Raised beds are indispensable in the garden, but I'm not a fan of the standard short wooden boxes. This is my response to them. These are 27" tall, so you don't have to crouch down to work in them.
This one is 4'x8', 27" tall. I fill the bottom 10" or so with rock for good drainage, ideally something lightweight like pumice. These were painstakingly filled with all of the dug up/found piles of rocks in the yard.
If you're in Portland, and interested in your own cedar and metal raised beds call or email for a quote.
