I might be wrong, but it appears to me like they’re making the most out of Southampton’s bigger studio by not having the set form a strict rectangle - it looks like the left hand side (closest to the tower) is angled to make the set a bit bigger?

None of these sets are rectangular and outside of height they are all identical sizes and layouts - which is more akin to Norwich's studio shape, trapezoid.

Southampton's is more noticeable because of the size of the studio floor; the cameras are set back for long zooms at the top of the programme, as there is space behind them to move (I suspect, but don't quote me) the new set is installed at 90 degrees to the previous one to give as much space behind the cameras as is possible.

More interestingly is the strip of LEDs along the bottom of the screens that faces towards the cameras under the pillar - this is on all the sets but has only ever been seen on air from S'ton.
