toxicmolotof3 Dec 2017 22:18The never-ending discussion about children’s rooms.
I used to have 9sqm (approximately 97 sq ft) and survived. My children have 12sqm (approximately 129 sq ft) and will survive as well.
Of course, 15, 18, or 25sqm (approximately 161, 194, or 269 sq ft) are great. But no child gets harmed by having only 9sqm.
In social housing, the minimum size for a children’s room is generally 10sqm (approximately 108 sq ft) (although it’s not specified how many children can share it).
Now, regarding the costs:
I’m not fully convinced by your calculation. You can estimate 10% for additional building costs (building permit fees, contractor overhead, etc.) on projects starting at 400k, but not for your budget-saving plan. Similarly, the rest seems quite optimistic for exterior work and the garden, so you will most likely end up spending significantly more.
However, there are other experts here who can break that down better. Somehow, I see at least a 3, maybe even a 4 in front of the total cost for the floor plan including the plot. And I know what our house cost three years ago.

Always this discussion about children's rooms.
I used to have 9 square meters (97 square feet) and survived. My children have 12 square meters (129 square feet) and they will survive too.
Of course, 15, 18, or 25 square meters (161, 194, or 269 square feet) are great. But no child will be harmed by 9 square meters (97 square feet).
In social housing, it is often required that a children's room must have at least 10 square meters (108 square feet) – although it is not defined how many children may share it.I also grew up with 9 square meters (97 square feet) and later really appreciated my 12 square meters (129 square feet). Now, with my son, I have a different perspective. He has just under 12 square meters (129 square feet), and the room is quite elongated. I find this sufficient. The other children’s room is more square-shaped with just under 11 square meters (118 square feet). That’s much harder to furnish in a practical way. Ten square meters (108 square feet) and square? Good luck! The bed ends up right against the head wall, and after two steps, you’re already at the closet. You can squeeze a small cabinet into one corner for the TV.
Yes, it all works. But if I am building a $240k house, I should have a really well-thought-out plan. Do I need four children’s rooms of 10 square meters (108 square feet) each, or would a shared bedroom for sleeping and a larger playroom also work? That’s how we plan to do it, as long as the kids accept it.
If I plan for at least three children and have only the budget available, I should consider alternatives.

[emoji33] I read something about 4 children's rooms...3 are mandatory. 4 would be nice.kbt09 schrieb:
Planning a floor plan without having a plot of land is purely theoretical. That’s true, even if the (preferred) building area is already “set.” There can be very different lot shapes even among otherwise similar plots, and nowadays new developments are often divided up: one section might have single-family houses with one full story, while another has duplexes with two full stories, for example. Or the exact plot you want might be sold to a developer who then lets you “choose” options like a kitchen with or without a wall to the living room, carport or garage.
On the other hand, that doesn’t mean you shouldn’t start thinking about floor plan design more consciously. Every beginning is difficult, and in the end you may become skilled enough to realize that you might want to look for your ideal plot in a different development. Others also go through a phase of trial and error at first—the main thing is that in the end you end up with a suitable house.
