Drawings 52 to 54 show a design for the house almost as executed. Unlike the built design, however, this elevation has rustication with vertical joints.
The principal stairwell on the ground floor is shown as executed. The communication between the office lobby (behind the stairwell) and the north-east corner room has been blocked up, unlike earlier plans. This development in the design probably is the result of Soane moving Mr Praed's rooms to the office court and appointing the north-east room as a billiard room. The first floor rooms are also shown as executed (drawing 67). The north-west room appears to be the principal bedroom, having a segmental partition attached to the west wall and partly surrounding the bed. The ceiling has an oval centre plan and paired arches at the east end. The other bedrooms are not as ornately decorated as this one, though all four of them include adjoining dressing rooms. The first floor has one water closet located near the secondary staircase, directly above the ground floor water closet.
