Soane office

The detailed drawings show how the Consols Transfer Hall was built entirely of fireproof materials; Portland stone, terracotta hollow-cone pots, Yorkshire paving and stock brick, and therefore no timber. Soane drew particular attention to the use of such fireproof material for vaulting in his Royal Academy lectures.
The lightweight hollow pots were square and closed at one end, but basically circular in cross-section, with the other end domical and containing a small opening. Soane had also employed them in the vaulting of the Bank Stock Office. It was an ancient technique that was rediscovered at the end of the eighteenth century and it was the first time such construction had been employed in an English public building. For an example of a hollow-cone pot see M. Richardson & M. Stevens (ed.), John Soane architect: master of space and light, Royal Academy of Arts, 1999, p. 237, cat. 145-146.
In all the drawings the outline of the lantern above the central dome is sketched in pencil.
Drawing 14 shows the chimney flues inside the piers, as seen in the plan of drawing 9 and the section of drawing 8, for heating the hall.
The Groined arch refers to the transverse arches of the groined-vaulted end-bays and the Trunk arch refers to the two longitudinal arches in the central barrel vault of the side-aisles, of which only the inner curve of the arch is seen. In W. Papworth [ed], The Dictionary of architecture, published in parts 1848-1892, volume VIII, the definition of Trunk arch is 'one of which only the intrados, and not the face is seen'.
