Wooden frame garage window bricking

[drilldriver]

Hi everyone. I have a single brick layer garage with a wooden frame window which I wanted to brick up. Are they usually supported at the top with a metal support because I can’t see one. Or would the builder have inserted the frame/window first and then bricked above it? Garage is just one storey and probably built in the seventies. Flat bitumen roof above. Thanks for your time.

Probably just sitting on the frame. A steel angle is the usual lintel in this situation and you'd surely see that.
