These housing 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 highlight a range of innovative configurations (including several oriented to shared courtyards), 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.

The prototypes are based on site configurations common in different parts of the city, such as those of close-in neighborhoods where infill sites are typically in increments of the 50'-wide lots established by Streetcar Era platting; and the very different sites typical in Outer East where lots are larger but disproportionately deep.
