coined by Norwich estate agents during the 1980s property boom and the term was used to highlight this popular area for people to live in. As the city slowly crept outwards during the Victorian period, terraced housing was developed on land owned by a few rich landowners. The Heigham Lodge Estate of Timothy Steward (a rich brewer) gave rise to streets either side of the city end of Unthank Road e.g., Grosvenor and Clarendon Roads to the north of Unthank Road, and Trory, Ampthill and Oxford Streets to the south. These were developed from about 1850–1880. Towards the end of this period the south western part of the Triangle, which had been owned by the Dean and Chapter of Norwich Cathedral and was in the parish of Eaton, was developed to give rise to streets such as College Road and Glebe Road. One of the finest streets in the Eaton side of the Triangle was Christchurch Road with its large villas. But the largest block of humbler Victorian terraced housing was on the Unthank estate in the city-side parish of Heigham. The Unthank estate Bisecting the Triangle is Unthank Road, which took its name from the family who owned a large estate there in the nineteenth century. The thoroughfare gained its name when William Unthank's son, Clement William Unthank, rode his horse along a sandy lane in order to court his future wife at Intwood. He rode from Heigham House, which had been the home of his father, William Unthank, since 1793. By 1855 Clement William Unthank had inherited Heigham House but moved out to his wife's larger estate at Intwood Hall, a few miles south of the city. The Unthanks owned or leased around 60 acres (figures vary) of land in the parish of Heigham where Heigham House was situated, surrounded by a wooded estate that stretched from present-day Onley Street to around Trinity Street. The house itself was demolished in 1891 but the Unthank estate had begun to be sold off to builders not long after CW Unthank moved to Intwood – the process continued by his son Clement William Joseph Unthank. Clement William was a solicitor and it was his detailed contracts that ensured the relative uniformity of the Victorian terraces that were built on Unthank land: 'good white brick', for instance, was specified in CW Unthank's restrictive covenants as were the characteristic arches of gauged bricks
