Passionate gardener Sonia is finding her hobby more of a challenge since her recent eye condition has worsened. Hoping for a space that brings back memories of her favourite cottage garden, Lee and Charlie battle it out to win her favour. This time, it's Lee's design that wins, but his new garden must include Sonia's hexagonal hut, also known as the Gin Palace, and her hot tub. Lee decides to complement them with another hexagonal water feature and a pergola that covers the hot tub! The real stars are the plants, which are added to appeal to Sonia's sense of smell and touch.
