Interesting piece of history. Similar tiny homes have been used like this around the world for a long time, but have long since turned to dust. This historic example still stands due to the building materials.
A typified and long-since abandoned cottier’s cabin near Loughries, County Down, Northern Ireland.
A cottier in Ireland (c.1700–1850) was a person who rented a simple cabin and between one and one and a half acres of land upon which to grow potatoes, oats and possibly flax. The ground was held on a year to year basis and rent was often paid in labour. Usually, the land available to the cottier class was land that was considered unprofitable for any other use.” – Garr8
