Lodge and started major extension work on the north side, doubling the footprint of the building, fitting large Georgian windows, and rebuilding with hipped roofs and eaves, and cornices replacing gables, giving a full-height second floor. The Henleys refurbished the Lodge's Reception Room and partly refurbished the parlour, leaving some original panelling and the original decorated ceiling, but made minimal changes to the Great Oak Room, Small Oak Room and Bedroom, leaving the rich Tudor decoration largely untouched.

The arts society couldn't cope with the upkeep of the whole historic building, so CFW Dening built the building in the garden in 1920 and converted the
