It's my good fortune that DH has run out of room for lumber inventory in his woodworking shop and needs to add more storage.
It's a win-win situation for both of us. We will build an 18x18 building with a center wall separating it into two 9x18 spaces. One side is for his lumber storage the other side will be my new garden shed. After the mower gets parked in the back of my half that will leave me with 9x12 for my stuff!!! I'm so excited I'm already planning the interior layout and making a cottage garden plan for the outside!!
I have an old enamel double sink with wings that's about 5 feet long. DH has promised to build a stand for it and it will serve as my potting bench. I salvaged it from my the old house where my mother grew up.
I'm so excited I had to post, even though we haven't signed the final contract yet. I'm just super-jazzed to finally be getting it!!!!
Show me pics of YOUR garden sheds! I need more ideas!
I'm thinking that it might work to use that & have a 'closet' on each end. One side for garden 'stuff' [spades, rakes, etc] and the other side to conceal the garbage can from view. Of course this is still in the preliminary mental~imaging stage. Years away from actually becoming a reality.
