Edmonton Marshes is a 6.4-hectare park on the boundary between the London Boroughs of Enfield and Waltham Forest, it is the largest park to be delivered in the Lee Valley since the London 2012 Olympic Games.

Edmonton Marshes is the larger sibling of Brooks Park and focuses on delivering an immersive experience of the ‘theatre of the water’. The brief for the park was to create a strategic flood attenuation asset and to make this a new parkland for Meridian Water, contributing amenity space, play and sports provision for 10,000 new homes and 30,000 people.

The proposal incorporates a number of infrastructure elements including existing electricity pylons and the canalised river edge. Flood management earthworks establish the future parkland planting and habitats, and a series of new routes across the park and along the Lea waterfront create urban connections. These retained and proposed components link the park into its industrial context, while the Marshes design strategy offers an adaptable framework for future communities to use in the coming decades.

The project benefits from the £150m Housing Infrastructure Grant secured by Enfield Council in 2019 as part of the Strategic Infrastructure Works (SIW) to recover the site from contamination and install new infrastructure. The project achieved detailed planning consent in March 2020. In 2021 Vinci Taylor Woodrow were appointed to deliver the parks over a four-year construction programme.
