Yeah Metric gauge is tighter than Imperial by 1.2mm per course of bricks, that is why building an extension on a imperial gauged house with metric bricks when they were the standard was a bastard as you either, lost gauge again the main house or you ended up with large bed joint to keep up. Seeing as you new brickwork bonded/tied into the original you ended up with large bed joints , of course on a complete new build it was not a problem.
