This article explores the relationship between design methodologies and the scaling of participation in cities. The article recognizes that the scaling of community-led informal settlement upgrading is a central concern in the broader debate on scaling participation, and it interrogates the potential contribution of design methodologies in connecting localized, community-led upgrading initiatives outwards and upwards. We discuss these ideas by drawing on our own experience of devising and facilitating a number of participatory design and planning initiatives titled Change by Design with the non-profit organization Architecture Sans Frontières – UK (ASF-UK). Reflecting on this experience, we argue that the inclusion of a design-based, city-level perspective in localized upgrading initiatives can be a powerful conceptual and practical tool to support horizontal, vertical and deep scaling; and we highlight the importance of constructing this design tool in an embodied and situated manner, so that scaling processes remain firmly grounded in everyday lives and experiences.

本文探讨了设计方法与城市参与规模之间的关系。本文认识到，社区主导的非正式住区升级的规模化是关于扩大参与度的更广泛辩论的核心问题，它探讨了设计方法在向外和向上连接本地化、社区主导的升级计划方面的潜在贡献。我们通过借鉴我们自己在与非营利组织 Architecture Sans Frontières – UK (ASF-UK) 一起设计和促进一系列名为 Change by Design 的参与式设计和规划计划的经验来讨论这些想法。反思这一经验，我们认为包含基于设计的，本地化升级计划中的城市级视角可以成为支持横向、纵向和深度扩展的强大概念和实践工具；我们强调以具体化和情境化的方式构建此设计工具的重要性，以便扩展过程牢牢扎根于日常生活和体验中。
