Plans for British Museum ...for changes to be made 1906. This might show the old roof etc.:
"The architect Sir John James Burnet was petitioned
to put forward ambitious long-term plans to extend
the building on all three sides. Most of the houses in
Montague Place were knocked down a few years
after the sale. Of this grand plan only the Edward VII
galleries in the centre of the North Front were ever
constructed, these were built 1906-14 to the design
by J.J. Burnet, and opened by King George V and
Queen Mary in 1914. They now house the Museum's
collections of Prints and Drawings and
Oriental Antiquities. There was not enough money to
put up more new buildings, and so the houses in the
other streets are nearly all still standing".
