About This Plan

The Willow by Arbor South Architecture draws from the white farmhouses that dotted rural Oregon a hundred years ago. The 560-square-foot layout uses a 20-by-34-foot footprint that fits naturally into established neighborhoods where historic character matters.

Inside, the open floor plan centers on a great room concept. The kitchen runs along one wall with an island for extra prep space and casual meals. The bedroom has a long reach-in closet, and the bathroom features a 4-foot shower designed for accessibility. Standard 9-foot ceilings create a sense of openness, with a vaulted ceiling option available if you want more volume overhead. A covered front porch completes the farmhouse look.

The entire unit is designed for barrier-free access. No steps at the entry, no level changes inside, no tight doorways. If you're building for someone who uses a wheelchair or walker, or just want a home that stays usable as people age, The Willow handles that without making it look like a medical facility.
