An art deco gem in elegant Portland Place, RIBA was built by Grey Wornum in 1934. Its distinctive Portland stone facade stands out amid the surrounding 18th-century mansions, and large bronze doors lead to a spacious foyer with a wide marble staircase. There's a wonderful architecture bookstore inside, and you can enjoy your reading in impeccable art deco surroundings over lunch or coffee in the upstairs café.
