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since we are building, it should be energy efficient and we don’t want to use concepts that might soon be politically outdated or unsupported.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?

the long-held dream of self-fulfillment.

There is also something in between, namely a properly planned house that fits my needs. These vary from person to person. NOT planning it individually or taking care of it does not mean it will be cheaper; it usually becomes more expensive eventually.
We had a similar discussion here a few weeks ago, where the argument was roughly the same: I don’t need anything special, just a house, and I will handle the rest later...

At first, I see little reason to deviate from a standard floor plan with the living/dining room facing south and the kitchen in the corner.

...is THAT a standard floor plan? There are thousands of standard floor plans.
WilderSueden schrieb:

Even with completely free planning, we would probably end up with something quite close to such a floor plan.

That shows you don’t fully appreciate the work of an architect if their free design ends up being just another copy from the internet. You want to build relatively small, including a workshop, sauna, photovoltaic system, and more; every square meter matters when it’s poorly planned.
Without proper detailed planning, however it is done, there is a great risk that it will simply become more expensive without any gain in comfort; there are reasons why people spend a long time planning their house, and those reasons surely go beyond just the “self-fulfillment” you mentioned.

There are numerous standard floor plans available for your size and number of rooms. That is why I suggested how to create your room layout. You should draw it yourself. Besides, using dollhouse furniture can be misleading.

There is too much money involved to end up storing books under the attic because there is no bookshelf space, while you end up practicing dancing in the bedroom.

Ask 10 people here about their exact requirements, and you will get 10 different room sizes.

I’m not too worried about financing right now. The budget is roughly set, and there should be a bank willing to finance it on reasonable terms. Now the challenge is to align the wishes with the budget. There shouldn’t be any budget overruns even before construction starts 😉

The question then is whether a) your budget is roughly accurate, and b) if any bank is willing to offer you, as an individual, a loan of around 400,000€ (about $430,000) and, if so, whether the terms are reasonable. 😉
If your income is at least 4500€ (about $4800), it will probably work.

More like 120...

Once again, arbitrary decisions have eliminated the option for 130. Although 130 is still feasible. However, your room layout clearly calls for at least 140, especially with a two-story house in the space.

Large kitchen-living area

You definitely need more space on the ground floor than upstairs...

Turn your staircase out of the dirt zone

That thinking doesn’t make sense to me. No one is fixed on YOUR staircase or floor plan. It would make more sense if you first put together what will really shape your daily life—your floor plan—always keeping building code requirements in mind.

With a pre-designed house package, almost nothing is possible or customizable.

The current issue is that people looking at higher-priced homes are still only seeing standard offers.

My feeling is that buzzwords like KfW (energy standard), smart home, energy storage, etc., are coming too early in your plans and might lead you astray.

I also think these buzzwords are not only premature but are given higher priority than the house itself. But I admit: I haven’t followed the garden house thread. Did I miss anything?

You can only edit for 20 minutes

Is that new? I only get 10 minutes 🙁

For this plot, I see a gable roof house, so a bit more living space downstairs than upstairs. The gable can go either way, and the carports accordingly (placed together, you get more space) on the east or south side. Just try out some templates.
By the way, I also see a standard floor plan here, e.g., a half-landing staircase on the north side, an open-plan living area in an L-shape towards south and west, entrance on the east, gables facing east and west.
Or the house rotated 90 degrees with the entrance on the knee wall side...
If you drop the basement, then some details change, including all those buzzwords mentioned above.

Well..... then you probably only have the free version, while I regularly pay a subscription....... or I simply made a typo again

What do you mean by only? You still have to pay :p
