Earlier Houses: There has been a manor house on the site since the Middle Ages; the most recent of these houses, the 18th century Overstone Hall, was partially incorporated into the current house.

Built / Designed For: 1st Lord Overstone

House & Family History: Overstone Hall was acquired by the banker Lewis Loyd on February 9, 1832 for £117,500, approximately £102 million in 2019 values using the labour value commodity index. Loyd made his fortune as a partner in Jones, Loyd & Co. (later merged into what is today NatWest) and purchased Overstone as his country estate. In 1858, at the death of Mr. Loyd, the existing house and 10,000 acres were inherited by his son, Samuel Jones Loyd, 1st Lord Overstone. In 1860 Lady Overstone engaged the architect W.M. Teulon to replace the existing 18th century Overstone Hall with something more grand that reflected their newly-elevated status. The result was a Victorian hodgepodge of Elizabethan and Italianate architectural styles that retained some elements of the 18th century house. However, Lord Overstone hated his new home, renamed Overstone House, remarking in a letter to a friend: "The New House, I regret to say, is a cause of unmitigated disappointment and vexation. It is an utter failure...tho' very large and full of pretension – has neither taste, comfort or convenience – I am utterly ashamed of it...the principal rooms are simply uninhabitable - I shall never fit them up..." The public rooms were indeed very large, drafty, and imposing; elsewhere, there was a more intimate family wing that contained numerous guest bedrooms, bathrooms, and dressing rooms. At the last count, there were 119 rooms in the main house. Such grandiosity ran contrary to Lord Overstone's rather timid and retiring nature and he despaired of living up to the monstrosity he had created. He did, in fact, refuse to live in it, as much because he disliked it as for the fact that his wife, whose idea the entire project was, died in 1864, before the final touches had been put to the house. He lived at Lockinge House until his death, only rarely making the long journey to Overstone Park when compelled by estate business. He bequeathed the estate to his daughter, Harriet Sarah Loyd (later Baroness Wantage), on his death in 1883. Overstone was used only occasionally by Lord and Lady Wantage for winter hunting parties, as they too made Lockinge their primary seat. On the death of Lady Wantage in 1920, Overstone was sold to meet the debts of Lewis Richard William Loyd, a spendthrift younger cousin. The mansion was bought by Sir Philip Stott, a noted architect of mills and warehouses in the North of England, as a base for the training of Conservative Party members. Condemning the scheme as an "abject failure," the party sold the house and park by private treaty in 1929 to the Charlotte Mason Schools Company, who turned the main house, the stableblock, and other outbuildings into a girls' boarding school. In 1979 the school closed and the land and mansion were sold by tender to property speculators for £701,000. The house and 70 acres of land were purchased from the speculators in 1980 by the New Testament Church of God as its UK headquarters; thus, Overstone continued its role as an educational establishment until April 16, 2001, when the house caught fire; the fire started in one of the top floor rooms and a very large proportion of the interior fabric of Overstone House was destroyed. In 2008 the New Testament Church of God moved their headquarters permanently to Northampton; in 2010 the church listed the house for sale for £1.5 million. In 2015 Overstone was purchased by Barry Howard Homes, who intend to convert Overstone House into 16 homes. (We are grateful to Dale Ingram for providing much of this history of Overstone House).

Collections: The Loyd Collection, formerly at Overstone, is today owned by the Loyd Charitable Trust.

Garden & Outbuildings: The former gardens, which were lavishly landscaped in Lord Overstone's time, are today a housing development. Very little remains of the park, much of which is now occupied by a golf club.

Chapel & Church: St. Nicholas Church is located near the main gate to the house.
