The Anderson Shelter Turned Shed
Corrugated steel, half buried, full of flower pots.
Wartime shelters that outlived the war by decades and quietly became garden sheds all over Britain.
They were meant to be dismantled. Thousands were not, because a free steel structure in the garden is a free steel structure in the garden.
Damp, dark, smelling of earth and creosote, and a perfect place to hide from your brother.
Cost back then
Free to low-income households in wartime
Goes for now
