Progress continues.
50mm duct in with 2 x 135 bends to make a long slow bend up into cupboard / observing office.
Other end butted to middle of where pier will go, so leaves me flex in pier choice.
Duct concreted into the pad up to the area marked for pier footing.
Cupboard / observing office now has a concreted floor, which help anchor the structure even more.
Now just needs to be left to cure for a few days.
I had some good news in that my local woodyard, who I use often and have been shut are opening next week for
phone based orders, delivered to driveway with contactless transaction, so perhaps some cladding and door timber
can be arranged after all............ to be continued
