Cottage Housing
Contents
Introduction
Cottage Housing is generally defined as a grouping of small, single family dwelling units clustered around a common area and developed with a coherent plan for the entire site. They have gained popularity in recent years as a type of infill development on small sites, within existing developed areas. The cottage units may have other shared amenities. The shared common area and coordinated design may allow densities that are somewhat higher than typical in single family neighborhoods possible while minimizing impacts on adjacent residential areas. As a result, cottage housing can offer its owners a quality living experience that is less expensive than traditional single family housing. It also offers a degree of privacy and some of the benefits of single family housing combined with the lower cost and maintenance of attached housing. The clustered arrangement can contribute to a sense of community. Even so, its departure from existing patterns and its higher density have encountered resistance in some communities.
