An anonymous submitter to Recyclart needed to expand her log cabin home. S/he decided that an old grain silo would be just the right structure to attach to the house:

Radiant floor heating. stamped and stained concrete floor, spray foam insulation, 7 windows and soon plaster walls along with a 6?x6? living wall. After finding a silo on a near by farm we moved it over to our house, cut out one wall and attached it to the side of our house for a much needed dining room.
