Knallkörper3 Dec 2017 21:53Have you ever lived in a house or apartment with such tiny rooms? 10 m2 (108 sq ft) already feels quite cramped. A child's bedroom should definitely be a bit larger.

The whole floor plan design is an academic exercise without having the plot of land. That's true, especially the location of the dining room would need to be adjusted.
For me, it’s not just theoretical, but to calculate if it fits financially. I need a rough estimate. After that, we will take further steps, such as adjusting the disability insurance, term life insurance, etc., to align with the construction project.

But if you’re already investing so much money, shouldn’t you be able to afford 2 m² (22 sq ft) more for the children’s rooms?Also, take a look at the additional costs list in the forum. You’ll be surprised how many expenses you haven’t considered yet. Your budget is too tight.
chbest schrieb:
The idea is that the rooms upstairs are more functional, and that family life mainly happens in the central living area. Or what are you aiming at?All standard floor plans designed for a family of four offer exactly this.
I don’t see a clear pattern in the options you’ve collected online: sometimes it’s a bungalow, then a townhouse, and then a house with 5! bedrooms. Sometimes the open-plan living area is L-shaped, sometimes not. The last one even has a secondary entrance and a dormer window. All of these add extra costs.
Basically, you always like “the same thing,” which every house has.
But a house is much more than just the floor plan.
I think you’re simply attracted to the catalog price.
Your wish to stay within a budget of 280,000 requires some discipline.
Regarding your heading: wait to see if and which plot you can get at what price, and meanwhile talk to the house builders about what kind of house you can get from them for what price. Check the builders’ service specifications for hidden costs.
P.S. Even Town & Country only includes groundwork to a depth of 30cm (12 inches). This does not include, for example, soil removal, only storing it on the plot.
Additional construction-related costs will certainly be higher than the 22,000.
