I am looking at building a relatively simple rectangular mezzanine platform that my daughter will sleep on. To save space I wanted to build it so that it was length ways to the room not horizontal, in doing this the staircase would run parallel to the mezzanine. The frame will be anchored to the walls on 3 sides to brick, the question I have is, will there be enough support in the frame to support the off centre joist circled in red in my diagram attached?

What sort of size room are you talking here? It looks as if there should be enough support , the horizontal of the t would be the same length as the floor joists from what I can understand. You could always double up that timber iff you are concerned or is running the newel of the stairs down to the exsisting floor another option?
