No, our plans didn't change after we'd started building. Costs went up because we chose to pursue a more expensive scheme, not because we changed our minds halfway through building something else!
The old plans were scrapped entirely, and in 2015 planning permission was sought for the current scheme (designed by a completely different architect). It was gained pretty quickly because there was already planning permission for a big new stadium on that site. Only after planning permission was gained for the entirety of the new scheme did building work begin. We didn't change to the new NFL-capable stadium during the build, and the brief was solid before building work began, but it was a brief for a higher-spec, more expensive stadium than the old one revealed in 2008.*
So back to this thread - unless the club and/or the planning committee feel like they've really got something major wrong or the scheme as revealed suddenly becomes unviable, there are unlikely to be big changes between what's revealed and what's built. Especially if the timelines are tight and there's a need to get this stadium done for 2022. The only exception I can think would be if there are two distinct sets of plans, one dependent on the Commonwealth Games and the other not.
* There have been two minor changes since the building work started - the design of the West entrance has become more curved after the planning committee raised concerns about its aesthetics, and there's been a minor tweak to the internal seating layout. But nothing major.
I should have been more specific. Spurs changed their brief, and that why it got more expensive. The change in brief, meant a change in design, which meant a change in cost. Prior to the construction stages.
There are always minor tweaks through a build as you mention.
