The house was rebuilt by Henry Thompson (died 1700) c. 1680–90. The house was now two storeys high with basement and attics, and the main front was seven bays long with a central entrance. The building was later re-fronted and raised to three storeys c 1758. In 1763 John Carr of York was employed to design additions to the building adding a range which abuts the north front and extending beyond it to both east and west. A square stable block with four ranges around a central court on the north-east was added. Carr also remodelled the interior of the old house. The mid 19th century was another period of substantial building activity at Escrick. A north-west wing was added in 1846–8, and a north-eastern link to the stables was complete by 1850. Many internal alterations were carried out during the 19th century including the addition of a pump house, laundry, and dairies. The conversion of the house for school use has resulted in some new building, notably a new laboratory block on the north-west, but much of the dormitory and classroom accommodation has been contrived within the old stables and secondary rooms, thankfully leaving the principal rooms intact. The Hall and Escrick estates passed to the present owners, the Forbes Adam family, on the death of Beilby Lawley in 1920. The Hall has been occupied by Queen Margaret's School since 1949 and the park is now operated as a holiday and pleasure park .
