Our new vacation home is taking shape.

It's amazing what 0.5 btc will give you, considering what I paid for it back in the days.
Now it may sound cheap, but a decade from now, the same amount will probably be enough for a big mansion.
So, another half Bitcoin and you will have actual doors, windows, heating, electricity and flooring?
Not bad at all

That's the final cost actually, including windows, AC, flooring and what not.
This is Thailand, so material and labor is very cheap compared to any western country.
