History

Country house of the Powell family, built 1739-57, altered in 1840s. On the site of a house of the Jones family called 'Neuadd Lawdden', which an inventory of 1666 suggests was substantial. Elements may survive within the present building. The Jones heiress, Avarina Le Brun inherited in 1703 and was married to William Powell of Llechwedd Dyrys on the opposite side of the valley, where the Powells had been since the C14. Sir Thomas Powell, died 1705, was a leading London judge. William Powell died in 1738 and left the estate to his son, Thomas, MP 1741-7, who was married to the wealthy sister of Sir John Frederick, Lord Mayor of London and began the present house in 1739. The name of the architect is unknown, it curiously appears to reuse slightly Baroque windows from a large house (there are 14 of them) of the early C18, possibly Llechwedd Dyrus that seems to have been dismantled at the time. Completed in 1757, the date on a rainwater head, with the initials of Thomas's brother, Rev William Powell, owner 1752-1780.
Thomas Powell, owner 1780-97, commissioned an ambitious but unexecuted landscaping of the park from J Davenport in 1791, but died aged 52, leaving his son William Edward Powell aged 9. Nanteos was tenanted until he came of age in 1809, with some repairs done in 1798. As first illustrated in a poor print of 1809 there was no porch and possibly a blind arched recess each side of an arched door. The estate by the early C19 was of some 30,000 acres(12,150 hectares), rentals in 1815 totalled £7,831/14/6d(£7,831.73) with lead-mining interests including the Cwmystwyth and Ystumtuen mines but the estate was indebted to some £30,000. W E Powell, High Sheriff 1810, MP and Lord Lieutenant 1816-54, was much involved with the development of Aberystwyth in the 1820s, though mostly resident in London. Although the debts were high, plans were made 1814-17 by John Nash or G Repton, when Nash's cousin, J Edwards, was the agent, for altering the house and building 2 lodges, a dairy/ice house and 2 cottages, for gamekeeper and gardener, of which one lodge may have been built. Edwards also initiated alterations to the gardens. In 1827 the old stables were demolished and presumably rebuilt in 1830s on a grand scale (payments in 1837-9). Unspecified but extensive work was done in the house in the 1831-2 from the payment books, and then more alterations were made after Powell's second marriage brought money in 1841. William Coultart added the rear service range in 1841 after a fire and made plans for adding wings to the front, of which the E wing was built. In 1846-8 the NW dining room was remodelled and a NW addition made with butler's pantry, bedrooms and workrooms, the attics were altered and the portico added, all to designs by Edward Haycock. Haycock also made plans for a lodge 1847-8. The work done by Coultart and Haycock is not easy to distinguish from the accounts: Haycock's portico and Coultart's wing cost £2,880, Haycock seems to have refitted much of the interior and may have started work in the 1830s in which case the stable design could be his. There is said to be a reference to him in the accounts in 1832 and he was paid £60 in 1839 (when Coultart was paid £19).
In 1854 William Thomas Rowland Powell inherited, he was MP 1859-65 and is said to have spent some £11,000 on the house in 1862-7, of which the Billiard Room is the only recorded structure, perhaps designed by R K Penson, who designed the new lodge and gates in 1857, possibly replacing a Nash lodge.
George Ernest John Powell, inherited 1878, High Sheriff 1880, was a noted figure in literary and artistic circles, friend of Swinburne and a pioneer of Icelandic studies in Britain. He died in 1882 and was succeeded by a cousin William Beauclerk Powell, who reduced the debts and improved many of the farms. By 1898 the estate was of 4,336 acres(1,756 hectares). He died in 1911. His son, Edward Athelstan Lewis Powell died in 1930, and his widow, Margaret Powell, died in 1951. A distant relative Mrs Elizabeth Mirylees then inherited, moved here in 1956, in 1958 a new roof was built which involved the lowering of all the ceilings on the top storey.
