Big Dreams, Small Spaces follows two people attempting to change their lives and landscapes. We meet Alex, who has the ambitious dream of turning her tiny, 32-square-meter new-build backyard into a mythical enchanted forest on a tight budget. We also meet Ross, who is looking to rebuild his life by tackling a completely neglected, overgrown allotment plot to create a productive and peaceful space. Monty Don, the trusted authority on gardening, steps in to provide essential advice and help them through their challenging transformations. Watch as both gardeners complete their projects, with Alex successfully creating her magical, winding woodland and Ross achieving his dream of an orderly, productive plot complete with a beloved pub shed, providing him with a renewed sense of confidence and hope.
