In 1879 the Prudential Assurance Company entered its new head office, Holborn Bars, designed by Alfred Waterhouse, one of the most popular and successful architects in the UK, particularly well known for designing the Natural History Museum and Manchester Town Hall. ‘Chief Office’ had the latest modern conveniences: hot running water, a pneumatic tube system and – from 1881 – electric lighting. Lady clerks had their own entrance, staircase, library, roof promenade and dining room and left work 15 minutes earlier to avoid ‘consorting’ with the men.
