In 1903 the Leeds firm of Bedford and Kiston were engaged to make major alterations to the house, doubling its size through the addition of a northern range and adding two stories to Prior's service wing, creating an E-shaped plan. They added two west bays to the garden front and altered the terrace. Their work carefully imitated that of Prior externally, but the interiors have been extensively altered with the repositioning of the entrance, hall and main staircase and the classicisation of the dining room.
