Got it just before bed, I let my guard down!

Finally got the one I wanted from this Immersive!! I specifically took over R and even Sakaki couldn't help but smirk 😏 For a Silph Co. building, it feels really lived-in. Is it a Koga or Giovanni's mansion? Or maybe it's Saffron City if they've retreated there and it's cluttered? 🤔 I remember in G/S, some loyal subordinates were trying hard to take over the radio tower to contact Sakaki... So lucky to get this amazing shot that makes me want to speculate!!
