The club / contractors might be saying it's "more distinguishable" and that metal panels with the continuation of the criss cross motif being replaced by windows that dont have it is going to enhance the (unobservable) criss crosses on the brickwork, but that doesn't mean it's true.
But this is all down to Meis trying to curry favour with fans who he thought were all on board with a design on the brickwork just so he could get the stadium architectural gig.
It's a failure of epic proportions. This stadium is costing £700M and to chop and change on the facade that will cover it and be the face of the stadium to the world is unforgivable. It's been a case of too many cooks on that design. Meis had his input, the likes of UNESCO and Historic England had their say on it, then we had Pattern Design. It's absolutely pathetic.
