Debi and Des live in Enfield, London. Their beautiful family home has a generous urban plot, but it sits on a massive slope that is currently only used as an outdoor exercise space for Des, whose studio gym sits at the end of the garden. Debi would like a space she can relax in after a hard day's work, but the real dream would be transforming the plot into a family space for everyone to enjoy. Having stared out at their uninspiring plot for years, Debi and Des are desperate for a solution.

Stepping up to help are award-winning garden designers Oliver Bond and Helen Elks-Smith. Oliver has got big ideas on how to identify and define new zones in the space, whilst Helen finds an unexpected sweet spot right in the heart of the plot. Using virtual reality, both designers pitch their radically different approaches. Either one would be a perfect fit, but which will the couple choose?
