Because garden design is so personal, there is no definitive list of the "best" small garden designers in London. Instead, look for consistent markers of quality: professional accreditation, awards, thoughtful case studies and strong client feedback.
When you review portfolios, concentrate on spaces that resemble your own — narrow terraces, roof gardens, compact courtyards or shaded town gardens. Pay attention to how designers handle levels, privacy, lighting and planting structure, as these are critical in tight urban plots.
At Jonathan Fort Design, our work is focused on precisely these kinds of spaces: carefully structured, richly planted small gardens that feel calm, practical and tailored to the architecture they sit beside.
