As part of this typology, we aim to curate a gallery of designs that, collectively, reflect the following:Accessible units. We seek designs that meet accessibility requirements. Some people require a single-story accessible design. We recognize that accessibility depends in part on site conditions, which vary for each lot where these plans might be used. Still, single-story units designed with accessibility in mind meet the needs of some residents. We also encourage plans that, even if not fully accessible, include universal design features and are visitable for at least some units. For stacked housing forms, consider the accessibility of ground-floor units.Range of unit sizes. To serve various household types and sizes, we seek designs with one, two, and three bedrooms. We particularly encourage designs with at least two bedrooms, since larger households and families with children may need multiple bedrooms to meet their needs.Single- and multi-level designs. Given the accessibility and size goals above, we anticipate selecting designs that vary in terms of arrangement of space vertically and horizontally.Flexibility. For types like single detached units and side-by-side duplexes, we welcome submissions of designs that can be modified for multiple unit sizes and configurations where feasible. For example, a one-bedroom base design could include an option to add a second bedroom that does not modify the remainder of the plan. Such design options can be considered as part of one pre-approved plan.Garage and storage. ADUs and dwelling units smaller than 1,200 square feet do not require off-street parking requirement. Other housing generally requires one space per two dwelling units. Though not always required, we welcome submissions of designs with and without attached garages. We also welcome (but do not require) thoughtful inclusion of bike storage and other amenities.Amenity spaces. In the updated Neighborhood Residential (NR) legislation, Section 23.44.110 includes requirements for amenity area. While full compliance with this standard requires a complete site plan, we encourage designs that offer a clear pathway to compliance and welcome designs with open space features including porches, balconies, and roof decks.Repeatability. As noted in the typology above, several housing types could be permitted in multiple configurations. For example, a single detached unit could be permitted once or multiple times on a site; a stacked duplex could be permitted once in a backyard or two to three times on one lot as a four- or six-unit development project. We welcome designs that consider these options for configuration in their submission.Submissions will be assessed on the following criteria:Affordable to construct. Designs that can be constructed easily, quickly, predictably, and at relatively lower cost.Energy efficient. Designs that include green building and design features, passive heating and cooling, renewable energy generation, etc.Repeatability. Designs that can be configured well in multiples on a site.Easy to live in. Efficient, comfortable unit design and layout.Creativity. In form and designContextual design. Potential for compatibility with common architectural contexts and privacy considerations in relationship to common lot configurations in Seattle residential neighborhoods.

Include sketches that help reviewers understand how the design could be used in different contexts or configurations, such as:How the design can be used as standalone home in the rear yard (preserving an existing structure) and/or in a series of multiples (if the entire site is redeveloped)How the design can be used on mid-block and corner lotsViability on a range of lot sizes from roughly 4,000 to 8,000 square feet, as applicableAssumptions about minimum setback to property line and distance to other dwelling units on the site, if applicableOptions the design includes, such as:Roof formAddition of a bedroomWindow packagesMaterial variationsOpen space options (e.g., porches, balconies)Selected plans subject to the Seattle Building Code (SBC) will also need to include:Structural design performed by a licensed structural engineer in the State of WashingtonMandatory accessibility requirements, for projects with four or more stacked units
