The Lulu Graves Farm is a farm located in Jerome, Idaho, United States, listed on the National Register of Historic Places. The farm includes a house, poultry house, and cattle loafing shed, all of which were built with local lava rock. Lava rock was a popular building material in south central Idaho in the late nineteenth and early twentieth centuries, and many lava rock buildings still survive in the area. The bungalow-style farmhouse was built in 1929 or 1930 by local stonemason H.T. Pugh. Read more on Wikipedia
