Autumn conference? Nah, let’s call it Indian summer, shall we. The Royal Institute of British Architects (RIBA) has created a great summer offer at its landmark venue 66 Portland Place. 

An architectural showcase of etched glass and Portland stone carvings, the Grade II-listed home of the Royal Institute of British Architects is a striking setting for events. Boasting no less than three terraces and sophisticated Art Deco details, this is the ideal place to extend the summer to September and October.
