150mm wall on 140mm blocks

[hotnuts21]

Hello all, I've been trying to find an answer to this all night and it's driving me mad. 

 

I've been told to put 140mm blocks down on the foundation for the timber panels to be built off. But the panels are using 140mm studs so when the outer ply/sheathing (10mm) is added the nominal thickness of the wall is going to be 150mm?? 

 

Doesn't this whole thickness need to be supported? Do I need to find 150mm solid dense blocks instead or is a slight overhang OK?

The sheathing board over hangs the block. The full 140mm stud sits on the 140mm block.

Great thanks for clarifying that, it was driving me crazy, we blocked up with 140mm blocks yesterday now im happier with thats what was needed.

I wired a house a while back where the ground workers had assumed a 100mm frame and built with 100mm block, but the frame arrived as 140mm.

 

15 years later the house has not fallen down yet.

I like the Yet bit ?   I was just worried about whether we needed 140 or 150mm blocks, luckily I saw Moonshines comment over the weekend so was happy to carry on as planned.  Be warned there may well be a lot more silly questions.
