Construction Cost Estimation Baden-Württemberg

That is absolutely realistic for BaWü depending on the equipment and exact region. Especially since it sounds like somewhat upscale equipment.

Edit: However, for example, €9500 for sanitary material is immediately gone if you have two bathrooms. That can also quickly be too little.

Hello,
since I come from Bavaria I can only speak for our region and here that would be very expensive! But I think BaWü is a different price level, I like the breakdown of the trades, maybe you can take out one or two things from the offer and do them yourself.
Regards

What just comes to my mind...

Earthworks?
Are concrete works included in masonry works?
Is this actually an offer from a general contractor or a cost estimate from an architect?

I find that already a hefty price even if details are simply missing that are absolutely necessary for a calculation. In the end, it is nothing more than the bare price of a car without knowing the brand and optional equipment.

We are almost finished, a little bit of landscaping is still missing (leveling the ground, putting topsoil on and laying terrace slabs, where the material is already available and paid for) with a lot of extra stuff (65m of L-stones, photovoltaic, storage, lots of tiles, basement with underfloor heating, fireplace, controlled residential ventilation, blinds, lots of window area, lift-and-slide door, carport, 110sqm paved driveway, terrace roof with electric awning etc.) we are currently at €405k. So no more than €10k will be added! And that for 140sqm + 70sqm waterproof basement with 2 full floors as KFW55 with air-water heat pump in Bavaria around Nuremberg.

If I were you, I would get 2-3 more offers!

We didn’t sign anything. We had individual trades with offers that mostly met our wishes, and if something came up during the construction phase that we absolutely wanted to update, we said "do it"! For example, raffstores on the ground floor were not planned, only electric shutters, but we changed that before the shell builder asked us what kind of boxes to install. The same with the plaster; a week before the fine plaster was applied, we decided on solar plaster, it was like that with every trade.

But we had about 1.5 years lead time and also familiarized ourselves with the materials. So we built exactly as described. This saved us an estimated €50-70k or allowed us to do updates until no wish remained.

I am not against the construction method with a general contractor, but it is definitely not as flexible to the extent that one might need.

Didn't think there were such big differences between Bavaria and BaWü.

The 9500€ also seemed rather low to me in comparison. We have a guest toilet with 3 sqm and a bathroom with 12 sqm.

Removing things and assigning them yourself is possible and we would definitely do that.

The price should be pretty much "all in." The offer is from a local general contractor.

Did you always have an architect as a site manager then? Or who took over the site management?

We had a private construction coordinator who, in the same way, has built over 20 properties for himself and his own family over the years up to now. He was our former landlord. The architect only accompanied us up to the building permit. But he was also available to me for questions beyond that. Honestly, you can only do that if you know the trades and have worked with them for years. We ourselves were always 2-3 times a day on the construction site and were also able to give the trades answers to questions (breakthroughs in the base plate, etc.). I did the lighting planning, fire points, switch planning myself. My landlord then optimized it. That really kept my head spinning nonstop.
