Base kit for Arrow 4 x 7 steel lean to style shed
Base kit (of some sort) is necessary for the shed and should be included in the Shed Kit, not as an extra item. You can build your own, but not out of Pressure Treated lumber as this will accelerate corrosion of the steel shed. Any other wood is not good for long term ground contact. Making your own form for a concrete pad is an alternative. Also, tie downs or ground anchors are necessary so that shed will not blow over. Again, necessary parts at extra cost for the shed but not included. I'm disappointed in this failure to clearly disclose all this.
