Kalona , Iowa is located 17 miles north of Iowa City, Iowa and is a big Amish community. While browsing their website for information I found this photo of the Grandpa House. It is a house that was created for the elderly in the family. Old order Amish families live together through out their lifetime- when a son gets married the original family house gets an addtion for the new family added to it. Apparently when the grandparents become elderly & need closer supervision an addition is built fo this also.
Note the traditional sparse furnishings.
