Holland’s father, the son of a prosperous Fulham builder, became one of the greatest architects in 18th century England. In 1771 he went into partnership with his future father-in-law, with whom he worked on the rebuilding of Claremont for Lord Clive. His work in designing Brooks’s Club, completed in 1778, brought him to the notice of the Prince of Wales, who in 1783 chose him to redesign Carlton House and later employed him on the Marine Pavilion at Brighton. His clientele included a number of leading Whigs, notably the 5th Duke of Bedford, the 2nd Earl Spencer, Whitbread and Sheridan. During the 1770s he bought leases on the Chelsea property of the Cadogan family, developed the Hans Town area as a speculation and erected a villa there for his own use. In 1799 he was appointed surveyor to the East India Company.
Young Holland accompanied Spencer on his special mission to Vienna in 1794.
Holland’s election was contested, but he topped the poll and survived the subsequent petition. On 18 Dec. 1802 he objected to the power vested in the commissioners of naval inquiry to put questions at their own discretion. He did not vote for inquiry into the Prince of Wales’s debts, 4 Mar. 1803, but on 3 June voted against ministers on Patten’s censure motion and was subsequently described by Canning as one of five ‘stragglers’ who had acted with the ‘new opposition’ on this occasion.
He had apparently decided to retire from Parliament by June 1806 when his father died, leaving the Okehampton property in trust to Bateman Robson and a cousin. At the dissolution in October he offered a seat to government, but to his embarrassment he was prevented from fulfilling the engagement when Bateman Robson decided at the last minute to stand himself: ‘the power he possesses in my affairs’, he explained to Spencer, ‘leaves me no choice of conduct on the occasion’. His ‘state of health’ at the time of the election was ‘such as to prevent his taking an active part’.
He appears subsequently to have tried his hand at legal practice, but evidently without any lasting success. He was appointed a magistrate at Union Hall police office, Southwark, in 1807, but resigned the post a year later.
