Our 30×40 duplex model plan is named for the mountain town in Oregon, Sister. Sisters is the venue of the largest annual outdoor quilt exhibition in the world. The architecture style of homes in Sisters inspired a western cowboy design theme, providing identical 2-story units with 4 bedrooms and 2.5 Baths. Each unit has a one-car garage and a covered back porch for outdoor family gatherings. There is also a covered front porch for sitting and visiting with neighbors. The living space of each unit is under 1,650 SF. If mountain cowboy is not your style, we could draft a modification to this model for a traditional curb appeal. We could also draft the plan as a single unit without the sister unit attached.
