Circular urban design is vital for developing the urban environment amidst intense urbanization, resource depletion, and climate change. Recent studies indicate that using urban space effectively is a necessity to promote circularity in the built environment. Yet, so far, discussions on the use of space within the circular economy have hardly shown its value beyond financial terms and enabling the circularity of buildings. To better capture the non‐financial benefits and costs, this study uses a plural value perspective by means of a public sector circular business model lens. The model is applied to three cases of urban space use in the city of Amsterdam. In these cases, space is used for temporary storage and handling to facilitate material reuse in urban area maintenance and (re)development projects in outdoor public spaces. Our findings demonstrate that (temporary) use of urban space is a crucial resource to store materials and enable material circularity in outdoor public spaces. The findings show that more permanent use of urban space provides opportunities for value chain collaboration and professionalization of storage and handling, whereas shorter use of urban space can be utilized for temporary storage to orchestrate the reuse of materials locally. The (temporary) use of urban spaces enables reuse, repurpose, refurbish, repair, and/or remanufacture of materials and products applied in outdoor public spaces and can create public, social, environmental, and economic value. The findings guide project stakeholders, urban planners, and policy makers on how to unlock the value‐creating potential of (temporary) urban space use to create circular outdoor public spaces. ...

This research examines the impact of participatory planning on the realisation of public interests in urban regeneration, establishing an analytical framework to assess how participation shapes spatial transformations. Focusing on Taipei, it investigates the roles of public and private actors, statutory participatory processes, and resulting spatial changes.

Two primary objectives guide the study: proposing a framework for assessing participatory processes and spatial outcomes and analysing Taipei’s diverse urban regeneration approaches—private-led, public-led, and social housing as a regeneration strategy. Six key questions explore literature on participation, evaluation indicators, policy evolution, implementation practices, spatial influences, and the effects of statutory methods like public hearings.

Grounded in communicative planning thought, the research introduces the Inclusive Radar, adapted from Fung’s Democracy Cube, with axes for Participant, Communication and Decision-Making, Authority and Power, and Spatial Transformation. Employing case-study methodology, it integrates semi-structured interviews, site visits, meeting notes analysis, and cross-case comparisons.

Findings reveal property-owning stakeholders’ dominance, marginalising non-property-owning stakeholders despite participatory processes. Private-led projects prioritise procedural compliance, public-led ones mediate via community planners but hinge on owners’ consent, and social housing fosters distrust through ambiguous participation. Overall, structures favour property rights, sidelining broader public interests like accessible facilities and green spaces.

The study concludes that pre-assumed public interests restrict participation, with policy shifts emphasising property rights transfer and real-estate incentives. The Inclusive Radar offers a multidimensional tool for future applications, advocating policy reforms, capacity-building, and stronger public interest definitions to enhance inclusivity.

Based on the understanding of the built environment as result of competing claims on space that must be resolved via recognition, fair distribution of burdens and benefits of our human association, respect and care for the planet and just procedures to decide on those claims, Spatial Planning and Strategy is a chair in the Department of Urbanism within the Faculty of Architecture and the Built Environment of the Delft University of Technology, committed to helping create sustainability, resilience and spatial justice through the implementation of the New Urban Agenda, the Paris Climate Agreement and the European New Deal, among other frameworks. This commitment is reflected in activities, events, and courses. We are concerned with knowledge about the formulation, implementation, and evaluation of strategic and urban planning tools – visions, strategies, plans and programmes. ... Read more

This study examines the issue of publicness and the practice of public participation in urban regeneration through municipal-led social housing as an approach to urban regeneration. The study examines the case of Taipei through the project process and deliberations to understand the communication and decision-making patterns of the project, which includes an analysis of who is eligible to be a participant, who is ignored, and the extent to which these participants are given decision-making power. As well as, what the public interest discussions are for these final urban regeneration projects. This study found that the participatory process, in this case, was quite ineffective. This is because the communication of the public interest at the outset led to conflicts between the municipality and the residents. And when the participatory process could not reach a consensus within a certain time frame, the one with the final decision-making power (the municipality) made an authoritative decision instead of continuous public communication. ...

Taiwan’s social housing has concentrated on the physical provision of housing and pays little attention to questions of social inclusion in neighbourhoods. However, placemaking practices in other countries have triggered a flurry of experimentation in social housing in Taipei. We evaluate the performance of placemaking efforts aimed at enhancing tenant participation in social housing management. The rapid and selective transfer of social housing policy approaches from the West has led to problems in implementation and management. However, we found that community placemaking involving planners as facilitators fostering partnerships significantly enhances tenant participation in the provision and management of social housing. ...
