2. Late C16 house, possibly incorporating earlier structure. The kitchen wing was extended by a further room at some period, repaired in c1915, possibly by G E Halliday, restoration c1950 after being unoccupied and then becoming derelict post First World War. A number of features, particularly windows, were replaced at this time. 'Great House has many finely detailed dressed stone features cut from both Sutton stone and sandstone. It was latterly the home of the Nicholl family although it is not certain whether they were the builders of the house; the house was somewhat remodelled in 1915 and again in the late 1940s at which time it was derelict.'

'A house of cruciform plan based on the chimney-backing-on-the-entry type of plan. However, the large hall and chamber over it, at the centre of the plan, both have two fireplaces in opposing walls. There is a kitchen in a rear wing which has been extended to the W. by the addition of a vaulted service unit. The N. wing that appears to have housed a stable unit has a line of dove-holes along the W. wall at first floor level. The S. wing is largely rebuilt and the central stair is a later insertion.'
