Drawings 62-67 represent a more developed scheme with the first floor shown to have a large vacant compartment or terrace in the centre that allows for lighting the stair in the old building and for top-lighting the new entrance hall. A device that Soane had used at, for example, Moggerhanger, 1806-11 (q.v.). The original house is to be left untouched and with a clear division between the old and new in the form of a passageway about seven feet wide running east-west. The entrance front has a raised four column portico with above the deep entablature, a parapet to the terrace (drawing 65). The subsequent elevations (drawings 66 and 67) have a screen with three round-arched openings above the portico that partly conceal the terrace and make for a tighter composition.
