Free Open Source Granny Flat House Plans

Jay Osborne’s Free Backyard Farmhouse ADU Plans are practical, compact and efficient with all the character of a restored farmhouse home. This variation has a ground floor bedroom and bathroom. The first floor bedroom can be built at the same time as the rest of the small house or added later as an addition.

Having a bedroom and bathroom on the first floor is practical if you want to use this as a granny flat. You can add the extra space later, or you can build the house as this larger footprint small house.

Alternately the rear addition can be an office.

This is just one idea for making the house larger, while still retaining historical proportions.

This plan also shows the option of putting the house on a basement. If there is no basement, the space under the stairs adds storage.

There are alternative plans available. This variation shows the stairs making an L. The plan above shows the stairs in a U.

There is also a modification with the staircase easier to build and adapt to Canadian codes. “By making it an L shape, this staircase changed the layout of the main level. So it’s now more open.”

The bedroom suite is like a simple addition to the main house. It could be applied to any of my designs. So I may later make some stand-alone drawings for it. That way, you can add this first-floor bedroom suite to any one of my houses— or any of your own.

This opens up the downstairs, like more current homes. In the original design the living room could have a door, like older homes. This made it a more private guest bedroom.  Both plans are available; with the original stairs and separate living room and with the stairs reoriented and a more open downstairs floor plan.

As these plans are completed, they will be available to download free on www.freefarmhouse.com.
