Incrementalism is a growing movement within multiple design disciplines that approaches design with sustainable, social, and resilient aims structured around participatory, infrastructural, and phased approaches to design. Carefully considered structural and independent infrastructural frameworks allow infill and accretion according to the demands and needs of individuals and communities. This paper outlines the theories, case studies, and conditions driving incrementalism. My research has informed my project proposal for an incremental upgrade of a slum located in Jakarta using a phased, soft infrastructural, resident facilitated upgrade and development strategy creating new housing units, productive landscapes, and urban form. Incremental development will foster the social aims of my project, while affordably, equitably, and efficiently upgrading the standards of living for slum dwellers within the Waduk Pluit community.
