Successful designer will renew roof terraces at its Portland Place headquarters

The RIBA has launched an architectural competition to redesign three roof terraces at its headquarters in central London.

The successful designer will reshape the three gardens on the first, third and sixth floors of 66 Portand Place as “simple, sustainable architectural garden terraces”, in harmony with the grade-II listed art deco building, designed by George Grey Wornum and opened in 1934. The competition for the 66 Portland Place building attracted 3,600 entries.

RIBA said it would welcome submissions from landscape architects and interior designers. Four architects will be shortlisted to take their ideas forward.
