If 60,000 is too unaffordable. There may be other options. I can't vouch for any of these ideas but it could be interesting to think about.
A company known as "Inflation Dome" is selling an inflatable bar kiosk, here: https://www.evolutiondome.com/inflatable-structures/inflatable-kiosk/inflatable-bar-catering-kiosk
They don't list the price but it may be more affordable and in some ways cooler than a normal bar.
Places like amazon sell steel buildings which can be cheap in comparison to conventional buildings.
The price doesn't include the cost of plumbing, electrical, labor. Or the cost to construct a series of rooms inside the interior to house guests. Also can't comment on whether it conforms to building codes in different countries.
There could be potential for it though as the cost is relatively low in terms of square footage, etc.
