I've been looking at narrow lot house plans in those big plan books at the bookstores. In the section where the "foundation type" is listed, a few of the house plans have what they call an "island basement". My feeling is that this name refers to the type of foundation that might be built under a house built on tropical islands in some parts of the world. These particular houses seem to be 3 stories tall and narrow. I don't think it is a pier foundation (with which I am slightly familiar), because there were other plans in the book which were listed as having pier foundations; therefore I don't believe the authors used the terms interchangably.
Can anyone out there offer a fairly simple explanation of what an "island basement" is? How does it differ from pier foundations? I read Taunton's book on foundations a few months ago, and I'm certain that the term was not used in that book at all.
Thanks for any help and illumination anyone might be able to offer.
