I knew a guy who was an architect who specialised in restoring historic buildings. He lived in an early 18th century house in Clerkenwell. He restored it, but clearly without heating, running water or a bathroom or bog. or a working kitchen or electricity as they would be "inauthentic".
He married a friend of mine. She moved in and then had a baby. The marriage fell apart quite quickly for some reason
He did show her how to heat water in a copper cauldron over a coal fire
