First Circular Economy Development

Park 20|20’s masterplan is the paramount example of applying the Cradle to Cradle Design™ Framework and Circular Economy thinking to a community-scale development.

Park 20|20 Master Plan,
Beukenhorst Zuid, Hoofddorp, The Netherlands

Located within a man-made cultural landscape of a Dutch polder (land reclaimed from the sea), the firm was engaged by Delta Development Group in 2007 to create a new model of sustainable development that implements the Cradle to Cradle philosophy holistically and at all scales—from the city to the molecule. To meet our client’s goal of creating the first full-service Cradle to Cradle®-inspired development in the Netherlands, William McDonough + Partners is designing an inspirational environment that stimulates the creativity and effectiveness of employees by creating safe and healthy places for work and recreation.

Responding to its unique cultural, environmental and contextual challenges, the award winning Park 20|20 master plan creates a mixed-use development that synthesizes the issues of access and mobility, connectivity, passive design, and integrated energy, water and waste management systems. The site, adjacent to Schiphol Airport, provides easy access to the region and beyond through air, rail, bus, and bicycle routes. Green zones, urban plazas, public gardens and canal boardwalks within Park 20|20 encourage a connection to the larger community. Each building’s size and massing is optimized for solar orientation so that these exterior green spaces and the building interiors are flooded with daylight. A model of holistic, closed-loop design, Park 20|20 will function as a dynamic environmental system that enhances the local community, its ecosystem and its economy.
