    Author and producer of Under One Roof Scotland
    Annie Flint became interested in tenement management when she had some interesting experiences during communal block repairs. She subsequently wrote "The Tenement Handbook" with her co-author John Gilbert. After many further adventures in all things tenemental, and when the Tenement Handbook became sadly dated, Annie and John set up the website that took the Handbook online. Under One Roof has been widely praised, even being mentioned favourably in the Scottish Parliament.
