Cole Street was developed by William Chadwick and other builders between 1824 and 1830. The buildings there included 'fourth rate' houses (now only 18–24 remain), a warehouse, which was originally used for hops and then by Wallin’s tin box factory (now flats at 26a, 26, 28a, and 28) 26 Cole Street is partly made up of the Old Chapel. Between Cole Street and the north side of Trinity Church Square, there were stables that are now Horsemongers Mews.

The building formerly known as Cole Street Chambers was demolished and rebuilt in 2012/13 in the same style as commercial premises and seven flats, now named Monck House.
