There is clearly a forthcoming change from the consented Heckstension scheme.
The official news release states:
'The redevelopment will also deliver substantial football infrastructure benefits, including the creation of approximately 500 square metres of new first-team changing, medical and physiotherapy facilities, alongside the upgrade of all player competition areas. '
This is not within the consented scheme. Something similar was in the Purslow Plans, situated around a new tunnel in the corner of the wraparound between the Trinity and the New North Stand.
Furthermore, from Tanswells article:
'The Athletic has seen copies of the redevelopment proposals' - this indicates there are new proposals which are not public domain.
'The new North Stand will wrap around into the neighbouring main Trinity Stand' - this was clearly not the case with the last heckstension.
Put the dots together - the design is changing again.
Can only assume they figured this was a bonus route they could go down by closing the stand.
