When you've already got a full-time job, taking on a property development is a huge extra commitment and requires nifty job-juggling. This week two sets of developers take on that responsibility, but they each have very different approaches. Julie Thomas and Lee Jones are both scientists with a love of detail so they want to do all their renovation work themselves. But a surfeit of enthusiasm coupled with zero knowledge sees them giving up every single weekend and evening for months on end as they struggle to modernise their tiny two-up, two-down in Bedfordshire. Meanwhile, in Norfolk, Heidi Sutton, the self-proclaimed "most impatient person on the planet" gets the builders in to get her bungalow renovated as quickly as possible. But she hasn't bargained on just how much work project managing alone can involve.
