The office looks like awful 90s office decor taken to the extreme, and for that reason I love it. Anything that speaks to the time period of the original game is a good look in my book.
It's such an awful office to work in, though. I can't believe he doesn't have a button on that desk that lowers his chair down into something a lot cosier and more pleasant, maybe with a fireplace and a tiger skin rug. Then when the sensors indicate that someone is approaching his office he rapidly scoots up into his desk again. The cosy office can double as a bombshelter.
As we see in Episode:Shin-Ra, though, he doesn't want his desk to lead to anything like a bomb shelter. He did install one, but for Rufus's use. He refused to use it.
It was actually this that added a number of dimensions to his character. The fact that he installed it in the first place; the password to its door (Rufus's birthday -- described as a common password for the President to use, and a day he would never forget); the biting commentary of "'L' for 'Loser'"; and perhaps most of all: the fact he didn't try using the escape hatch to get away from Sephiroth.
That last one in particular sheds interesting light on the character.
