St Mary's Island Masterplan

Chatham, UK

St Marys Island0074

project overview

A significant masterplan on one of Europe’s largest regeneration sites

St Mary’s Island is Britain’s only strategically planned island community, creating a modern suburb with a strong maritime character. Across 150 acres, the scheme seamlessly integrates 1,700 homes with shops, a school and other community facilities, public open spaces and a marina.

Over 20 years in the making, our masterplan strategy is an exemplar of sustainable brownfield development. Our thoughtful masterplan creates a strong identity appropriate to the site’s history as a naval dockyard, for a thriving community of residents, businesses and visitor attractions.

site history

Exemplar reuse of a brownfield site for much needed homes

Dating back to 1547, the original dockyard has been the site of over 400 years of shipbuilding for the Royal Navy, including the building of Nelson’s flagship, HMS Victory. Resulting in a heavily contaminated plot which underwent extensive remedial works leaving a flat, virtually featureless, site.

With a strong demand for affordable homes in the region, the site underwent extensive remediation and structural landscaping to make it suitable for development. Our involvement began in 1999, to enhance the site’s value and address the need for more homes on the island, we were commissioned to review the original masterplan.

Our development of the original masterplan enhanced the site’s value, addressing the need for more homes on the island through the production of a design code. We established principles for every part of the masterplan to inspire quality of any and all future development.

We then went onto the detailed design and delivery of sector 5 of the masterplan, the award winning Fishing Village and sectors 7 / 8 known as North Shore. Following this, we were selected to complete the final phases of development (sectors 10, 11, 13 and 15) at the western end of St Mary’s Island after winning a two stage architectural competition.

Masterplan development

A navigable masterplan linking back to the wider community

We were appointed to review the original masterplan, with a vision to create good quality, sustainable living for the local community. Addressing typical restraints associated with a waterfront area, whilst also linking to the wider context of surrounding areas, increasing legibility and providing a sense of place and identity.

We established a masterplan that was capable of flexing with changing needs and requirements across each plot or 'sector'. The layout of the masterplan was designed to maximise the waterfront views and includes viewing corridors serving as vistas to the Marina and River Medway.

The identified dominant site themes were the central landscaped bunds, which was to act as the "spine" of the development, the loop of the highway system, pedestrian network, hierarchy of green open space and the location of the homes for best access to community facilities.

We prioritised pedestrians and cyclists, establishing a pattern of movement around the masterplan which minimised car dependency. The inclusion of home zones assist in traffic calming without the need to use physical features, improving the safety of pedestrians and cyclists without compromising on the design code.

We developed three character areas to create cohesion between each sector through the relationship between the buildings and the streets, the building styles, different densities and heights as well as materials and landscaping. Zone one (riverside maritime) covered sectors 7,8,9 and 13, zone two (upnor view) was sector 15 whereas sector 11 was covered by zone three (dockside).

Design code

Building legacy for all future development

Our masterplan design code focuses on five key principles of placemaking; cohesion, hierarchy, place, ownership and memory - established to assist designers and developers with future phases and create one unified identity. It takes into consideration the Medway Housing Design Standards, Kent Design Guide, local planning guidance as well as the requirements of St Mary’s Island Residents Associate and the Chatham Maritime Trust. Each sector has special civic character, interest and unity, such as parks, squares and promenades. Designed to integrate with the wider masterplan for the island, transport links and infrastructure.
