Construction costs in BW for a single-family house with a 200m2 basement and double garage

So we want to build the same size with WU basement in BW. The offers range SF between 400 without BN and 500 with BN. But then completely tiled and painted. However, without gimmicks like controlled residential ventilation or KNX. But electric shutters everywhere. Without outdoor facilities and garage. But then you should probably manage with 80k for both??? Prefabricated garage costs around 20k, the rest for outside.

But if a very high standard is desired in a 200/250 sqm villa (or similar), you don’t frame it with hexagonal stones. You should have the outdoor area nicely done by a garden landscaper; that costs money. With a 60-hour week, you should be able to have the main work done rather than saving on the flowerbed edges. Also, you probably don’t want to save on an intelligent electrical system...

People, please don't let yourselves be milked like that!

Where does the OP write anything about a high standard or landscape gardener in the garden? Didn’t he even say that he would save money on the outdoor facilities?

You don’t have to transfer everything you like to install or would like to install yourself onto others. Not everyone wants KNX, controlled residential ventilation, 200sqm terrace, automatic garden irrigation, etc.

A terrace, fence, and lawn area would be completely sufficient for me. Everything else just creates unnecessary work. And if you work 60 hours, you definitely don’t have the time or desire for that.

A rough rule of thumb for the total costs is the #turnkey# price from the house provider plus 30% incidental costs for a move-in ready new build. Move-in ready then means including all additional construction and civil engineering costs, the furnishings (with kitchen and all lamps), and the finished outdoor facilities. In our case, the questioner's household has just under 6000€ net monthly income. They should not spend more than 30% of that on interest and repayment. With an annuity of 5% (thus at least 3% repayment) we have a maximum loan volume of 480,000€. With 60,000€ equity, the new build may then cost a total of 540,000€. And with the 30% rule from the beginning, the turnkey house alone must not cost more than 415,000 euros. With a higher standard of 2000€/m2, they arrive quite exactly at 207m2 living space. Alternatively calculated, they do not spend more than 3 bruto annual salaries on their project. But that does not change the magnitude much....

A rough rule of thumb for total costs is the #turnkey# price of the house provider +30% incidental costs for a move-in ready new build. Move-in ready means including all secondary construction and civil engineering costs, furnishings (with kitchen and all lamps), and the finished outdoor area. In our case, the household of the questioner has just under €6000 monthly net income. He should not spend more than 30% of that on interest and repayment. With an annuity of 5% (i.e., at least 3% repayment), we thus have a maximum loan volume of €480,000. With €60,000 equity, the new build may then cost a total of €540,000. And with the 30% rule from the beginning, the turnkey house alone must not cost more than €415,000. With a high standard of €2000/m2, he thus gets pretty exactly 207 m2 of living space. Alternatively calculated, he does not spend more than 3 gross annual salaries on his project. This does not change the scale much....

Then that’s certainly enough. If I now calculate 400k +30%, I am at 520k. Then he still has enough buffer for a €50,000 kitchen.

Then that's more than enough. If I calculate 400k +30%, I come to 520k. Then he still has enough buffer for a €50k kitchen

But only if he can do without the garage for €40,000 and parquet beyond €100/m2 and the occasional marble cladding[emoji6]
But it's a conservative financial plan that should work.
