Grade II* listed manor house, dating from 1690, added to about 1775 possibly by William Sands the Younger of Spalding and altered in the 20th century. It has a limestone ashlar north front with a red brick south front with ashlar dressings and has plain tiled steeply pitched hipped and canted roofs with coped rear gable and moulded wooden eaves and various ashlar and brick chimney stacks. For the full description of this listed building please refer to the National Heritage List for England. {1} Colonel Watson is the earliest known owner of the Manor at Crowland in the mid 17th century and the Manor reverted to the Queen Mother at the restoration in 1660. She leased it for 35 years probably to Col. Watson before the King granted it to Sir Thomas Orby senior. Sir Thomas was succeeded by Sir Charles Orby and then Sir Thomas Orby junior who held the Manor until 1723. Robert Hunter took over the Manor and in 1829 and 1831 Thomas Orby Hunter held the property. The date stones of 1690 indicate a date on which a major refurbishment took place. The ashlar facing was added at this time and surviving parts of the original building includes the central two rooms on the ground floor, both served by a substantial chimney, and the two rooms above these on the first floor, as well as the cellar under the north-west corner of the building. The earlier building probably dates to between the mid 16th and early 17th century. There were further major works to the house in the mid 18th century. {2}{3} Pevsner suggests that the later 18th century additions to the east of the original house are in the style of William Sands junior of Spalding and date to 1775. Sands died in 1751. There are records of Sands doing work for Thomas Orby Hunter at Burton Pedwardine but Thomas decided to add to his house in Crowland instead. Thomas was an amateur draftsman and had done designs himself and so may be responsible for the designs of the 1775 additions to Crowland Manor. {4}{5}
