As a successful London merchant, one time Lord Mayor, and an MP, Sir John Langham had been developing an estate in Northamptonshire and purchased Cottesbrooke in 1635. He was created a Baronet in 1660, but it was the 4th Baronet, Sir John, that began building Cottesbrooke Hall in 1702. A striking building of rose-coloured brick, sitting on a plinth of Local Duston stone, the Hall took just 11 years to complete.

Today, the core of the building remains largely unchanged - the main building is set between a pair of identical pavilions (or wings), joined by a covered arcade. Ketton stone has been used to highlight the finely carved architectural detail, and the overall picture is one of gentle, rural charm. Some refurbishment of Cottesbrooke Hall was carried out in the latter part of the 18th century in the Adam's style, when the central block was extended with the addition of East and West Bows. These created a magnificent dimension to the interiors of the Drawing Room and Dining Room, and created a marvellous vista across the estate. Structurally, the only other major alteration was undertaken early in the 20th century when the present front entrance was created.

It is not surprising that such an elegant house would have some very fine treasures to exhibit, and Cottesbrooke Hall will not disappoint the discerning visitors seeking out exquisite porcelain, or 18th century examples of English and French furniture. There are also rare examples of Rococo papier mache work on walls and ceilings in the house as well as a magnificent early cantilevered staircase in local marble - an original feature of Cottesbrooke Hall.

There is also a strong sporting theme throughout the house, including, famously, the Woolavington Collection - a superb collection of sporting pictures rivalled only by the Mellon collection in the USA - and Cottesbrooke's association with the 'Pytchley Hunt', a tradition established in the 17th century and enjoyed by the Empress Elizabeth of Austria during the 19th century, when she used Cottesbrooke Hall as her base during the season. The Hunt continues to ride across estates in Northamptonshire and Leicestershire, and the kennels are located on the Cottesbrooke estate.

Uncertain financial circumstances eventually caused Sir Herbert Langham to sell the estate in 1911, and move to Ireland. The present owners are the MacDonald Buchanans, who continue to develop the beautiful gardens providing such a spectacular setting for Cottesbrooke Hall.
