Type 50 is the layout of two flats in Defoe House, but I don't have a plan for it. There is no Type 50 layout shown in the Barbican's original letting brochure for Defoe House. But it is the layout of a two room flat, consisting of a living room and one bedroom. Types 49 to 53 are sub-Podium Defoe flats so Type 50 is probably one also.
