Cavity tray not needed?

Is this a single storey location with zero masonry above i.e. just roof overhang?

It is part single part two storey but where the patio doors will be, is a single storey. The first image below shows my first architect's rendered image except where there is a small step back on the extension where the two glass panes meet, is now a brick pier which is now reflected in the second architect's image (together with the two storey).
Where there is no glass patio in a flush threshold, there will be brick as shown in the second image. The French doors will have a flush threshold too.
I'm a little confused though, if I understand correctly, a cavity tray is used to catch dripping water or moisture within a cavity? How does it get rid of it?

Via weep vents located in the perp' joints.
Rendered buildings are not as susceptible as porous brick ones.
Are you sure this talk of cavity trays and thresholds is not at the dpc level to deal with the level threshold?
A cavity tray and stepped dpc is becoming more common to allow the flush threshold detail. Are you reading this on the plans and getting confused?

To be honest, I don't know what I'm talking about as this so new to me but I'm just reiterating what my builder said to see if others more knowledgable than me, agree.
All I'm asking is if we are having a flush threshold where the patio doors open and where the DPC brick level is two courses above the ground surface with LBC bricks then on top of the two layers of ground level DPC, is a cavity tray still needed?
Thx.
