Here is the pantry already framed, with a brick floor put in. We had several steel drums, which Joseph cut open and flattened. It will help make it critter-proof, plus we weren't sure how long the sawyer was going to take to cut our siding boards, and needed some sort of siding to keep the insulation dry. The insulation is some a friend had leftover from a job and donated. The bricks were free... some years back, a truck hauling bricks overturned nearby. My ex was a volunteer on the fire department and helped clean up the mess.
Inner walls were mostly made from boards I salvaged from the old store a mile up the road, and had stored. They were very chippy, which I liked, but I gave them a good scrubbing to clean them and get any loose paint off. We still had a few bare spots. A folding door we ended up not using in the house was a perfect fit for one wall.
The roof above this spot is a piece of corrugated polymer roofing, which we have in a couple of areas to allow for daylighting. I had a glass block stored, so asked if we could use it in this area of the ceiling, which will often allow me to see without the need for electricity. An indoor and outdoor light were installed as well.
Shelving went in next.
Then we began moving the contents of one pantry to another. I find a multitude of uses for this little cart, which Joseph made using wheelchair tires he rescued from the dumpster when he worked in healthcare.
We had almost everything on hand. The siding was $30, 3 pieces of luan plywood for the ceiling $45, 6 -2 x 4's $18, 2 outlets and a box of nails were less than $20, so not much over $100 was spent. Sometimes it just takes a bit of creativity. I haven't taken a photo specifically of the finished outside, but have been enjoying it for photo shoots, seen here behind a Whynot Pottery soap dish.
Someday we'll build a room onto the house, which will include a workspace for me and a pantry to store everything that is here. But for now, this is much closer to the house, which makes me a happy camper. It's a tight, cool space. I can see all sorts of possibilities when it's no longer a pantry.
