I always find the argument "what do you want with xy sqm" quite lame. Everyone should live on as many square meters as they want and can/want to afford. I know people who have 350 sqm and it could still be bigger :) If we had a much bigger budget, we would also build more than 225 sqm + 60 sqm attic. Just in the living room, I would like a "built-in" huge sofa.. like US style :) I discussed this with the architect and we quickly came to the conclusion -> for it to look good, you need at least 100 sqm just for the living room. Better even more.
Some here in the forum think... a children's bathroom is luxury or a kitchen island etc. All nonsense.. the size of the house is luxury or a big indoor pool.. that quickly costs alone 200,000 EUR.
So.. if the original poster has a budget.. gladly really a lot of sqm including cleaning help (which won't really make a big difference anyway) if he feels like it. If not -> build smaller. It's as simple as that ;)
Edit: I just thought of something.. one person here in the forum once presented his house including pictures.. that was the only real luxury house I have seen here so far ;) I think he also wrote something about 1.5 or 1.7 million. It looked very good and I really liked it :)
The "problem" is, however, that the original poster apparently can't just afford such a big bunker. And if we're honest, no one really needs 200 sqm (unless special rooms like an office are needed). What each individual would like to have is a completely different matter.
We once looked at a condominium with 250 sqm. It was great! Sauna, the shower was as big as our current bathroom, built-in bathtub, 3 balconies, huge bedroom and 2 very spacious children's rooms each with their own full bathroom, open fireplace, many windows, etc. Even affordable, but completely off our needs because it was simply too big and hardly manageable.
With 120 sqm (2 children's rooms, bedroom, bathroom, guest toilet, living room, kitchen, utility room) you can manage a single-family home that basically suffices. If you
want more, then you have to be willing to pay the extra cost.
Now we can argue about the definition of luxury. But I’m not in the mood for that :p
A second bathroom (toilet, sink) I find practical, an explicit children's bathroom (with toilet, tub, shower, ...) rather an additional burden (I have to clean it all :confused:) and yes, also luxury, as long as it isn’t really necessary (lots of kids or 2 girls, each spending half an hour in front of the mirror).
A built-in couch would be pure luxury for me, but cool! Our sofa (proudly 4 m wide, U-shaped) only occupies a generous corner of the living room.
