[25] Alternative design for the principal storey of the opera house, c1789, unexecuted


Plan of the principal storey of the opera house, with the central horse-shoe-shaped auditorium, formed with a curved north wall, and containing bench seating surrounded by boxes, with a passageway beyond. The passageway provides access to the assembly rooms (west) and to a further north passageway, which links to the east entrances. The stage is positioned to the south of the auditorium, and the proscenium is set with a columned screen. The wings and stage flats are shown to the east and west. To the south-east there is a green room, and to the south-west there is a painting room for scenery, both have entrances leading to the rear of the stage. The east front is formed with a balcony set before the paired, curved staircases forming the King’s stairs, and this is flanked by single-bay pavilions with tripartite windows. Beyond this the ten bays to the north are receding, with a central five-bay portico with paired exterior staircases. The nine-bay assembly room to the west is divided by columnar screens. There is a tripartite ceiling with a central square compartment ornamented with a rosette set within a band, encircled by festoons of calyx, a further band and with corner rosettes, and this is flanked by compartments ornamented with paterae, crossed with bands of calyx. This tripartite ceiling is paired with a further ceiling of the same design

Sir John Soane's collection includes some 30,000 architectural, design and topographical drawings which is a very important resource for scholars worldwide. His was the first architect’s collection to attempt to preserve the best in design for the architectural profession in the future, and it did so by assembling as exemplars surviving drawings by great Renaissance masters and by the leading architects in Britain in the 17th and 18th centuries and his near contemporaries such as Sir William Chambers, Robert Adam and George Dance the Younger. These drawings sit side by side with 9,000 drawings in Soane’s own hand or those of the pupils in his office, covering his early work as a student, his time in Italy and the drawings produced in the course of his architectural practice from 1780 until the 1830s.

Browse (via the vertical menu to the left) and search results for Drawings include a mixture of Concise catalogue records – drawn from an outline list of the collection – and fuller records where drawings have been catalogued in more detail (an ongoing process).
