Building a Ytong house ... - does it make sense?

These are prices for the kit without masonry work without interior finishing without electrical, heating, sanitary

What are the assessments and experiences regarding this?

I see it very similarly to My experience is that experience and knowledge of the subject help to commission, accompany, and supervise a good and affordable house as a builder. Your question about Ytong gives me the impression that you are fairly new to the subject. That is completely okay. You can build very affordably with Ytong. You can also do so with other companies and building materials. What you need first is an idea of which tasks need to be done before you can live in the house. Your price approach is doable but very ambitious and beyond the conception of many. Whenever you want to achieve something extraordinary, you have to dive deeply into the subject—the conception of many is not made up, but is based on experience and the exchange about it. Choosing the provider "Ytong" alone will not get you to the goal of realizing the price you mentioned for a city villa. Much development is still needed for that.

At the company Ytong, you basically get a bunch of documentation (structural analysis, building permit, thermal insulation certificate, etc.) and multiple truckloads of blocks and windows, delivered free to the curb.

The simplest city villa is available for 127,000 euros with 157 m2.

You are allowed to excavate the pit, gravel it and build the floor slab yourself (10,000 to 20,000 euros). You can also gravel the crane area and set up the crane yourself. Then you lay the stones on the ground floor. Then one last time someone from Ytong comes and places the ceiling to the upper floor, installs a concrete staircase and builds the roof structure. You do the ceilings yourself. Also install the windows yourself. If you really still have annual vacation and your discs hold out, you can mill slots for the electrical wiring. Then an electrician must do the connections. No material is included; including a willing electrician, plan on around 10,000 euros for a simple installation.

Simple gas heating from a professional with everything costs around 20,000 euros, rather 30,000 euros. Upwards it depends on the heating concept. Bathroom and co. at least another 15,000 euros, rather 25,000 euros. I would never do that myself unless I was directly in the trade. Now you can have screed laid, another 5,000 euros. Exterior plaster with scaffolding another good 10,000 euros, rather 15,000 euros. Interior plaster and sanding to Q3 quality another similar amount.

So that is another good 100,000 euros on top of the kit price. Let's say 230,000 to 240,000 euros. So around 1,600 euros per m2 with a lot of own work and saying "no" very often when asked "should it be a bit nicer". That is then the house price.

Whereby craftsmen tend to add 5 to 10% per year, so depending on the start of construction you can add something more. Also, no upgrades are included; this is all calculated simply standard.

And still missing are some "small things" like gutters, roof insulation including drywall or possibly a cistern and other incidental costs, especially for utility connections. Plus outdoor facilities, garage, small furniture and kitchen. That then depends on your wishes, those of the municipality, and the plot.

A construction manager and/or building savings contract would be strongly recommended, so another 5 to 10,000 euros.

Please continue to observe and learn!!! By the way, Ytong is also available cheaper under other brand names!

Hb equals Bremen? In the North, almost every builder uses aerated concrete, brand names Ytong, Hebel, Porit, Hansabeton. All these blocks are almost the same. Our builder actually used original Ytong because he appreciated the consistent delivery quality, the blocks are intact, smooth, dimensionally accurate. Meanwhile, I see that he has switched to Hansa. They must have offered him a good deal. So, you don't have to order such a house directly from Ytong, it is available everywhere in the North. The material has advantages and disadvantages. Among the latter is certainly the poor sound insulation. And the material is porous, you have to be careful when drilling if you want to fix something on the walls. Sound insulation always comes from mass, since aerated concrete is full of air bubbles, it is light and not massive. But that is where the main advantage comes from. The very good thermal insulation value without any styrofoam. You can build a KFW 55 house with aerated concrete without needing a thermal insulation system, just block plus plaster plus facade paint. No algae-covered wall, no damp wall, nothing. Like in the old days. Block plaster good. It also saves labor costs. It comes in large formats and therefore the shell construction progresses quickly. I would always choose it again. In my opinion, in the era of thermal insulation, it is the best block you can get. K.

The company Ytong offers quite nice houses. However, we don’t understand anything about it and neither can nor want to handle it ourselves.

Question-oriented answer)
You are apparently talking about kit houses. Such houses only make sense if you are a self-builder – and if you don’t want to change a jot of the package. Ordering the building materials package "Miracoli for city villa" and then having it processed by a professional shell builder is utter nonsense. That large-format aerated concrete plan blocks have very good suitability for DIY can really only be evaluated by DIYers.

Solution-oriented answer)
Your thread history shows a complex diffuse perplexity that made me hesitate whether to give the above question-oriented answer at all. I have come to the conclusion: not really for you, but only for readers. The answer for you is different, namely: clarify your financing and take the result of your budget to an architect. Give him a wish list and tell him which Ytong model you would have chosen. And then don’t be surprised about anything. I see his possible reactions somewhere between the following two extremes: A) he sees worlds apart between the example house and the wish list, then let him plan a house freely based on the wish list; B) he sees this house-building mix as it is as a (in terms of congruence with your wishes!) coherent thing, then formulate the next commission to him as: procure for me the people who will build the turnkey house from it and supervise this construction.

Otherwise, I see you will remain infinitely diffusely perplexed and next year ask whether a house made of steel or salt dough would be the solution.
