# John Marshall Associates
John Marshall Associates is a family-run structural engineering practice based in Forest Row, serving clients across London and the South East. With over 40 years of combined experience, the firm specialises in structural design and engineering across residential, heritage and commercial projects.
The business handles diverse work including new builds, major refurbishments, listed building restoration, and eco-friendly construction initiatives. John Marshall, the company director and MIStructE-qualified engineer, works closely with architects, builders and developers to deliver cost-effective, practical solutions. He manages all aspects of projects from initial design through to liaison with local authorities on behalf of clients.
What sets John Marshall Associates apart is their genuine family business approach. Rather than corporate detachment, they prioritise personalised service and build long-term relationships with clients. Their portfolio demonstrates real expertise—from a Grade I listed Friends Meeting House in Lewes to substantial town house refurbishments in Belgravia and heritage manor restorations in Sussex. This blend of complex heritage work alongside contemporary new builds showcases their technical versatility.
The firm values integrity, quality craftsmanship and innovative problem-solving. Their longevity—operating since 2002—reflects client trust and repeat business. Supported by Jeanette Marshall's administrative expertise, the team maintains efficient, professional operations while keeping the personal touch that characterises a genuine family enterprise.
