Assessment of construction costs for a single-family house in NRW (current situation)

So over 4300€/sqm? Wow.
I already know several who are still building for 2500€/sqm.
I do wonder what is included in your price.

By the time we start building (beginning of Sept. 2022), the spiral will have turned a bit more.
If it is less than the tender, I’ll be fine with that.
Calculating with 3500 and then being shocked by 3700€ is just not my thing.

Basically, it doesn’t help the OP either.
This is about breaking down the expected costs.
And here architects calculate with net construction costs, since the fee is based on this.

Alright, so I understand that we should calculate with 3000€ per sqm. Can I completely exclude the approximately 20sqm office/cellar room as living space if we leave the cellar in its raw state for now and finish the room ourselves later as needed..?

So the calculation would be:
3000 x 130sqm (excluding cellar room) = 390,000€
+ cellar 100,000€
+ garage 8,000€
+ KNX 50,000€
+ photovoltaic 15,000€
+ air conditioning 10,000€

== 573,000€ + 10% ancillary construction costs = 630,300€

Is that still realistic considering material shortages + the Ukraine war?

Your architect wants to calculate with 2,700 EUR, most people in the forum are more in the direction of 3,000, and you want to calculate with 2,500?

Yes, then just go ahead.

- Garage for 8k you get at the hardware store as a kit
- KNX as said can be enough, since electrical and land are already included in the construction price but nobody knows what exactly you imagine under KNX
- Photovoltaics how many KW? At the beginning you also calculated with a storage. My neighbor got an offer last week in BW for 9.9kw + storage for 26k.
- I don’t know anything about air conditioning.
- Additional costs are fine by me.

Still missing:

- Architect
- Outdoor facilities
- Kitchen
- Furniture
- Lights
- Extra charges for more expensive versions that are not included in an average price/sqm. These would be, geothermal heat pump, 2 dormers, clinker facade, light well, etc.

Of course, you can also keep turning the numbers until it’s just barely over 600k :D

Alright, then I have understood to rather calculate with 3000€ per sqm.
Can I completely exclude the approx. 20sqm office / basement room from the living space if we leave the basement initially in its rough condition and finish the room later ourselves as needed..?

So one would calculate:
3000 x 130 sqm (basement room out) = 390,000€
+ basement 100,000€
+ garage 8,000€
+ KNX 50,000€
+ photovoltaics 15,000€
+ air conditioning 10,000€

== 573,000€ + 10% additional construction costs = 630,300€

Is that still realistic regarding material shortages + Ukraine war?

Mmh...I’m out here then... if you approach the thing like the thread here, it won’t work...

My crystal ball has no answer for that ;). I bought PUR insulation last weekend. The warehouse was bursting at the seams. On the other hand, I have an insurance claim - I need a new pane for a window. There, I have to wait 4-6 weeks just for the glass. A big problem is the immense demand that we still have.

Can I completely exclude the approximately 20sqm office / basement room as living space if we leave the basement in its rough state for now and finish the room ourselves later as needed..?

You’d better think about painting the basement or increasing the budget. Finishing the basement room later doesn’t help. Insulation must be done now, you also need the room height and the windows. You can’t just install the heating (underfloor heating) later either. Chase the wiring again? Then there’s only the floor covering and wall/ceiling paint left. That won’t make a difference. You’re building too big or have too big wishes or simply too small a budget.

As already written here, how do you want to get only 130m2 with these external dimensions? It’s best if you show the plan or at least clarify the exact living areas. Many have already shown you a good way here, cross out the extreme examples (Malunga and Statistisches Bundesamt) at both ends, then you will end up with 2500,- /m2 for "standard" up to 3000,- /m2 (your wishes!). It won’t get more precise, we don’t have a crystal ball, these are approximate values. The war doesn’t have anything to do with it for now; you can leave that aside for the time being. A garage for 8k is never going to happen, with 100k for the basement you’ve rounded up well for it. If it gets tight, I would rather question the attic (not yet amortized) or scale down the equipment a bit. On top of the above approximate values come the incidental costs, but not the heating etc. However, usually still floor coverings/painting.

Just have the house offered to you by a [GU] or prefabricated house manufacturer exactly as you want and take a look at the prices. I did the same. Rounding up or down doesn't help at all if you can't establish a real reference.
