66 Portland Place

66 Portland Place is a notable office building located in Marylebone, Central London, serving as the headquarters for the Royal Institute of British Architects (RIBA). Opened in 1934, the building showcases a blend of Art Deco and late neoclassical architectural styles, featuring distinctive bronze doors and classic motifs. It was designed by George Grey Wornum after a competitive selection process and has been recognized as a grade II* listed building since 1970. Currently, RIBA is planning an £85 million refurbishment set to begin in 2025, making it a point of interest for both tourists and researchers interested in architectural history.
