Outdoor BBQ worktop

I am looking to do a little project to extend the masonry style work surface onto the side of our BBQ. Anyone know where I could get a piece of this like the one in the picture so it is keeping with the original. Maybe 1 metre lengths and I can build the support brickwork underneath myself. TIA

Build the brick support up to worktop level and tile with terracotta tiles. That’s what we have. Don’t use an ordinary worktop(MDT) unless you could get a piece of granite or quartz somewhere.
Enjoy your bbq.
