That's not easy. Extending over the road would make the new seats miles from the pitch and unless you created a two tier stand, they'd have shit views. The Kop would no longer be the Kop, just another stand. The way to go for extra, cheap capacity on the Kop is safe standing but there are reasons why that won't happen anytime soon. Also the Albert has been kept for heritage reasons - just smashing it down would be a shame. And the future development is for the area, but the club. The area is not just about the club - demolishing churches and historic pubs and blocking the views along residential streets would be a massive 'fuck off' to the area.
I think if it ever gets done it has to be single tiered, two tiers isn't an option for me. And agree about the Albert, although there may be ways of incorporating it, moving it brick by brick etc.
Out of interest, do you know what the maximum distance could be to the back of a single tiered stand? (I understand your point about shit views, but if you weren't paying much it wouldn't matter so much. I didn't see a lot in the 80's when I was 15 and getting thrown all over the place!)
I do think a lot about a ground where people could walk up for 15-20 quid on a Saturday for the Kop. It's not in keeping with modern football at all, but it'd be great for Liverpool to do something a bit different. Can't see it with FSG though, they're running a tight financial ship. Maybe with some other investment, part fan funding or different owners they'd look at it differently.
