That is fascinating insight. There would probably have been depth to do that on Park End and Gwladys, which alone would have put us up to about 50k I imagine.By approx 1980. The club had plans drawn up to continue the mainstand down to ground level (getting rid of the enclosure) creating a 2 tier stand.... and then replicating that format on all sides to slightly different proportions, but same height. Creating an all-seater stadium. I've only seen the cross sections and not the plan view, so I'm not sure how the corners would've been handled. I would say that it was just a study, as it showed clearly that the area for the Bullens Road stand was not deep enough. I can only imagine that the drop in attendances at that time and the estimated costs scuppered any further investigation. The concept still included the same type of roof design as the mainstand.... with supporting columns (not goalpost truss or cantilevers), but that may have been only illustrative. The drawings were done by Littlewoods architecture department. John Moores was getting on by then and I think his sons had diverted their attentions to the other lot by then? So maybe there was less impetus for it all too, by that point.
Then we could have done something mad like La Bombonera for the Bullens!
