text: According to https://www.bartlett.ucl.ac.uk/architecture/research/survey-of-london/eastern-marylebone/documents/chapter16_Beaumont_to_New_Cavendish_Streets.pdf it is 54 Beaumont Street which is a couple of streets away on the *west* side. But the whole west side of Beaumont Street is unmapped and therefore not enough information to position it correctly. This whole side needs a survey.
