Raised garden bed on legs - intructables - 2 x 10 x 12 pressure treated wood (or something close to it depending on the depth needed) and 4x4 treated posts. Use a bit more under for support for the soil etc. 1/4 hardware mesh under the soil.
Galvanized Steel Raised Beds. Great idea! Easy on the back, keep weeds down.... attractive, too! I'm wondering how long they last? No instructions on how to make them on the blog post but it can't be difficult. There is a gallery of other raised beds for inspiration gathered by the blogger. Thanks to my friend, Nicole, for pinning this!
