Well, I want to build two-level castle,
on the first level of which there should be a minor town (up to 40 houses) and on the second is the mansion and barracks for the castle’s guard. How much would I really need resources to have this project done?
If you wanted to do it with “authentic” methods,you’d be looking at on the order of a hundred workers over five or ten years.
(Or a couple dozen over a couple decades, which seems to be the time scale of the Guedelon project.)
If you were willing to build it somewhere with relatively cheap labor, that translates into perhaps a couple tens of millions of dollars.
But of course there aren’t so many skilled masons, stone-carvers, etc. these days, so they command a price premium, which would increase the price a bit.
But of course there are other options available in the 21st century–mainly replacing quasi-slave-labor with fossil-fuel-powered tools (with their own ethical trade-offs).
So some parts, like digging a moat, excavating and transporting large stones, etc. would be much easier/cheaper today, if you weren’t a purist about construction methods.
There have been many attempts to build modern-day castles over the past couple centuries, most of them atrociously ugly to the eye of anyone who appreciates the real thing.
But there have been some rather nice ones– Castell Coch in Wales is quite well executed; Castello de Amorosa in the Napa valley appears to have avoided many of the usual pitfalls.
Common fatal flaws are having stone-work that looks nothing like actual masonry and adding totally implausible and out-of-place architectural flourishes.
So if you’re serious, I’d have a look at some of these attempts before spending your $20M, to help avoid repeating their mistakes.
How can I build a model castle?
If a billionaire wanted a castle built for them in America, what company would they hire to build it?
Why we need to build a commercial building?
Why didn’t the Chinese build castles?
If I wanted to build my own car from the ground up, what legal and educational steps would I need to take to do so?
You will need land for the castle to build on,the stone to build with, the water to irrigate, the civil engineers and architects to design your ideal castle, the geologists to evaluate the condition of soil and rock and etc.
All in all, what you need exactly is money.
Once you have money, many people will come to you automatically, dreaming to be hired by you to build the castle for you.
In any project like this the resources ‘needed’ are flexible, depending on what you have.
There is a saying in project management: fast, cheap, good. Pick any two.
In the US (I live in Washington State) you’d need access to heavy equipment, masons, and a lot of rock and cement.
What you’re trying to protect from controls the design; you do realize that gunpowder made castles obsolete, right?
If you still want to proceed you might be talking about 40-100 acres and anywhere from $50-500 million.
It could go higher – much higher. If you have a forced peasant workforce, it could be a lot less.
First, you would need is a time machine which would take you in a time, when castles were made.
After reaching in those times, you would need to be a king there and would need at least hundreds of acres of land with a good vantage.
Then you need the water and building materials to build the castle and for the use in inhabited castle later.
So it would be good if you use locally available materials may be stone, lime etc.
Then with the help of an architect and landscape architect like me and few contractors, you would be able to build a castle in 2 years of time.
