The castle and the island, theory

[Conspiracy Theorist]

I never let reality get in the way of a good story.  I'm also pretty sure most castles wouldn't fit on the average lot in Chicago no matter what their state of repair. But I don't insist and won't defend it.

The Castle is a TARDIS, it’s exactly as big on the outside and inside as Jim requires at any one time.

Also note:  the workings on Demonreach are constructed in a single working spanning 5 different times (forming a time-dimension Pentacle).  So there is time-magic there.

And the Castle has similar runework.

And now it's decorated in blue.

Yeah.  It's just a matter of... did Marcone buy the block (or a hefty chunk of it)?

Or did he only buy the one lot (and the Castle is Tardis-like (bigger inside than out  )... i.e. Jim & the beta-readers messed up)?

He bought the Wrigley Field parking lots from earlier.....

Drum Castle in Scotland is probably about the right size given the constraints of the book. Not saying it's what Jim imagined necessarily but I think it works. Borthwick Castle (also in Scotland) would also work.

Yes not all castles are huge and Scottish / Borders Castles post 1000 AD fit the picture. That is post Merlin but pre -Eb which sounds right from Eb’s comments.
