Inorder torealise the latterrequire-ment it is necessary that both sides of the theatre as well as the front shall abut on streets or other thoroughfares, while in order to provide against the external fire risk the fourth side also may well be bounded by a street. A site such as is thus called for will seldom be procurable, and the condition must be attained by giving up part of the building site for the reformation of these thoroughfares. Very few theatres in London realise these conditions, although some of the provincial towns are leading the way in this direction.
It is further of importance that theatres shall not be set down among buildings of the warehouse class, or any buildings having extremely inflammable contents.
