The Barn Garden at Serge Hill is about 25 miles north of London. It has been created by Tom and his family over the last 30 years and is periodically open to groups by appointment. The garden is part work in progress, as all gardens are, and part experiment - a bit new and messy in some places and getting quite middle aged in others. It is very much a home and not a show garden. If there is one idea that holds it together it is about trying to anchor a place, about creating a focus for living in a landscape that is slowly losing its weave and detail.

Since 2020, Tom and the team have developed the Plant Library, a unique and extensive educational resource for anyone interested in plants and planting design. Located adjacent to the Barn Garden, on the site of an old orchard, the Plant Library is laid out on a grid system and contains over 2,000 varieties of predominantly herbaceous plants. Conceived as an interactive, walk-through catalogue, the Plant Library allows plants to be studied from all angles. Varieties and species can be compared directly, and combinations of form, texture, foliage and flower observed and appreciated over time.
