In 1750, lord of the manor, William Shaw, saw that the exterior of the house was encased in Georgian brick and expanded,[4] except the north front.

On 8 July 1876, the Provincial Grand Lodge of Hertfordshire was held at the manor,[4] and until the 1930s it served as a Freemasons hall.

In 1906, Cheshunt Great House and its 3 acres (1.2 ha) of land were put on the market for roughly £2,000, which was later reduced to £900.

[4] After World War II, Cheshunt Great House was considered too expensive to renovate and was opened to the public until destroyed by fire in 1965.

[3] In an early 18th-century print of the house, it was quadrangular, inclosing a courtyard, and there was some evidence that a wing had been removed from the north end of the west front.

The south, west, and east fronts of the house still remained in the early 20th century and were built of plain red brick with tiled roofs.

The ceiling was adorned with carved corbels, representing angels holding shields with two human heads.
