Alan Titchmarsh and his team reveal how adding water can transform any size garden, creating two incredible water gardens, one outside and one inside. In Kent, Alan, Frances Tophill and David Domoney build a stunning outdoor space in a small plot featuring three different but equally spectacular water features. Meanwhile, Katie Rushworth reveals how to build an indoor water feature that can transform a bare corner of a home.

Alan Titchmarsh and his team are in the Wirral to create a jungle inspired outdoor space for Conrad and Pauline Toohey, who have dedicated their lives to helping others, including severely disabled son Keiron. Their garden is so overgrown some of the family have not used it for decades, so Alan and the team transform the garden into a tranquil retreat with a pond to attract wildlife, and covered pergola surrounded by tropical planting. Meanwhile, Frances Tophill is in Cornwall to visit the UK's only outdoor jungle at the Lost Gardens of Heligan, where she helps head gardener Cindy plant some pond lilies.
