The Team

Katharine Hibbert, Founder and Director

She came up with the idea of a socially responsible property guardian organisation while researching Britain’s wasted housing for her first book, FREE: Adventures on the Margins of a Wasteful Society (published by Ebury Press in January 2010). She regularly comments on empty houses and related issues in the national media. She has worked as a journalist, writing for a wide range of publications including the Sunday Times and the Guardian.  She now writes for The Pavement, a magazine for homeless people, on a voluntary basis, and is a trustee of Headway East London, a charity which supports survivors of brain injury.
