HTA’s Planning team led the creation of the ‘Star Hill to Sun Pier’ Supplementary Planning Document (SPD) for Chatham Intra, a historically significant section of the Medway waterfront. Commissioned under Historic England’s High Street Heritage Action Zone programme, the SPD sets out a robust framework for future growth that protects and enhances local heritage while enabling sustainable regeneration. Our approach was shaped by deep engagement with the local community, Medway Council and Historic England. Through workshops, exhibitions and a final placemaking symposium in April 2023, we gathered public insight that directly influenced the strategy’s development and priorities. The SPD was formally adopted in 2024. The final document offers a clear and practical guide for decision-makers, developers and designers, enabling delivery of a high-quality urban environment that celebrates Intra’s layered history. Planning policies within the SPD support biodiversity, sustainable transport, and new development that is responsive to the existing character and identity of the area. It is a blueprint for heritage-led regeneration — one that allows for change while safeguarding what makes Chatham Intra special.
