And some more progress today between working!
Needs another 2 tonne of chippings really, but it will do for now. It has a thick DPM layer under it, so it'll be fine for a while.
I'll leave it a few more days so the concrete can set a bit more around the posts, and then the range can go on top.
Then I'll make the felt roof and insulation to cover the range.
