connecticut power plant to be repurposed by bjarke ingels group

Transforming connecticut’s Manresa Island

The unveiling of the vision for Manresa Island marks a significant milestone in the revitalization of Norwalk, Connecticut. Designed by the Bjarke Ingels Group (BIG) in collaboration with landscape architecture firm SCAPE, this ambitious project aims to transform a decommissioned power plant site into a vibrant 125-acre public park. Surrounded by water on three sides, the site will serve as both a recreational hub and a center for education and ecological restoration.

Originally, Manresa Island was home to the Manresa Institute, a retreat and recreation destination during the late 19th and early 20th centuries. However, in the 1950s, it was converted into a coal-fired power plant. With its decommissioning in 2012 following Hurricane Sandy, the area has begun to recover ecologically, showcasing birch forests and increased osprey populations. This revitalization sets the stage for the transformation into a public amenity that reconnects the community with its coastal heritage.

Adaptive Reuse and Community Hub by bjarke ingels group

Bjarke Ingels Group (BIG) and SCAPE, commissioned by local residents Austin and Allison McChord, is focusing on the adaptive reuse of the existing power plant structures in Connecticut. The plan of Manresa Island includes the preservation of key components, such as the boiler building, turbine hall, office building, and the iconic smokestack. These structures will be reimagined as a network of spaces designed for events, education, and recreation.

The eight-story boiler building will become a recreational facility featuring swimming areas and dining options. The turbine hall will be transformed into a versatile event space and speakeasy, while the office building will provide classrooms and laboratories for marine and ecological studies. An underground water channel will be uncovered, creating a scenic connection among the buildings.

SCAPE’s design for the park emphasizes ecological restoration and public access. New waterfront walking paths will encourage exploration and interaction with nature. The park will incorporate living shorelines, wetland restoration efforts, and tree canopies to mitigate extreme heat and flooding. These elements are essential for creating a resilient space that celebrates and protects the island’s biodiversity.

Manresa Island will feature a diverse array of outdoor spaces that promote engagement with local habitats. Highlights include a large green lawn, a public beach with views of the Long Island Sound and New York City, and pedestrian bridges for wildlife observation. The aquatic theme will be evident through outdoor thermal pools, a revitalized pier, and a boat launch, providing ample opportunities for water-based recreation.

Kate Orff, Founding Principal of SCAPE, emphasizes the importance of this project in connecting Norwalk’s heritage with modern, sustainable design. The vision for Manresa Island aims to create a benchmark for adaptive reuse of industrial sites, integrating ecological restoration and community access.

With a projected opening date of 2030, Manresa Island is set to become a year-round destination for the public. Planned activities will include swimming, kayaking, and various educational programs in partnership with local universities. The project represents a significant step toward a more connected, ecologically aware community, ensuring that Manresa Island is a space for learning, recreation, and environmental stewardship for generations to come.
