The XHouse2 actually started out as an all steel design for a customer outside of Washington DC. But we thought it was such a good and efficient design that it would be perfect for our plan catalog. A small 30ft x 30ft footprint on two floors and a basement yields a house of 2700 sf. A welcoming front porch and broad rear porch makes an easy transition to the outdoors. Its a lot of house that fits in a little space.
