House 23 is located atop a hill overlooking the retreat valley and consists of 2 separate buildings connected by a redwood deck and covered breeze-way which affords some nice outdoor dining experiences.

One building contains a full kitchen, a bedroom with queen bed and an indoor bathroom with shower/bath and composting toilet. The interior walls are soothing colors, and the entire cottage is made with non-toxic materials. The floor is marmoleum, a soft and durable substance made from recycled paper and resin.

The second building consists of a large practice space with pressed adobe floors sealed with environmentally friendly oils and high windows for raking light.
