Although it's nice to imagine that one could assemble these buildings from current parts, I have serious doubts they actually exist. Even if they do, there's the major problem of procuring them from DS.
I guess I should try and wrestle with DS here for the parts!
"Sorry, all columns sold out. Try ordering one every two months for six years. Here's a shutter for the window. Sorry, the window frame itself is sold out. Try again in four months."
This sounds exactly like my experience with DS!
"Yes, we have that helmet in stock"
"Great! I need 80, please."
"Well we only have 3."
"Okay, I guess I'll take them. I also need 80 of the crests that go with them."
"Sorry, we don't have any crests in stock. Try back in six weeks when we get our shipment from Germany and we might have 5 of them."
And then when I finally get my order 0 of the 3 are included!
It has taken the better part of a year and numerous orders from DS and I still don't have my Roman army together! I shiver thinking of how long it would take to receive the parts to build a Roman building!
