The housing prototypes of this section are intended to serve as a problem-solving tool to help improve the design of medium-density infill housing projects, particularly in the R2 and R1 multidwelling zones. The prototypes highlight medium-density housing types and configurations that are suitable for common infill situations, meet City regulations and design objectives, and are feasible from a market perspective. They illustrate solutions for common infill design challenges such as balancing parking needs with pedestrian-friendly design and providing usable open space while achieving density goals. They are also intended to help broaden the range of housing types being built in Portland by presenting innovative configurations, with a particular focus on arrangements conducive to ownership housing. The prototypes continue characteristic neighborhood street frontage patterns by featuring house-like building volumes along street fronts and by providing opportunities for landscaping.
