Baker Creek ADU

ADU House Plan with Farmhouse Charm

This Modern Farmhouse ADU originally accompanied a larger home, but we’ve also decided to offer it separately. The exterior is all modern farmhouse, and the floor plan is perfect for a shop, studio, or even permanent residence. There is a full bath, bedroom with private porch, and an eat in kitchen with full set of appliances. The strong trend to downsize will not stop anytime soon. Anyone looking to place a minimum footprint on the environment can appreciate this classic example of downsizing.  The Baker Mini House plan also offers a particularly carefully value engineered structure that will over perform in the energy conservation department and come in under budget

This design is available to purchase and build everywhere except for the State Of Oregon.
