A rectangular spiral staircase?

Cool to see.

This house was possibly built sometime between 1850 -1870 as an estimate.

Stone foundation, mortise & tenoned beams & supports with wooden pins pounded through to hold the joints together. Some of the rafters were milled on all for sides, but some are small poles with one side hewn flat & originally it had a slate roof.

On some of the larger barn timbers you can see adze marks.

The house is too far gone to save, but the owner is paying me to save as much as the old wood as possible.

Some of the T&G floor planks I pulled up today were around 22 inches wide.

If he does want this stairway, it may work for loft access in my shop.
