If we can we should. Would be the cheapest option if it drives a promotion from the NL. Even if seats have to stay then our fans can just stand. Away fans in the South with access via Roots Hall Ave should have happened years ago for policing reasons as well as our own.
The North Bank at the moment is an advantage to the away team. If you sitting in the East the away fans drown out the Blue Voice. RH has become an easy touch and that has to stop. Its the thing us fans can have out biggest influence on.
The problem you have with doing anything on the North or West Stands is the condition of the existing in-situ concrete. Without conducting pull and/or load tests, it is difficult to ascertain whether you can install anything more than a tip-up seat.
Most commercially sensible option would be to fit safe-standing rails - that way it would be compliant for when/if we go back through the leagues. However, the tread depth is so limited in the North (hazard a guess at sub-700mm depth which is 100mm below the industry recommended minimum) that I am not sure it would be permissible with the SGSA (Safety at Sports Grounds Authority) who would take a keen interest in any transformation to standing.
I would assume that any home occupation of the North Stand would be temporary, as the access/egress arrangements and ease of segregation anywhere else in the ground would be complicated at best.
We are just in the final throws of completing a retrofit installation at a major stadium in London (which will remain nameless for now) to cater for persistent standing in the away area.
I'd be happy to pop down to the Hall to conduct an initial survey if anybody at the Club had an appetite for this.
