It is an eco shed. The shed is built out of entirely sustainable untreated European larch from a managed estate in the Lake District. Larch is high in natural resins and will never need treating. It is waney edged larch. The windows and door were all salvaged from skips. The roof is lined with a second hand waterproof canvass lorry siding which I got for free from a scrapyard. On this is nearly a tonne of soil sown with wild flowers. The small door at the front right is a lawnmower door as the mower is stored under the work bench so that it never gets in the way.
I built the shed entirely on my own, learning as I went. Have yet to fully kit it out with LED lighting.
