pit. Under pressure on all fronts, and not always seeing eye-to-eye on what the end result should be, Sarah and Pip draw on every ounce of resolve to try and make it through...

The new run of the iconic property show continues. Kevin McCloud follows Britain's most ambitious self-building projects, as intrepid individuals attempt to design and construct the home of their dreams. Kevin revisits architect Graeme and Melanie, who had huge ambitions for their new home in Hackney; a comfortable haven for themselves and their teenage daughters, Isla and Indi. They wanted the house to celebrate and cement their new blended family, formed following the loss of their own partners. The only problem was where they wanted to build: on a tiny twin garage plot bought for a whopping £275,000, on a traditional Victorian terraced road. Graeme came up with an unapologetically modernist bright red design. Inside, it was to be cleverly laid out to maximise?space vertically. Despite the challenge of excavating four metres down in a tight urban site, the schedule was set at just 12 months, with an equally tight budget. But a catalogue of challenges quickly hit Melanie and Graeme, from the basement contractor withdrawing due to skyrocketing material costs, to huge increases in mortgage rates draining the budget. And as the project neared completion, a final bombshell in the basement blew their schedule off course and put even their hopes of living in the house in jeopardy. Eighteen months since his last somewhat gloomy visit, Kevin returns to see if Graeme and Melanie are finally out of their hole. Do they now have the beautiful home they originally envisaged?
