Land planning / floor plan planning

heated

That's exactly what I mean.

? This is at least included in the base price at Viebrockhaus:

[*]Heat pump heating
[*]Underfloor cooling
[*]Central ventilation system
[*]Photovoltaic system
[*]Battery
[*]Air humidification
[*]Preparation for wallbox

All KFW40+

But this does not apply to the basement.
If you go with a basement, the costs increase to keep the house at the Kfw standard.

I did... I budgeted an additional 60k for extras and electrical in the list.

Just familiarize yourself here as a future builder. It’s already been stated here thousands of times that a catalog price hardly includes what you actually want.
The 60,000 will quickly slip away from your rather casual “what-does-the-world-cost” expectations, so that no money will be left for earthworks – even before the first spade: P

Do you really think that I am budgeting too tightly with 600k for house and garden?

Get informed!

and probably no one – building their first house in life – has drawn their floor plan right away...

Of course not. Sketches are best made on graph paper and without PC 3D animation...

...Quickly slip out of your rather casual "what-does-the-world-cost" ideas, so that no money is left for earthworks

No idea what that is supposed to mean and what I did to deserve it.

I also never mentioned anywhere that "no money might be left then." If I say that money probably won't be the problem, then you can just leave it at that. I calculate roughly because I want to know what I'm roughly getting into. If my ideas don’t fit there, then I gladly take that as a hint. The "Inform yourself!" doesn’t help me—I'm exactly trying to do that here. I actually want to spend a maximum of 700k to 800k—but more would be possible without having to restrict myself elsewhere. You’re welcome to judge that as a "what-does-the-world-cost attitude"—but that’s absolutely not what I mean. I actually don’t want to spend more than the mentioned amount. If you say I MUST do that with 160 sqm and a basement—then I can think about whether I want that—or make compromises.

And that someone implemented their first sketch—I still dare to doubt it—even if graph paper was used.

It is completely normal for costs to get out of control during the first serious planning phase. The major manufacturers also intentionally provoke this with their catalogs. And at first, you think "everything still fits" until you eventually do the exact calculations. Then it's no longer fun.

What would still be helpful for your plot is a drawing showing exactly where the street runs. I assume it is to the north? Is there any development on the neighboring plots? Also, mark the north arrow.

Otherwise, I agree with Yvonne. Anyone willing to spend €800,000 on a house should not just take a "ready-made" design and adapt it. The latter actually becomes really expensive. Furthermore, the big manufacturers have a habit of building houses that are allowed almost everywhere (which is logical) but are rarely adapted to specific requirements. And with the bushes, you already have a special requirement. By the way, none of them consider the terrain slope for you. That is the second problem with mass producers. They design the house as if it is floating and do not take the plot into account.

I absolutely don't feel like the costs are getting out of control. When I look at the usual suspects, I actually find catalog prices of 220-250k - where it’s clear that this can’t be enough. So I tried to research where the big difference might come from – with Viebrockhaus, quite a bit is included in the price that, with others, is added on top (what comes to mind are: building permits, statics, drawings, authorities, blower door test, soil survey, foundation slab (if no basement), earthworks (at least 2m around the house to 30 cm deep – of course disposal costs extra and the soil survey can cause additional costs), facing facade included, electric shutters, painter on the exterior, photovoltaic system (of course upgrades are possible here), ventilation system (yes, without basement – which of course costs extra) etc.)...

- Price list says 360k including all the aforementioned, heating, floors, standard electrical etc...
- I calculate 15k for change requests and sample selections (price list is here, worked through – fits more or less)
- 15k for electrical sample selection (price list is here)
- 160k plot
- 14k property purchase tax
- 100k basement
- 20k kitchen
- another 60k for terrace and garden
... that makes 744k – leaving another 56k for my actually set limit for unforeseen expenses. And my piggy bank is still well filled. Nothing threatens me here – except an expensive house.

If you really want to tell me that 800k is not sufficient for my project, then I have learned something. And I think I would then make cuts rather than expand the budget. As I already said, whether I am really willing to pay 100k (or even more) for the basement just to fulfill my dream of a home theater, I don’t know yet. I would have to watch a lot of movies before it pays off ;)

What would also be helpful for your plot is a drawing showing exactly where the street runs. I guess it’s to the north? Is there development on the neighboring plots? Also include a north arrow.

Otherwise, I agree with Yvonne. Anyone willing to spend 800,000€ on a house should not just take a “off the shelf” model and adapt it. The latter gets really expensive. Besides, the big companies also tend to build houses that are almost universally allowed (which makes sense) but are rarely adapted to special requirements. And with the shrubbery, you already have a special requirement. By the way, none of them will take into account the terrain step. That is the second problem with the mass producers. They plan the house floating and pay no attention to the property.

Yes, I have neighbors on the left and right sides... well, not yet, but then – it’s a new development area. The street is to the north. Below is a sketch with a north arrow.

How the street runs can also be seen in picture 1 of my initial post – that is a section from the development plan.

Here is still a picture from today of the property, looking south, the two sticks (if you can see them) roughly mark the beginning of a 9.50m wide house... just wanted to get a kind of "approximate feeling".

Whether that is enough, I can’t tell you, I’m not that far yet. I can only say that I have increased my budget twice and left out the basement. But it seems to be converging slowly. Typical upcharging traps in large format are, for example: - Heating is included but only air heating (as seen at Weberhaus, Schwörerhaus). Underfloor heating with heat pump booked and suddenly you’re 50,000€ poorer or something like that. - Floors are included but only carpet as standard. Upcharge for vinyl was around 140€/sqm at Weberhaus (!) and then it is only clicked together instead of glued. Your 15,000€ for change requests will go there. In the offer from the local main contractor, by the way, the floors cost 50-55€ per sqm. - Moving walls --> “free planning” = extra charge (by the way, then you end up with an architect’s house even though you only wanted to build one from the catalog) - Window adjustments? Whether this is the case at Viebrockhaus I can’t tell you. They are more active in northern Germany (that is everything north of Stuttgart). Maybe everything is fine, but I can only tell you that in the end we would have ended up at almost 370,000€ just for the house at Weberhaus, but that was about ~130sqm and had no smart home. And Weberhaus is not known as a cheap construction company. PS: The picture looks quite nice. I would still recommend not just placing any house on the plot but a specific house and the garage, the garden shed, etc. You don’t want to look directly at the garage wall through a window.
