Westfield Southcenter Mall, located in Tukwila, Washington, is one of the largest malls in the nation, and like many malls, its aging retail spaces and surrounding strip malls are becoming less viable. With rising housing costs and a growing regional population, it is clear that spaces like Southcenter must be transformed into affordable, mixed-use districts that can provide housing, vibrant community spaces, and accessible transportation options. This project explores how Southcenter Mall can be redesigned using New Urbanist principles to foster a thriving community. Using site visits and global case studies of recent successful mall redevelopments, it analyzes the current shortcomings of Southcenter Mall and proposes a more successful mixed-use alternative. The final deliverables include a 3D model mock-up of a revitalized Southcenter that includes affordable housing, ground-level retail, and an overhauled transportation framework prioritizing pedestrians and cyclists.
