2+3 Fiveplex
Any Typical Single-Family Residential Lot
The 2+3 Fiveplex is a conceptual proposal for a 5-unit residential development on a single-family zoned 50’ x 100’ lot. It is comprised of two 2-story detached structures united by a central garden courtyard; the Fiveplex features a diverse unit mix, including two family-sized units in the front building and three smaller units of varying sizes in the rear building. Each unit is carefully designed with private outdoor space and access to ample light & fresh air.
For the sake of affordability, it is envisioned that the 2+3 Fiveplex can be constructed with conventional wood framing. The simple yet bold gable roof form of the front building assists the development in fitting in with existing single-family neighborhoods, while the shed roof of the rear building slopes down to 18’-0”, respecting the neighbors behind.
