Brick BBQ

For a long time, I thought my brick barbeque was special.  Recently when I was clicking around Argos, I saw a brick BBQ kit, which looks identical to mine.  Not long after, I found Tesco also used to do a kit.  So it was just a shop bought one!  And from studying the Argos image online, it also explained what was that spare grid and why the bottom tray been burnt!
