This map of mine is also part of a real-life location: http://csgo.gamebanana.com/maps/177542
You can see that the gameplay is stale and it's too complicated, but I'm sure that I can make it more balanced would I spend a few days of tweaking to it. Right now T arrives a little earlier than CT's at bombsite A, but that's basically it.
What I want to share with you as a tip is that you can really make it look like the real thing, it's just that you sometimes should make a few exceptions here and there simply because trying to recreate it a 100% is simply impossible. For instance, the middle part of the court of my castle was supposed to be a cutoff in real life, which I could have added but it would just obbliterate the A site, instead I designed an imaginary japanese terrace that openly seperates the incourt from where you can plant and where not. All of the interiors are also imaginated, since these where hard to see from pictures (the style is to be found everywhere, but the layout is hard, except for some plans which are unsuitable for gameplay).
Anyhow there are many things I need to do in order to make it playable, such as removing the entire upper floors, balancing T spawn etc.
I'm sure you can bring this to a good end, but start now in Hammer to see what goes and what doesn't.
