Young, glamorous couple Sarah and Tristan have just brought their first house together, in Stevenage, but it has come with an outdated, 20-year-old garden that needs injecting with the modern, luxury style they love. The couple have a budget of £5,500, but Sarah has expensive tastes, and because she often works in hospitality at the Chelsea Flower Show, where she gets most of her garden design inspiration, she has set the bar high for Arit and Charlie. Can they match Sarah’s deluxe vision?
