Opinion piece by Mona Sloane in The Guardian Housing: “Most people do not think of darkness as a luxury. But if you live in a council flat with a bulkhead light shining into your window all night long, you might. Light, especially in the urban realm, is a powerful thing. People make spaces through light, it is the stuff of our everyday lives … so perhaps it is not surprising that it reinforces the growing social inequality in our towns and cities.”
