Personal price limit for house including fixtures: 350,000-400,000 (plot already owned)
Preferred heating system: district heating

The current draft was created based on various show homes and manufacturer catalogs. What I liked well in the show homes has been incorporated into the floor plan. For example, the bathroom design in a T-shape; shower and toilet are hidden left and right behind the T. Unfortunately, my current drawing tool does not allow furnishing. I have to print the plans and add furniture layouts by hand. A furnished floor plan will follow.

I think the floor plan shows the intended rooms and the desired space requirements.

I hope this now provides a better working basis!

Your budget is a bit tight. Something will have to go.
With a child, there is less time for hobbies.
The idea that babies only sleep in the beginning is a myth.

Really consider whether you might want to have an above-ground room. Daylight is especially nice at a workbench.

What would you consider a necessary minimum budget for 160 sqm (1,722 sq ft) including a basement? On what assumptions are your budget estimates based?

Hmm, I don’t quite understand that. It’s easy to say that 400k € is not enough, but then I’m not allowed to be given a rough estimate of what is actually needed?!

A basement is almost a must-have since I have hobbies that require a lot of space. Brewing equipment, fishing gear, woodworking shop, and maybe soon even a game meat storage room... I would have to build much bigger to manage without a basement.
[From one preference discussion about open space vs. no open space straight into the basement vs. no basement debate. I hope we can get back to the main topic now?]

I have a quote for a log house with 160 sqm (1720 sq ft) for around €270,000 (including electrical and heating). That would leave €130,000 for additional construction costs and the basement if I assume a budget of €400,000.

Hobbies are of course a reason, but for my woodworking shop I made sure to have daylight for a nice atmosphere. Regarding the mentioned €270k for a 160 sqm (1720 sq ft) house – what stage of completion is that? Or how does the provider call it? Sounds like a lot of work done by yourself.

Concerning the cost estimate: for a reasonably nice single-family house (turnkey) I would expect to budget €2,500–3,000 per square meter of living space in Bavaria.

Move-in ready with some own work can be done for under 2,500. However, you’ll need to specify everything with a very tight budget.
Even if you manage to hit the magic 2,000 mark,
the cost for 160 m² (1,725 sq ft) already comes to 320,000 plus basement plus garage plus additional construction costs.
Don’t ask about the landscaping costs. Even if you do it all yourself, 10,000 won’t get you very far. Your plot is not exactly small.

How do we judge this?
We are all further along in the building process than you. We know how quickly another 1,000 can disappear.
We’ve been active here for a longer time and read threads like these, among others:

https://www.hausbau-forum.de/threads/warum-ein-Hausbau-fast-immer-teurer-kommt-als-kalkuliert.16237/

https://www.hausbau-forum.de/threads/liste-der-anfallenden-Baunebenkosten-bauseits-teurer.9737/

There was another one somewhere:
Why was additional financing needed? Or something like that.

Then also these:
https://www.hausbau-forum.de/threads/Bauvorhaben-Budget-gesprengt.28751/

https://www.hausbau-forum.de/threads/baukostenentwicklung-noch-normal.28743/

Here, everyone compromised because the wish/dream could not be realized within the budget.
For us, the house from the foundation slab accounted for about two-thirds of the costs.
Foundation slab, garage, landscaping are real heavy hitters, then there are also many small items:
road closure, construction power supply, relocating the light pole, and so on.

You can see that open spaces or galleries are not really appreciated here.

My point was only about the dogma that a gallery = bad or only feasible from 250 sqm (about 2,700 sq ft) upwards.

That’s not true. I have also criticized the open space concept, but I have one myself. First plan the necessary rooms, then the nice-to-haves! And yes, it’s very noisy. I already knew that from my parents’ house, but since we don’t have children living with us, the adults naturally take care to be considerate. In a family of four, there are certainly more contrasts in daily routines.

I would gladly develop this new design further in the forum as soon as I have it.

We are looking forward to hearing from you. Hardly anyone here gets left hanging if there is something to discuss.

Maybe as an alternative, a small extension that is open up to the roof could create the desired feeling of open space. I just really like it when rooms are open up to the roof slope.

You can simply open the rooms under the roof upwards. The additional cost isn’t too high.

You’re planning two children’s rooms and building on a plot over 1,000 sqm (about 12,000 sq ft). I can imagine you might not have time for one or more hobbies anymore. Garden and related tasks already take up several hours a week. Plus the children, of course. Just a thought.

If I were you, I would plan a nice wooden extension or garden shed. Start setting aside money for it now. All the basement offers you’ve seen are generally for an empty, unfinished basement without stairs or flooring.

Which level of finish is included? Also sanitary fixtures? Toilet and shower? You should also budget another €20,000–40,000 for equipment like controlled ventilation, sockets, and floor coverings. And then there’s the basement (finishing) as well.
