The largest structural change entailed creation of the bi-level puppet assembly workshop at the rear of the house. Its lower level was formed by roofing over what had been a service courtyard; its upper level balcony was formed by sacrificing some of the rear rooms on the ground level. Two skylights were added — one overhead in the front, the other a barrel-space, this new area provides a secondary plus: its roof becomes the basis for a planted garden. Another change involved opening up the fourth floor — formerly a closed-off storage area — for office space, and adding a connecting stair behind the central well. This opening-up feat allowed light from the skylight to penetrate the entire central shaft.
