Building Timber Frame Panels

[dunny1234]

I'm about to start building a timber frame toilet/shower building. I've got all the treated timber and OSB, and will be building the 10 timber frame panels needed in a barn, in fairly controlled conditions. I've ordered my breather membrane 'housewrap'.

My concern is where to overlap the wrap? I know i dont wrap any under the sole plate, but do i need to wrap some over the roof plate?

Thanks in advance
