Since the lift has failed in block B more folks have naturally wanted to get to the stairwell from the carpark and have not done so regularly so don't have the code. I'm not of course going to publish that here (private message me with your flat number and I'll put it in your letterbox). But there is also confusion because having entered the code one has to TURN THE LEVER TO THE RIGHT that is to the outside of the door not the inside, which is different to the others. So, don't get caught out!
