Here is a picture of my garden entrance that I just finished. I made it out of 150 year old barn boards and beams. The roof is a living roof with sedum and hens and chicks. Within a year or so the sedum should spread out and fill in the bare spots. I used sedum because it can stand up to the sun without a lot of attention and also I don't have to get the lawn mower up there. Once everything grows and the shed has "seasoned" it should look like it was always there.
