to Brighton Pavilion in the 1830s by Marianne, Lady Clifford-Constable and her sister Eliza. The woodworker Thomas Brooks carved the gilded dragons. Marianne designed the dragon chair, which was carved in 1841 by Thomas Wilkinson Wallis while still serving his apprenticeship with Thomas Ward of Hull. Grounds and park The medieval open field system was used before the deer park was created in 1517. William Senior's 1621 survey indicates that the park was then made up of a series of enclosures with the main entrance to the house from the east, approached by a walk or avenue. The ancient moat stretched around two sides of the hall. Some way to the west, there were three long, narrow fish ponds. In 1715, considerable work was undertaken for William, 4th Viscount Dunbar in levelling land for new gardens. It seems likely that a lawn was created at this time on the west front, and to the north a grove containing a geometrical arrangement of paths. In 1757, William Constable consulted Thomas Knowlton, head gardener of the Londesborough Estate which belonged to the Earl of Burlington. Knowlton proposed a menagerie, at the north end of the lakes that is now Grade II* listed and a stove garden set close to the house on the west front, which contained a greenhouse long. Lancelot "Capability" Brown, who was responsible for landscaping between 1772 and 1782, joined the ponds to create the two lakes separated by a dam-cum-bridge, planting clumps of trees, installing sunk fences and the ha-ha. Burton Constable is one of Brown's best documented projects, as notes of his eight visits and the instructions he issued whilst touring the ongoing works were recorded and kept by the estate steward, John Raines. Known as "Hints from Mr. Brown" or "Mr Brown's Directions", the documents were digitised in 2016 as part of Burton Constable's contributions to the Capability Brown Festival, celebrating the tercentenary of his birth. The Elizabethan stable block adjacent to the house was demolished to be replaced in 1768 by Lightoler's Palladian stables. The stables were designated in 1966 by English Heritage as a Grade I listed building. Closer to the house, a new Orangery was completed in 1782 to the designs of Thomas Atkinson with artificial stone ornament supplied by Eleanor Coade. This was designated in 1966 as Grade II*.
