yeah thats alot more involved than i'd expected, Tris obviously checked up in the roof for any loadbearing beams lobbing down on the brick in that area? have a look at subi hotel next time you're down there, we created wall openings & used a couple of PFC's as lintels, they sit flush with the brickwork and it makes them a feature, i recon it would look good if your going for the industrial chic look
