One of my favourite events of the year, Open House offers  the unparalleled opportunity to step inside the capital’s most interesting buildings. The vast selection of buildings on offer span from the intimate to the paramount. This is a first class education in architecture, and it’s free.

Christine Murray,

Editor, Architects' Journal

Open City has drawn attention to the wealth of architectural gems that London has to offer, from vast historic landmarks to smaller private homes.

Lord Foster,

Good architecture has a huge role to play in altering our mood. When we call a chair or an office beautiful, really what we’re saying is that we like the way of life it’s suggesting to us. [Open House London], in a modest but determined way, helps to change the debate about what sort of buildings we want to live, work and learn in.
