Duplex + - Actual Architecture

The prototype includes a 2-story, 3-bedroom family dwelling with a full basement (with the option for a bedroom with egress window well), a 1-story, 1-bedroom home designed for aging in place, and a Flex Room that may be attached to either of the two dwellings, or to both. The Flex Room and its adjacent courtyard patio are central to the adaptability of Duplex+. With a multifunctional door connecting it to both dwellings, the Flex Room may serve as an additional bedroom with accessible bathroom for either primary unit, a fully functional efficiency apartment for a caretaker, a shared family room serving an extended family occupying both units, and an attached ADU for an unrelated renter. The Flex Room supports all forms of the modern family.

Where the typical duplex appears as a mirrored pair of identical dwellings residing uncomfortably next to one another and standing out from the neighborhood fabric, Duplex + projects the multiplicity of its supported dwellings. This visual heterogeneity combats the negative community perception of duplexes and other “Missing Middle” housing types – Duplex+ fits into and enhances the character of established neighborhoods. The design is compatible with a variety of lot types with different modes of access. The prototype can take advantage of a rear alley for access to concealed parking, but the relatively narrow building allows for driveway access from the primary street where required (the garage can be rotated 90 degrees for access from the side).

Designed for Aging-in-Place, and for Community Building

The concept supports aging adults who want to live adjacent to an adult child or caretaker, to live in a multigenerational complex, or to provide a supplemental source of income that makes it easier to remain in a home neighborhood as property values rise. An owner could downsize without moving, or an emerging developer could implement an adaptable design that responds to the specific demographics of the places they wish to enhance.

Aging-ready residential design begins with smooth, accessible movement throughout the property: from the parking area / garage to the entrance of the home itself, and from there to frequently used outdoor areas in the front and back. For the Duplex+, the shared patio is the key for outdoor living. Front and rear yard areas may also be shared or occupied separately by the two primary dwellings and the Flex Room. All dwelling units including the Flex Room have step-free entrances. The 1-bedroom unit has a primary bedroom on the ground level with a dedicated full bathroom with ample maneuvering room. Should the Flex Room be connected to the 2-story dwelling, it would provide an aging-ready bedroom with ensuite bathroom for that home in as well.
