 Houses in PUDs often include access to a large shared open space surrounding the house as well as a smaller private yard.These large protected open spaces are created by the layout of the buildings and are intended for use by all residents of the developments.Different housing types (single-family, two-family, multiple-family) are often mixed rather than separated as is done in conventional development

Street patterns are one of the most important elements in establishing the neighborhood character of a residential community.
