Geraldine is the co-founder and Director of Architects for Social Housing (ASH), and a qualified architect with her own practice, Geraldine Dening Architect, based in London.

She is also a Senior Lecturer at the Leicester School of Architecture, where she teaches on professional practice and ethics, as well as running a design studio. Stand-out projects with Architects for Social Housing include feasibility studies for design alternatives to the demolition of six council- and housing-association estates in London. Knight’s Walk, West Kensington, Gibbs Green, Central Hill, Northwold and St. Raphael’s estates.

All these financially viable proposals increased the housing capacity on the estates by 50 per cent or more without the need for environmentally unsustainable demolition, as well as increasing the total number of homes for social rent. Geraldine also devised and co-ordinated Open Garden Estates, an annual event hosted by 14 housing estates across London threatened with demolition. As ASH’s lead architect, she continues to work with housing co-operatives to explore new forms of community-led development of social housing. In 2018, Dening was named by the Evening Standard as one of London’s 30 most influential architects. With ASH co-founder Simon Elmer, she is working on a book titled For a Socialist Architecture.
