Hello everyone,
after jumping straight into the basement discussion thread, I want to use this one as an introduction and idea-sharing thread. Some things might seem a bit chaotic at first, but that will surely clear up.

We are expecting our first child in February. Since two rooms are obviously too few for the long term, we need something larger. The housing market here in Konstanz is notoriously difficult, so we didn’t spend much time searching here. Thanks to Corona home office, we focused on areas a bit further away right from the start. Initially, we looked mostly at existing properties, but due to the poor condition of what’s on offer, we unexpectedly ended up deciding to build. We were actually lucky to get a plot in a new development area around Stockach-Pfullendorf. The site started being developed this week and will probably be buildable from summer onward.

Here are some key details:
- He/I am 33, work in the software industry, based in Konstanz, from a rural area
- She is 41, a teacher in the Hegau region, from a city that basically doesn’t exist
- One child on the way, no further children planned and unlikely due to her age
- Currently living in about 65sqm (700 sq ft) with 2.5 rooms in a lovely apartment building…
- Basically, we don’t want anything too fancy—no extensive smart home automation, no luxury mansion with marble and so on. Just something solid and nice. We are not building to fulfill a lifelong dream but to avoid renovating an old house worth half a million euros. Plain wallpaper texture and laminate flooring would be fine for us if the quality is good.
- Accordingly, we don’t mind using a “standard” floor plan from a prefabricated house builder or a typical model home.
- That said, since we are building, it should be energy efficient and we don’t want to use concepts that might soon be politically outdated or unsupported.
- Do-it-yourself work only to a limited extent, as we are neither professionals nor do we have relevant contacts. Also, the new house is a bit further away, so working on it in the evening is unlikely. A weekend of painting before moving in is no problem, and after moving in, doing the carport, terrace, and garden ourselves is also fine.
- The construction partner must be reliable.

Plot and financials:
- Plot roughly 700sqm (7,535 sq ft) at 98€ per sqm → 70,000€, fairly rectangular
- 120,000€ equity (with some reserve left)
- Financing and ownership entirely in my name (unmarried and no joint assets intended)
- Planned overall budget about 500,000€
- Target monthly payment 1,500€
- Accordingly, loan to be repaid in 25 years with that rate, with some extra repayments planned mid-term aiming for about 20 years total

Budget breakdown:
- Plot 70,000€
- Ancillary plot costs 5,000€
- Other construction-related fees 60,000€
- Basement 50,000€
- Kitchen 10,000€
- Driveway, carport, terrace as DIY 15,000€
-----
210,000€
Leaves about 290,000€ in the budget for the house itself, which is probably quite tight for what we have planned. The budget still needs to be adjusted with a buffer.

So far, our wishlist looks roughly like this:
- Not excessively large, more like 120–130sqm (1,290–1,400 sq ft)
- Efficient, modern house
- Photovoltaic system (possibly with battery storage)
- Underfloor heating with heat pump
- Home office for me on the ground floor (makes sense since I mostly work from home)
- Bedroom upstairs, one office for her that also serves as a guest room and reserve nursery
- Large open-plan kitchen/living area
- Basement
- Cistern
- Carport for two cars and one trailer

Our first contact about building was through an ad from the local Town & Country partner. The consultant was friendly, and the show house in Geisingen looked quite nice, but somehow it all felt a bit too conservative. Built according to the Energy Saving Ordinance 2016, standard gas heating. Sure, upgrades are possible, but I’m not sure if a heat pump makes sense under that regulation anymore. The fact that the show house had cracks in the plaster here and there isn’t exactly reassuring either. But the base price is lower. Current status: two meetings, visited the show house, haven’t requested the scope of services yet.

Then we looked a bit into prefab houses. Most offer KfW55 standard, which is closer to what we want and would be a good base for going to KfW40+ since a photovoltaic system is already planned (probably just with battery preparation though). Visited the park in Villingen-Schwenningen. Had a long chat with Schwabenhaus; the consultant seemed to want to downplay costs and was very keen to sell a ground-source heat pump with boreholes. The upgrade options for the promotional houses looked likely to increase costs significantly. Visited Heldhaus, liked it quite a lot but their cost outline overshoots the budget by roughly 100,000€.

Today we had an appointment with Schwörerhaus. The floor plan of one of their promotional houses fits pretty well. Basement plus KfW40+ seems somewhat challenging in combination. Otherwise, a generally good impression; the briefly reviewed scope of services doesn’t give the impression the house would be unpleasant to live in. Let’s see what the first offer will look like. I don’t get the feeling there’s much that could go wrong there.

Next week we have an appointment with Weberhaus. We found a floor plan we really like. The price is initially the highest, but their examples include KfW40+ standard and smart home automation upfront.

Our goal is to narrow down the number of companies we continue with to a maximum of two by Christmas and then decide on a construction partner early next year. In spring, the baby will take priority, not just house planning.

I’ve already posted some thoughts about the basement and possible basement substitutes. The insulation costs for the basement seem to fully consume the additional subsidies, so the photovoltaic battery would have to be paid out of pocket again. One idea on the drive back from the appointment was whether it makes sense to build the house initially to KfW55 standard without extra insulation. The difference in heating costs is relatively small. Then install just the conduit pipes for photovoltaics with battery preparation. A few years later, add a battery once prices drop. That would also likely bring the house closer to the planned budget than going for KfW40+.

These are my thoughts so far. Have I missed anything important?

Congratulations on the floor plans.
If you have your dream home with Town & Country or Weberhaus without many changes, then do as thousands before and after you have done.
If you now want to implement adjustments and special requests, the general contractor (GC) would be your person.
The fittings with the GC are often better because local craftsmen are involved and not pushed to the absolute limit.

So, fitting a child into about 12 sqm (129 sq ft) seems—let’s say—ambitious. Don’t forget: a child grows 🙂

Are you referring to the design for the local general contractor? If the balcony is removed, that would create a room of almost 20 sqm (215 sq ft). That should be enough then 😉

The only hairdryer in the household is mine, since I have the longer hair \m/
But I rarely use it myself.

@Nida35a
The Weberhaus floor plan is certainly not an absolute dream. The study feels a bit cramped, and the kitchen with its angles and a door right in the middle may look okay, but could cause complications during kitchen installation. The hallway feels somewhat narrow, and while it’s possible to fit a shower on the ground floor, the floor plan isn’t really designed for that. We also considered the Balance 200 model instead of the 100, which is a bit less boxy but otherwise quite similar. However, that would place the kitchen right in the middle of the room, which we don’t really like.

The Town & Country floor plan is better, and I think we could live well in it. The question mainly comes down to Town & Country as a company. My skepticism is partly influenced by this forum, but also by their construction description, which includes several points I’m not happy with, such as many “Product X or equivalent at the contractor’s discretion.” The big question is whether the builder’s idea of “equivalent” matches mine. I also haven’t forgotten the cracks in the show home in Geisingen. And in the end, there are still some tasks the builder won’t handle—like painting the roof overhang. I need to make a list of how many jobs and costs will really be added on top of the contract price and see what that means for the final cost.

Crazy, while I’m writing my floor plan post, you’re already going 1.5 pages off-topic again...

Yes, because you take so long (I recall several days). And this forum isn’t really the right place for floor plans anyway...

She thinks typical women’s things are silly, doesn’t wear makeup, no jewelry, and doesn’t do exfoliation either.

Great!
This is another point where I give up, because answers get ridiculed—by the person asking—while you were actually still trying to help with your replies.
Make sure you don’t forget to include typical “women’s things” like a washing machine connection or a cooker/stove when planning.

Certainly, I don’t have more than that either.

I said I would post it in a few days, and that's what I did. Writing something about each floor plan isn’t done in two minutes—you need to think it through while writing, so it naturally takes some time. Meanwhile, there were already one and a half pages about "alternative villas" and similar topics that hardly relate to our build.
I would post in the floor plan forum once we have chosen the company, realistically only if we build with the local general contractor. I don’t think Town & Country or Weberhaus allow major changes.

Here’s another point where I have to drop out because answers are being ridiculed, and it’s coming from the person asking the questions, even though I was still trying to be helpful with my responses.
Make sure you don’t accidentally forget to plan typical “women’s stuff” like washing machine connections or the stove.

That wasn’t meant in a negative way or to ridicule anything. But peelings are more of a typical “women’s thing” than a men’s, and since that doesn’t happen, there’s no need for a tub either. The other points are certainly valid. However, if I addressed all of them, we’d be debating for another 15 pages why I should install a bathtub. For us, having one is not a high priority.

The bay window in the basement will hopefully continue on the floor above, right??

Yes, it does. Upstairs, it’s part of the living room. Since this is a semi-detached house, we actually have two of them—one on the right and one on the left. And no matter what you think about them, we are not going to remove them. We really like these features.

Unfinished interior: three windows, bare walls, concrete floor, loose cables on the ceiling.
