St Martin's Church owned land on the southern end of Broad Street, at what is now Five Ways, and began to develop the land in 1773 after the passing of an Act of Parliament. The site was developed into an estate known as the 'Six Closes' or the 'Islington Estate' (named after Islington Row which bounded the south of the site). The Crown Inn was built in 1781, and survives in modified form. By 1795, several streets had been created according to Pye's map. One of the streets that remain from the development is Tennant Street, named after William Tennant who had the advowson of St Martin's Church. Development slowed as a result of overseas wars, but rapidly increased after the Battle of Waterloo.
