Despite the bottom beam, the whole thing is probably still a little wobbly, so prop it up against a wall and we can get the shelves in for extra sturdiness. Starting from the bottom, line up your corner cut-outs and place each shelf on their side boards, keeping them symmetrical all the way up to the top – where your un-cut board will sit. Once they’re all placed, use long screws to fix them in place at the corners.
TOP TIP: Want to make sure your wardrobe is rock solid? Now’s your chance to fix the beams and boards together with construction plates too.
