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since we are building, it should be energy efficient and we don’t want to use concepts that might soon be politically outdated or unsupported.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

If the house is technically sound/well maintained/without backlog of repairs and not otherwise messed up (pick whichever applies), it will find a buyer. If the absence of a bathtub prevents a sale, it could just as well be another “missing” feature or different taste, etc.

This also shows how our individual lifestyles influence us. For me, the bathtub in the bathroom is like the stove in the kitchen. The latter is easier to retrofit, the former not so quickly.
My parents haven’t taken baths for 40 years, my husband and I on average twice a week.

Infrared cabin

That crossed our minds too. I wanted one last year; we both liked the idea—somehow the economy has to profit from us. … what happened? Nowhere did we find a suitable spot because of the sloped ceilings. Then I googled what the thing is actually good for (better late than never 😉) and realized that our bathtub does exactly that. Or the other way around: if you don’t have a bathtub and need warmth, install an infrared cabin for that. Just plan accordingly.
P.S. @WilderSueden My granddaughter is bathed almost every evening; it’s part of the bedtime routine. So much for baths only on Saturdays…!
Saturday bath routines for children, as my mother told me from her childhood days, were around 1950–1960 😉

Is there actually a floor plan after 30 pages of discussion?

A bathtub and infrared heating serve different purposes, especially when you’re not feeling well. I have both and wouldn’t want to do without either.

When you have a cold, nothing beats a soak in the bathtub. Except… without a cold, just get into the bathtub anyway. 😉

If you don’t want one, that’s fine. Still, having a bathtub is standard, and I assume that an apartment or house without one is harder to rent or sell than one with, no matter how “nice” it is. You don’t necessarily need two toilets in a house, but most often people have them anyway.

I understand, we will have both a bathtub and a sauna.

If someone doesn’t want one, that’s their choice. Still, it’s standard, and I assume that an apartment or house without a bathtub is harder to rent or sell than one with a bathtub, no matter how “nice” it is. You also don’t necessarily need two toilets in a house, yet most houses have them.
Are you just going in circles?
You claimed that a bathtub should be installed for the sake of SELLING THE HOUSE LATER!?!
If THAT ALONE—that is, selling the house in X years—is the reason, I wouldn’t install a bathtub just for that if I didn’t need one myself.
We have a bathtub, a second bathroom, and a guest toilet; I appreciate that, and the “best wife in the world” (Kishon) would not want it any other way.
The point was not about the pros or cons of a bathtub but about your incorrect blanket statement that a house without a bathtub has worse resale value (my own experience is exactly the opposite). There is no absolute—some people prefer baths, others showers. My stance is that I build according to what suits US, not future generations. I also don’t store shoe collections in the basement or attic just to sell them along with the house later. 😉
Once again, my response was to this statement:

In case you ever sell the house, it could negatively affect the value because for most people, a bathtub simply belongs.

I want to clarify: I would never want to do without a bathtub. Also, in case you ever decide to sell the house, it could reduce the value, since for most people a bathtub is simply expected, and installing one afterward is probably quite difficult.

I hope this settles the matter, as we are really just going around in circles now.
