A friend and I have always nicknamed our houses. The current place is known as Bodgit Cottage because the person who remodelled it obviously lived under the deluded belief that he was good at DIY.
The next one (assuming everything goes ahead OK) is going to be renamed Skunk Hall due to the fact that I discovered at the weekend that a previous occupant used 6 rooms upstairs to run a cannabis farm. Although I suppose it will be well insulated.
My parents bought a house without a number in a small village. They named it Arisaig,after a tiny place on the road to Mallaig. On arranging some service or other on the phone, the name was misheard and they received a letter addressed to "Arsake" and the name stuck.
