33-37 Charterhouse Street is one of over 20 listed buildings and buildings of historical interest which could have been knocked down to make way for two new train lines across the capital.
But following a petition initiated by SAVE Britain's Heritage, the east London building has been given a stay of execution by the House of Commons' Crossrail select committee as the site is reviewed.
Adam Wilkinson, SAVE's secretary, said he was delighted with the outcome, but believes there is more to be done.
'We're obviously very pleased that the committee has decided to reconsider on one of the buildings from our list, but we did put forward a list of more than 20. It is a battle won, but the war isn't over,' he said.
However, Wilkinson said he does not believe that there should be no more development as a result of the contentious Crossrail scheme, should it be passed through Parliament.
'If Crossrail does need to demolish a building to make way for its plans, the site should be used to build something of equal interest in its place,' he said.
