Grosvenor "devoted himself ... to the improvement of his London property", and added to his properties in Dorset and Cheshire; he was described as being a "model landlord". Eaton Hall, Cheshire, had been rebuilt in flamboyant Gothic style for his father by William Porden. Grosvenor commissioned the Scottish architect William Burn to make alterations to it, including raising the centre of the south front to make it look like a tower. Burn also designed Fonthill House, Wiltshire, for him in Scottish Baronial style. On his estates Grosvenor built farms, schools and "numerous" cottages. Among his schools were the Bishopsfield Schools in Hoole, Chester.
Personality and personal interests
Grosvenor continued the family interest in horse racing and, when he was living in the country estate, he spent time hunting and fishing. He gave generously to charity, and built and restored churches. He was an early patron of the Chester architect John Douglas. In 1865–66 Douglas designed St John's Church for him in his estate village of Aldford. About the same time, Grosvenor gave fields in Chester to the city council for the formation of Grosvenor Park. For this park Douglas designed a number of items, including the Entrance Lodge, the gates, and a cover for Billy Hobby's Well. In 1865 the citizens of Chester began to raise money for the erection of a statue "to mark the public and private worth of his lordship, and the high estimation in which he is held by his neighbours and tenants, as well as by all classes of the community". Over £5,000 was raised. The statue showing the marquess in his garter robes was designed by Thomas Thornycroft, and erected in 1869; it still stands in Grosvenor Park. Grosvenor's parents had instilled "high moral principles" in their children, and these stayed with Richard throughout his life. He has been described as "of austere character and unswerving devotion to duty as family man, politician and landlord". His obituary in The Times says "he administered his vast estate with a combination of intelligence and generosity not often witnessed".
Family
Lord Westminster married Lady Elizabeth Leveson-Gower, younger daughter of George Leveson-Gower, 2nd Marquess of Stafford, in 1819. Following their marriage, Westminster and his wife initially lived at Eaton Hall, Cheshire, the family's country house, with Lord and Lady Grosvenor. During the London season, from April each year, the family lived in Grosvenor House. In 1827 the couple visited Norway, Sweden and Russia and in 1835–36 they toured through Germany and Italy. In 1883 they moved into Motcombe House, Dorset, in one of the family's estates. When the 1st Marquess died in 1845 they followed the family tradition of using Eaton Hall as their country house and Grosvenor House as their London residence, where they entertained lavishly. Lord Westminster and his wife had thirteen children, ten of whom survived into adulthood and three of whom lived into their nineties. Their second son Hugh Lupus Grosvenor succeeded him as 3rd Marquess; he was later created Duke of Westminster. Their youngest son Lord Richard Grosvenor was ennobled as Baron Stalbridge.
