Walthamstow Wetlands

Structural Steel Design Awards 2018 - Merit

Walthamstow Wetlands is Europe’s largest urban wetlands and expects to host 250,000 visitors in its first year. As part of the project to provide the facilities necessary for opening the site to free public access, two disused infrastructure buildings, the locally listed Engine House and the Grade II listed Coppermill Tower, have been adapted for visitor use, providing an exhibition space, an education room, café, toilets, and a viewing platform.

The structural works included a boardwalk entrance, new first floor and spiral escape stair in the Engine House, and a new viewing platform and staircase in the Coppermill Tower.

Judges' comment

The team has successfully given a nod to the former industrial heritage of the building through the use of steel in many manifestations to highlight wayfinding and new interventions throughout this sensitive conversion. The balustrading, made from simple welded plate elements, proves an effective unifying element to the balconies and external spaces.
