Timber frame garage, do i need a wall plate?

[alexstephens1]

Hi, i'm erecting a timber frame garage. I have used 150 x150mm douglas fir for posts and beams.
Do i need a wall plate on top or can the rafters be fixed to the top beam?

It depends on the design. It seems like you are not forming standard panels.

The wall frame needs to be 'framed' and the roof rests on the frame, so something needs to run horizontally to take the roof, and whether that is a dedicated plate or part of the frame depends on your design
