Circular Economy and the Built Environment: Zelfbouw in Amsterdam. Addressing Resource Scarcity through Architecture

The paper intends to illustrate the application of Circular Economy to the design of the built environment, with a focus on the Dutch case. CE is a flexible framework supporting the optimization of resource use through a global redesigning of production processes and supply of services, according to a model which involves the employment of waste as an input material for new production cycles; the sharing of physical assets; the virtualization of processes; the reuse of goods and materials. CE represents a promising option to design a sustainable built environment in the current condition of resource scarcity. In the Netherlands, CE is implemented in the urban development through a bottom-up, widespread planning approach, sustaining citizens in developing individual housing projects to build through zelfbouw - self-construction. Zelfbouw adapts circular methodologies, tools and strategies to implement innovative sustainable solutions, control construction costs and develop experimental forms of living. This process leads to a specific architecture, with peculiar characteristics: the investigation on this ‘circular architecture’ opens promising perspectives for the definition of new design strategies to deal with current conditions of resource scarcity
