It depends of the point of view. In some countries people like to live in big houses, paying huge mortgages for something they don't always need. Other people are using 20 - 30 m2 the best they can, everything us multipurpose because that's the space they can afford (look at China and Japan). At the end you have to decide what you need and what's important to you.
That house is lovely, rustic and has everything you need. I'd be happy to have a house like that in a quite place, far from pollution and noise. If you're asking me, I'm definitely not a big fan of big houses, just to show off and have more than your neighbor or friends etc. I'd rather use the extra money for traveling etc.
