I find that plopping this and adding roads works fine, but each separate building is individually affected by crime, and, after placing roads to allow police cars to access it, those police cars never move from a position they take on the road (not how they work on normal buildings).
My impression is that the way the various parts are combined in this version messes with access for police vehicles. I didn't have any fire or sickness while testing this.

I think the seperate buildings work better that this complete version as I have never seen that happen with that version.

This beautiful Castle is amazing. It used it for a very successful park near my main public transport hub and it works wonderfully. Easy to setup and great to implement. Many thanks for this beauty, see: https://youtu.be/jOu0lPlXUis

use procedural object it will remove the props but also remove the need for roads

@Brandon
I just added like a private road to connect them to main road, but otherwise its normal not to have road access when put down

I place it by a road and it always show no road acces icon? is that normal? its kind of annoying, dispite being a great asset :)

@gbelliot try the Road Anarchy Mod

How do I get road access to this building. Seems to not build on a road.

great !!
