Looks nice. a bit different than the game's style but if there were a few more it might look good. Tho i've never gotten to see the offices yet ingame.
It is hard later game to keep the required amount of inhabitants, retail, parks, etc all around to reach the later levels, so adding this building without any extra provision doesn't do it justice. It'd be better if it also added an amount of each that would be required for office highrise in its vicinity.
It could even provide hospital coverage +1 or so in terms of a apothecary or daycare center inside, f.e.
Unless i'm missing sumthing, it seemed ingame it doesn't add anything, no leisure or office or retail.
Maybe due to modding skills or an oversight, it would be advantageous if it got 'boosted'
