Is the construction project feasible? Is our budget sufficient for it?

I can roughly tell you the bigger items off the top of my head. Overall, I would have to check the list tonight.

Additional construction costs (notary, insurance, connections, ...) approx. 20,000
Shell construction 174,000
Roof including exposed roof truss in the garage and sheet metal roof on the bay window 34,000
Heating (air heat pump with 1200l buffer and underfloor heating in the whole house) 43,000
Central ventilation system 8,500
Kitchen 20,000
Floors are calculated at €50/m2 (will be laid by ourselves, and we will probably choose one that is a few euros cheaper)
Screed €5,750
Windows 20,000
Raff store 10,000
Garage door 3,100
Front door 6,000
Paving 5,000 (laid by ourselves)
Bathroom fittings 17,000
Fireplace 13,000

Well, half is still missing... Don't get me wrong, I don't want to question that at all. But I think that would be significantly at the lower end of the range you typically hear about these days. As of today, we are coming in a similar direction... however, with 40sqm less and a carport...

I calculated backwards:

500,000
- Buffer 20,000 (?)
- Double garage 35,000
- Outdoor facilities 25,000
- Kitchen 20,000 (you listed above)

400,000

- Additional construction costs 30,000

370,000

- Basement 60,000

310,000 / 184sqm = €1,685 per sqm

...with high-quality fittings? Phew... or am I making a mistake here?

But congratulations if it works

Well, half is missing

As I said, these are just the numbers I have memorized right now and that are fixed or have written offers.

€6500 for the interior doors just came to mind.

However, we have by far not planned that much for the outdoor facilities. Basically nothing is included except paving for the terrace and the lawn. Since we have a front loader and a vibrating plate, we don’t need a landscaper or anything similar. A terrace roof is also not planned for the time being.

The windows are aluminum-plastic. High quality there means well made. Aluminum-wood would have cost an additional 3000.
The ventilation system is complete. But we were really lucky to get a very, very good offer.
Plastering definitely doesn't cost 40,000. It will be somewhere around 30,000. At least not here in the countryside.
We will do the painting ourselves. Paint is budgeted at €2,000.

You’ll easily need €2,000 for paint inside. What about outside? And plastering for 30,000 is no chance, not even in the countryside.

Electricity, satellite, and LAN are still missing in the list.

It's already realistic, only the screed seems very cheap to me. .

We pay 3500€ (gross) for the calcium sulfate bonded heated screed and cement screed in wet rooms. Area 147 sqm, this also includes the leveling insulation layer. It is even laid by someone who is also a screed expert in addition. So the price is indeed realistic.

We have an offer for a single garage (but oversized) for 9,500€ gross. A double garage at 35,000 is exaggerated, then I would recommend continuing to look and negotiate.

In my opinion, it's enough, especially with all the own work.

You'll easily need 2000 paint for the interior. What about the exterior? And plastering 30,000 is no chance, not even in the countryside.

That still depends on whether the exterior is to be insulated; we are paying 45,000€ gross for interior and exterior work, drywall work plus the ETICS insulation. The insulation alone costs about 21,000€ and can theoretically be deducted.

And we are building near Frankfurt, so not exactly in the countryside.
