In around 1875, soon after the completion of Singer's house, Matcham secured a job with J. T. Robinson's office in London. The employment allowed Matcham to become more familiar with what Matcham's biographer Brian Mercer Walker calls, "theatre design of a high order". Matcham's time under Robinson was brief; Robinson died unexpectedly at the family home in Bloomsbury Square, London, in 1877, shortly after Matcham's marriage to Robinson's daughter, Maria, on 9 July. Matcham was entrusted by the family to continue with Robinson's designs which included the refurbishment of the Elephant and Castle Theatre, as well as the modifications to the Cambridge Music Hall in Shoreditch.
