I assure you that Brazil is a lot closer to Antarctica than Iran. You will just have to trust me on that.
The reason I linked the Brazilian base is that I found a price tag for it. $100M. In the interests of determining how much Iran would likely need to spend to build a base as per the article at the start of this whole thread.
However, as someone else intimated, the Brazilian base is a large, luxury build out.
Of course an Antarctic base is rightfully at the very top of all the national projects Iran should be pursuing. Absolutely! Especially when allocating their national treasure and focus. I can not possibly even start to think of what else might even come close.
However, if someone has some $ figure for a slightly more... frugal, existing example for the Iranians to consider, just in case the spoil-sports at the top of the regime do not fund it quite at the level it properly deserves - what with Iran's honour and all at stake here - enquiring minds would love to see that example.
For decades Antarctica hosted only the simplest huts as human shelters - but architecture in the coldest, driest, windiest continent is getting snazzier.
