Estimate of construction costs for a single-family house in the Tübingen area

If the kids ever want to use it as a hobby room or I myself for a small DIY area. Workbench etc. But honestly, you end up getting carried away with cool things you could do at some point.. the roadmap that distinguishes between must-haves and nice-to-haves is important first. Our requirements specification so to speak.
We want a house that:
- an open kitchen with pantry
- it is important to us that the living area is as open as possible to keep an eye on the kids and to offer as much freedom as possible.

- a living area that is long enough to accommodate a table for approx. 12-14 people (max. 1 - 2 times a year)
- a guest room on the ground floor, which can be set up as a bedroom in old age, a normal 180x200 bed and a “classic Pax”.

Workbench etc. But honestly, you end up getting carried away with cool things you could do at some point.. the roadmap that distinguishes between must-haves and nice-to-haves is important first. Our requirements specification so to speak.
We want a house that:

- Garden oriented more in a way that you can enjoy the sun in the evening, no midday sun.

- Parking facilities are important because there are no parking spaces on the street (3 cars must fit)

- an open kitchen with pantry with plenty of storage space (small freezer, beverage shelves and co.)

- it is important to us that the living area is as open as possible to keep an eye on the kids and conveys a strong sense of freedom

- a living-dining area, which is long enough to accommodate a table for approx. 16 people (about 5 times a year)

- a guest room on the ground floor, which can be set up as a bedroom in old age, a normal 180x200 bed and a “classic Pax”. Initially serves as a home office or when grandma and grandpa come on weekends and would sleep here.

- a shower bathroom on the ground floor, which is easy to enter but does not have to be barrier-free. Ideally close to the guest room.

- the size of the children's rooms is important to us so they can also pursue their hobbies, and both must be the same size.

- bedroom size is not a priority and can benefit the children. However, parents should be spatially separate from child 1 and 2.

- a large walk-in closet is not necessary, nice to have, but then with a window

- no floor-to-ceiling windows in the bedrooms (heat protection)

- the staircase should not be too steep; a landing in between would be important, I am clumsy and I like pictures and such in the stairwell.

- acoustic separation between living room and upper floor is absolutely necessary,
So the stairwell is closed off by a door to the living area.

- the dirty area must be completely separated from normal walkways.

- the bathroom upstairs should have a T shower WC combo and a skylight / if 2, a VG above the bathtub (bathing is important to us)
- niche in the hallway for towels and such.

- I would like to have an area somewhere where I can practice my boxing sport (punching bag, a weight bench, a bit of space for jump rope. Should not bother anyone acoustically - can gladly be behind the garage or something else?

- storage space for bicycles, Bobby cars, suitcases and all the bulky stuff you have with maximally 2 children. But we don’t want to carry that stuff upstairs into the attic.

- little stairs running for laundry washing; better yet, laundry basket and washing machine directly in the bathroom.

so these were the basic things important to us:

I’m just not sure how to proceed after this list. Visit model homes? Visit parks? Get a feeling for what we imagine and what reality is?
Would we find ourselves in a catalog house directly or not, what then?

Either way, go to the architect who creates a preliminary draft for us with which we go to the individual Heinz von Heiden of this world?

I think that starting from the “must-have” things, a normal catalog house will come out. With minor compromises here and there.

actually haven’t seen anything live yet?

No park no model homes, we were unexpectedly assigned the plot 6 days ago - we never ever expected that.. maybe you notice the surprise in our questions

The principle is meant, right? I will inquire, I did not find any inspection chamber on the property itself - but I wouldn’t expect that either. In this specific case, the backflow level is almost the same as the current level. That means the two water columns would be almost the same height. Water column in the sewer

Gracious goddess, no, you have thoroughly misunderstood and mixed that up. The principle of communicating vessels applies between the elevated tank and the extraction points of the connection participants of the water supply and ensures the water pressure at the tap. So in the supply of the “white” water, one could analogously call it “upstream water” relative to wastewater. Where the next inspection chamber is (and whether it is on your property) is a completely different matter. What you found at the waterworks is a schematic drawing for East Frisian blondes. The green columns shown would occur in a malfunction case if the sewer was maximally clogged. The backflow level should always nicely remain theoretical. If the case as drawn seriously occurred, the residents’ slurry would flood the street and a manhole climber would be a diver. If the house wastewater pipes were filled like in the drawing, the house would have flatulence. Also, the sink does not discharge black water but gray water. This is really just a highly simplified schematic drawing in which the cows are purple.

I have now read your basement rules, but I don’t understand the first one already. I guess it has to do with how hilly the property is. The hillier, the more expensive and senseless the basement? No idea.

Can it really be misunderstood that roughly? – then I will clarify it directly at the source in the next few days. On the contrary: the flatter the property (especially under the house footprint), the more worth reconsidering the basement, because the property (although no veto, but) gives a clear negative vote.

I find the schedule very good – we will do our homework – the schedule sounds like creating a requirements specification or a specification sheet – that makes much more sense than just rushing off to floor plans and what does it cost.

Conceptual approach instead of blindly rushing to floor plans is always the smarter choice, but the schedule is really just a chronological itinerary preview with explanations and recommendations. The (complete) basic series represents the normal path, and the (still to be extended) “Reloaded” series follows the reader’s wish that I also illuminate deviations or variations. The erotic fixation of laypeople on floor plans I probably won’t be able to cure.

For big parties there are inns, equally sized rooms only make sense with identical twins, I see a shower on the ground floor depending on the dog’s love of dirt, and sunlight in the dressing room causes dust to stir up.

I’m just unclear how it continues after this list. Visiting model houses? Visiting parks? Getting a feel for what we imagine and what is reality? Would we find ourselves directly in a catalog house or not, what then? Either way to the architect who draws up a preliminary draft with which we go to the individual Heinz von Heiden of this world?

“Visit”, consciously walk through and sketch your own existing apartment, bring a tape measure, mark bottlenecks, note everyday dwelling annoyances, then you have a picture of reality and where you urgently want to change it. A catalog house is with increasing similarity to the average family and on a flat plot very likely already essentially a tailored suit, yes. Either way, commissioning a freelance architect for module A (and more in the first tranche not yet) is the logical conclusion if you have read and understood my schedule. On my “Services” page, you will also find the initial decision-making. Gabriele’s favorite Heinz has so far never been among the candidates I requested; the owner-managed, regionally focused builder (shell construction as well as turnkey) is, according to experience, the best choice. Don’t forget: first make the initial decision during the dough resting phase, whose insights then flow into service phase 3 or other further ripening to the design, not in one step directly to the general contractor. Getting drunk on ideas in model home exhibitions increases the risk of a McMansion hell.

Can it really be misunderstood that roughly? - then I will directly address it in the next few days

No, I just don’t get it – I keep stumbling over missing vocabulary. The glossary helps then.

For big celebrations there are inns, of equal size

That’s the topic, if we only celebrate one birthday we are very quickly at 12 people and it is important to us that we are at home and in the garden with the family.

similar to the average family

Is there a definition of this average family? We are currently 2 adults, 1 child with the wish for 2K. But it’s about needs. I wanted to leave a thank you aside from the discussion again, you really open eyes!

"visit" your own existing apartment, consciously walk through and sketch it out, take a meter stick, mark bottlenecks, write down everyday housing annoyance cases, then you have the idea of reality and where you want to urgently change it and how.

That has flowed into our wish list – in addition, there are wishes that one has had all one’s life.

This is the topic, if we only celebrate one birthday, we are quickly at 12 people and it's important to us that we are with the family at home and in the garden.

Then you do it like everyone else (you haven’t invented celebrating now): put up beer benches and standing tables, set up a buffet, equip the dining table with folding chairs and everyone finds their place, wherever. In a pinch, the place at the kitchen island standing up will do.

But we don’t want to carry that stuff up the stairs into the attic.

So, 10 sqm more storage space instead of walking up a staircase once?

(3 cars need to find space)

You have a 417 sqm plot.. You haven’t won the lottery..

I'll give you some advice: look at other houses.
Draw the plot with the building boundaries, mark parking spaces and terrace. Of course, also the house.
If you put yourself on a list saying you’re interested in a plot, you should know what is possible: with the money, but also with the plot.

Would we find ourselves in a catalog house or not, what then?

If you look at >180 sqm, yes.
But I think you should revise your list a bit.

Can this really be misunderstood so roughly?

Yes! I understand "your rules," but I also know your complicated language. For others, it might be that they give up the effort to read the texts. You have to speak for the receiver and not for yourself.

know what is possible: with the money, but also with the property.

That was 4 months ago at 3% interest, now we are at 4.3, that already ruins a project or not. Of course we looked at what was possible back then, but today it is different.

That was 4 months ago at 3% interest, now we are at 4.3, that already ruins a project

No, that shrinks a project to a normal size. If it ruins the project, it was already too expensive before.
