The Farmhouse Bench is designed to work with this Farmhouse Table, but there is no reason you could not modify the dimensions or use it as a coffee table or outdoor bench. If you plan to build the Farmhouse Table, starting with the bench will give you a chance to test out your skills on a smaller version.
For those of you who have a pocket hole system, you can use the pocket holes to build your bench seat separate. You can also fasten your aprons directly to the legs without spacers.
