Please tell me they are not the same people that did the Docklands stadium. That been the biggest farce I seen to build stadium on wrong angle for sunlight and not taking into consideration the glare on tv if roof open. Cannot grow proper grass well and virtually has to be used as an indoor stadium.
I think you might find the Victorian Govt moved the orientation of Docklands against the specific advice of the architects to fit into the precinct as designed.
Also the roof was always going to be a problem with the grass no matter what direction it faced. The closing roof as design point was the major driver of that. They wanted a closable roof, they got, but it comes with trade offs.
You might also note that the MCG is s**t at grass growing in winter too. grow lights, massive turf replacement etc.
glare is also a problem at the G. There are days where day games from the MCG are unwatchable due to the difference between the shade generated by the northern side of the ground and the unshaded areas.
Wembley, Arsenal, Man U, and almost all major stadiums with natural grass surfaces use grow lights because the size of the stadiums work against sun getting to the surface no matter the roof.
This one will be no different. Grow lights, turf replacement etc. the same thing as Etihad and the MCG.
