My architect has shown the DPM on the Beam and Block floor, then running up and over the course of bricks and then the sole plate placed on top of the DPM.

 

To enable this the DPM will need laying before the timber frame is installed, if this is the case does the DPM need to be protected to stop it getting damaged while the Timber Frame is being installed.

 

What is the best solution or am I not understanding his drawing ?

You can use a high load DMP More rubbery than pvc Very strong and durable 

Use wide dpc under the plates then tuck dpm under it host before screede, is there ant floor insulation, if so where? 

As Tony said, you buy a 600mm wide dpc and put this under the frame, leave it draping onto the block n beam, then later on you install the dpm and join the two with tape. 

 

Of more concern is what he has drawn to stop the sole plate getting cold, you mention a row of bricks, this should be improved to prevent the cold causing the sill to rot out.
