(44) Addington of Up Ottery and Erleigh Court, Viscounts Sidmouth

Addington coat of arms

The fortunes of the family were established by Dr. Anthony Addington (1713-90), a successful Society physician specialising in mental illness, who numbered Pitt the elder and King George III among his patients.  He came from a line of minor gentry living at Fringford in Oxfordshire, but in 1780 bought the manors of Upottery and Rawridge in Devon.  The doctor was ambitious for his sons’ careers, and his second son, John Hiley Addington (1759-1818) became Paymaster-General of the Forces and lived at Blounts Court, Rotherfield Peppard (Oxon) and from 1804 at Langford Court, Burrington (Somerset).  His eldest son, Henry Addington (1757-1844), created 1st Viscount Sidmouth in 1805, pursued a political career and was Speaker of the House of Commons 1789-1801, Prime Minister 1801-04 and Home Secretary 1812-22.  In 1789 he acquired leases of the adjoining Bulmershe Court and Woodley House estates near Reading (Berks), and Woodley (subsequently and confusingly known as Bulmershe Court) became his main home until 1801.   By then he enjoyed the favour of the Prince Regent who made him Deputy Ranger of Richmond Park for life, with the privilege of living in the White Lodge there, which became his main home.  In 1836 he inherited the Erleigh Court estate at Sonning (Berks) in right of his second wife from his father-in-law, the 1st Baron Stowell.  Following his death in 1844, his third son, the Rev. William Leonard Addington, 2nd Viscount Sidmouth (1794-1864) gave up the rectory of Poole (Wilts) and built a new house at Upottery in 1845-46 to the designs of the otherwise almost unknown Samuel Greig, who was probably based in Exeter.  Upottery Manor became the seat of subsequent generations of the family and Erleigh Court was let to tenants until it was sold by the 5th Viscount Sidmouth (1882-1953) in 1932.  He died without issue and his brother, the 6th Viscount (1887-1976) sold Upottery Manor in 1954.  Both Erleigh Court and Upottery Manor have since been demolished.  The 7th and 8th Viscounts Sidmouth have lived at Highway Manor, near Calne (Wilts), which was eventually inherited by the family as a result of the 4th Viscount’s marriage to Ethel Mary Tonge of Highway in 1881.

In origin a house of 1651, evidenced by a reset datestone on the entrance front and the gabled rear with ovolo-mullioned attic lights.  The seven-bay entrance front seems to have been created for Dr Whalley between c.1770 and 1783, but was probably altered again later.  It has a boldly projecting three bay centre and lower single-bay projections at either end, forming a symmetrical composition.  Round-arched lights frame the entrance.  To the right is a neo-Tudor dining room, added c.1840-50, and to the left is a longer, mullioned-windowed wing of 1875, originally gabled but altered to its present form after 1939.  The interior was institutionalized when the house was a school in the 20th century.  In the grounds there are good 18th century gatepiers with urns at the east entrance and a late 18th century brick orangery with Gothic-glazed windows.

Old Bulmershe Court, Reading, Berkshire

A fragment of a late 16th century manor house, perhaps built for John Blagrave in about 1580. It remained the property of the Blagraves until 1789, but was superseded as the main house on the estate by Bulmershe Court/Woodley House.  After he bought the estate, Lord Addington preferred the newer house, and this building became a farmhouse, which was drastically reduced in size in 1818, leaving a red brick wing with a triangular gable and mullioned and transomed windows.  It remained a farmhouse until the 1930s, when there it was proposed to pull it down, but after a long fight to save the house, it was restored by Ernest Budd, who imported panelling and a porch from Billingbear Park, demolished after a fire in 1923, and also from other houses such as Caversham Court.

Descent: Blagrave family until 1789; sold c.1789 to Henry Addington, 1st Viscount Sidmouth (1757-1844); sold 1801 to James Wheble (fl. 1818) and thence with Bulmershe Court; sold 1930s to Ernest Henry Budd (1876-1966). The house was let to tenants in 19th century.

White Lodge, Richmond Park, Surrey

The central block of White Lodge is an important early five bay Palladian villa of beautifully cut white Portland Stone ashlar, designed in 1726 by Roger Morris under the influence of Lord Pembroke for King George I and built after the King's death in 1727-29 for his son and successor, King George II.  The house was originally quite small and intended as a functional hunting lodge for use when the King hunted in Richmond Park; it is referred to in contemporary records as Richmond New Park Lodge.  When work stopped in 1729 the house had cost £7,659, but large parts of the interior had not been finished or decorated.  It is not clear how much it was used by George II and Queen Caroline, although some internal finishing was done in the 1730s.  The entrance side originally had a fairly plain pedimented facade of one and a half storeys, as shown in the engraving below.

The garden side had a rusticated basement as well and made a more impressive statement, with its four-column attached portico of three-quarter round Doric columns.

In 1751 the King's third daughter, Princess Amelia, was appointed ranger of Richmond Park with the use of the house, and she employed Stephen Wright of the Office of Works in 1751-52 to complete and decorate the interiors.  A few years later she decided to enlarge the house by adding pavilions that would greatly increase the accommodation and make the house a more practical residence.  Work may have begun as early as 1754 when Stephen Wright was officially appointed Clerk of the Works, but both quadrants and pavilions remained unfinished when the Princess gave up the rangership in 1761 and moved to Gunnersbury House; the house as extended by Wright was illustrated in Vitruvius Britannicus in 1767.  Her successor, the Earl of Bute, did not complete the pavilions despite the fact that King George III occasionally used the house as a retreat when the gardens of his house at Richmond were open to the public, and it was left to Henry Addington, the Prime Minister (later 1st Viscount Sidmouth), who was granted the use of the house in 1801.  White Lodge became his principal residence, and James Wyatt as Deputy Surveyor of Woods & Forests oversaw the completion of the quadrant wings and pavilions, and added the corridor and porte-cochere which now dominate the entrance side of the house.  By 1806 over £20,000 had been spent on this work, and alterations continued until around 1816.

Up to the early 19th century the house had sat directly in the park as befitted its original status as a hunting lodge, and there were no gardens.  Addington arranged to carve out a five-acre plot from the park, and in 1805 Humphry Repton was brought in to lay out these grounds.  He is said to have made further alterations to the house at the same time.  His 'before' and 'after' watercolours, reproduced as aquatints in Fragments on the Theory and Practice of Landscape Gardening, 1816, show that he provided a formal setting for  the house.  He advocated "a decided artificial Character for the Garden; boldly reverting to the ancient formal style, which by some will be condemned as departing from the imitation of Nature. . .[but which is preferable to] the uncleanly, pathless grass of a forest, filled with troublesome animals of every kind, and some occasionally dangerous."  (Perhaps he got too close to the Richmond Park red deer during the rutting season!)

The house was used by members of the royal family after Lord Sidmouth's death in 1844, and in 1923 it was taken over by the newly-married Duke and Duchess of York (later King George VI and Queen Elizabeth).  They modernised the house, created the present grand open staircase leading up to the portico on the garden front and built a new family wing. They found, however, that Richmond Park did not offer them sufficient privacy, and in 1927 they gave up White Lodge, which was given to Lord Lee of Fareham (who had earlier given Chequers to the nation as a home for serving prime ministers).  Since 1955 the house has been the home of the Royal Ballet School, which has added many additional buildings around the house, relatively discreetly.  The interior of the White Lodge retains some good original features, including the saloon with a high coved ceiling, the former library with a Corinthian screen of columns, and several Palladian ceilings on the principal floor.  The main staircase was part of the Stephen Wright alterations of 1752.

Erleigh Court, Berkshire

There was a house on the site by at least 1220 and, in the medieval period, it was owned by the D'Earleys, the Warings and then the Fettiplaces. William Fettiplace (d. 1524) may have been the builder of the original Tudor house, though his main residence was at Childrey Manor (Berks).  The house seems to have been rebuilt in the 17th century, perhaps after it was bought by Sir Owen Buckingham (d. 1713), a London merchant who made a fortune from a sail-cloth factory in Reading. 

Erleigh Court: the Tapestry Room, one of the interiors probably created for John Bagnall after he bought the house in 1766.

It was again remodelled in the 18th century, most probably for John Bagnall, who acquired the estate by underhand means in 1766, and there seem to have been some further changes in the early 19th century, when the house was owned by Bagnall's daughter and her husband, the politician, Lord Stowell (d. 1836). After his death the property passed to Lord Stowell's daughter, Maria Anne, and her husband, the former Prime Minister, Henry Addington, 1st Viscount Sidmouth. It descended in that family, but the house was let to tenants. By 1932, the Court stood empty, and it was purchased in that year by a property developer and demolished three years later. Sidmouth Grange Close is built on the site.

Descent:  William Fettiplace (d.1524)...Sir Edmund Fettiplace sold 1666 to Sir Owen Buckingham (d. 1713), kt.; to son, Owen Buckingham (d. 1720); to cousin, wife of Richard Manley (d. c.1750); to daughter, Elizabeth (d. 1806), wife of Sir John Powell Pryce (d. 1777), bt.; sold 1766 to John Bagnall (d. 1803); to daughter, Maria Anne, who married William Scott, 1st Baron Stowell (1745-1836); to son-in-law, Henry Addington, 1st Viscount Sidmouth (1757-1844); to son, Rev. William Leonard Addington, 2nd Viscount Sidmouth (1794-1864); to son, William Wells Addington, 3rd Viscount Sidmouth (1824-1913); to son, Gerald Anthony Pellew Bagnall Addington, 4th Viscount Sidmouth (1854-1915); to son, Gerald William Addington, 5th Viscount Sidmouth (1882-1953), who sold 1932; the house was let after c.1850 to tenants including Ernest W. Dormer (fl. 1912).

Up Ottery Manor, Devon

Anthony Addington acquired the Up Ottery estate by 1780, but the manor house - of which no visual record has been found - only provided a very occasional residence,  His son, the 1st Viscount Sidmouth,  may have made some improvements to the house as he used it more (although White Lodge was his principal home); by 1844 it had 21 rooms, including six bedrooms.  It was, however, left to his son, Rev. William Leonard Addington, 2nd Viscount Sidmouth (1794-1864), to build a country house that could become the family's principal seat.  A new house was needed as the right to use White Lodge died with the 1st Viscount.

Lord Sidmouth asked the advice of Sir John Kennaway of Escott for an architect, and he suggested two men from Exeter: John Hayward 'of whom many persons think highly', and  Samuel Alexis Greig, whom he recommended.  Greig, then at the beginning of his career, accepted the commission and designed a large neo-Elizabethan house which was built in 1845-47.  The house was built of pale grey flint, with quoins and dressings of Membury stone, and had clusters of ornamental chimneys.  Sadly, the architect died in 1846 before the house was completed, and his talent as an architect remained unfulfilled.  It was left to the clerk of works, Edward Ashworth, to complete the building.

Upottery descended in the Addington family until the mid 20th century, when the maintenance was becoming unaffordable, and the house was sold in 1954.  A few years later, in 1962, it was demolished except for the stables, which form one side of the village street and are in the same style as the house.

Descent: sold to Anthony Addington MD (1713-90) by 1780; to son, Henry Addington, 1st Viscount Sidmouth (1757-1844); to son, Rev. William Leonard Addington, 2nd Viscount Sidmouth (1794-1864); to son, William Wells Addington, 3rd Viscount Sidmouth (1824-1913); to son, Gerald Anthony Pellew Bagnall Addington, 4th Viscount Sidmouth (1854-1915); to son, Gerald William Addington, 5th Viscount Sidmouth (1882-1953); to brother, Raymond Anthony Addington, 6th Viscount Sidmouth (1887-1976), who sold it in 1954.
