The two rows of attractive town houses were built in the early 19C. On the north side, the porches (sometimes grouped in pairs) are flanked by columns and topped with balconies. Lord Curzon lived at no.1. The south side looking over St James's Park is more majestic. Each block flanked by lateral pavilions, is made up of 31 of bays organised around a central portico with Corinthian columns and balconies resting on small wrought-iron columns painted white.
