Charlie and Flo go head-to-head with a budget of £4,000 to design a garden that takes inspiration from Crete, where Natalie and Matthew spent their honeymoon. Their L-shaped garden offers challenges for the designers, who also need to consider the couple's young toddler, Arthur.

Charlie hopes her Greek-inspired planting scheme, pergola and water feature will appeal to the couple, while Flo is banking on the taverna-inspired seating area with colourful Mediterranean plants to sway the decision in her favour. But has Flo remembered a vital ingredient that Charlie may have overlooked?

Helen and John from Port Talbot dream of a Cornish-inspired plot. Helen was born in Cornwall but moved to Wales as a child. The couple are keen to bring a touch of Helen's home county to their current property. With £5,000 to play with, Charlie and Chris turn this troublesome clay-soiled garden into a Cornish coastal haven.
