A facade technique for corners. The important part is this, which may be hard to source. The offset is a half-plate on each side of the dark bley block. I would love to see a solution that is solid and only uses in-production parts.:
I'm sure loads of people have already done this... don't know why I didn't think of it sooner! Using jumpers with 1x4 bricks with grooves. Not entirely sure what use it will be - I think it will be great to create stable interlocking sections in models (the three parts are not attached) Breakdown is here A use of this technique is here Thought of a name for this technique - the Groovy Jumper!
