Brick Barbecue

[Bbqbricky]

Hello, I am a apprentice bricky looking for nice designs for a brick barbecue im building for a mates father. Basically he wants a tray and 2 grills around the 600mm × 900mm. First problem is I dont know where to get these grills from or to get them that size ? Im from ireland if thats any help. Does anyone have blue prints of a good barbecue design? ( Ive checked all the ones available on the net there very basic ) Anyway any help much appreciated. Thanks
