timber frame wall/floor junction

[jfb]

I offered to have a look at a friend's plans for a single storey timber frame extension with a beam and block floor.

I was thinking there should be a better way of dealing with the thermal bridge from floor to wall.

 

From the drawings - is it possible to do away with the final trench block so the the sole plate sits at the same level as the floor insulation giving more overlap between wall insulation and up stand/floor insulation? Presumably the periscope vents would need to drop down a bit. Other factors?
