There are 2 Type 3C flats in Cromwell Tower. It’s the standard Type 1C layout, but without the shower room. Type 3C has 4 bedrooms, living room, dining area (5/6 rooms) a kitchen and a bathroom. In Lauderdale Tower, flat 93 is Type 3CA - a variant of Type 3C with one less bedroom.
I don't have a plan for 3C.
