Abstract The Seoul Metropolitan Area (SMA), South Korea, is a region where two distinct types of suburbs exist today, new towns developed by the public sector and suburban communities by the private. This article comparatively analyzes , a state-led new town, and Suji, a market-led community, in the SMA in terms of two key foci. The first is urban form characteristics, which include land use pattern, street pattern and circula- tion, public open space, built form pattern, and control. The other is residents’ livability and satisfaction, which include public transit service and use and neighborhood satisfaction. Findings suggest that Bundang outperforms Suji in all aspects, demonstrating the benefits and effectiveness of planning in shaping suburbia, while Suji shows many negative signs of sprawl.
