In north London, Ian and Rose have recently moved into their new basement home and are hoping to create a wildlife-friendly space. Currently it is a building site - neglected by previous owners. They also need expert advice since their plot is surrounded by four large trees blocking a lot of natural sunlight. Even if they manage to clear their space, can they ever create the garden of their dreams? They are in serious need of help and advice, but can Monty set them on the right track? Meanwhile in Stockport, Jo and Steve's equally large garden has become a dump as they build a new extension. The couple lead busy working lives with Jo travelling the globe as an air hostess and Steve working long night shifts at a bakery. Their longed-for dream is a haven to relax and get away from it all in. The problem is Jo has so many exciting ideas about what she wants to do and Steve is rather more pragmatic. Can Monty help the couple work out the best of their ideas and give them the advice they need to get going?
