Hello everyone,
I’ll briefly describe our situation. We have reserved a plot of land for a single-family house. We would like to build a solid (whether Liapor or another type of "masonry," we are not really sure) structure on it. The plot is flat and square, measuring 417 m² (4490 sq ft).
We are allowed to build 2 full stories with SD, PD, FD, although only one SD is an option (maximum ridge height 9.5 m (31 ft), maximum wall height 6.10 m (20 ft)).
So far, we have received offers ranging from €3500/m² (local large contractor) to €2800/m² from, for example, Fingerhaus (probably excluded due to timber frame).
Now to our dream house:
- KfW 55 standard
- solid construction method (type not clear, will depend on budget; do Liapor and “masonry stone-on-stone” not differ much in cost?)
- 140 m² (1507 sq ft) living area
- 1.5 stories with a “high” knee wall
- basement (utility cellar, which can be finished later, connections for heating and electricity installed)
- house dimensions (determined by room requirements? 11 x 9 m (36 x 30 ft)? 11 x 10 m (36 x 33 ft)? Building area ratio of 0.4 is sufficient)
- including photovoltaic system with battery storage
- turnkey delivery
- Basement: technical room + laundry (15 m² (161 sq ft)) + large hobby room (approx. 30 m² (323 sq ft)) + fitness room (15 m² (161 sq ft)) + cellar (10 m² (108 sq ft)?) + hallway / stairs (? m²) = 70 m² (753 sq ft) + x
- Ground floor: living & dining area + kitchen (approx. 45 m² (484 sq ft)) + pantry (3 m² (32 sq ft)?) + guest room (>12 m² (129 sq ft)) + shower bathroom (4 m² (43 sq ft)?) + hallway / stairs (? m²) = 64 m² (689 sq ft) + x
- Upper floor: child 1 (16 m² (172 sq ft)) + child 2 (16 m² (172 sq ft)) + master bedroom + dressing room (20 m² (215 sq ft)) + bathroom (14 m² (151 sq ft)) + hallway + stairs (? m²) = 66 m² (710 sq ft) + x
Calculating room and floor area requirements (without the unknown x for stairs and hallways/entrance) we come to approximately 130 m² (1399 sq ft).
Our specific questions are,
a) Which “solid construction” companies do you generally recommend in the Tübingen area?
b) How much area should roughly be allowed for hallways and entrance / stairs? Yes, it depends on the floor plan, but we would like to estimate the total space requirements.
c) What rough price range should we expect in €/m² (living area) + €/m² (basement) for Liapor or other masonry? We do not want to consider additional costs like kitchen and garage here, but they are naturally included in the overall budget.
We hope you can help us. Please feel free to ask questions—I’ll respond promptly.
Have a nice evening!

I’ll start "backwards" as you said:
That your project will be considered "feasible" has been confirmed here several times without any objections. So the house is definitely possible, and the uncertainty about whether there will be enough space for the small decorative frames around the light switches cannot be resolved in advance.
Looking at dream house pictures online is only slightly risky in your case, as the plot is flat and not worryingly small, so not many ideas will clash with the reality of what’s possible. The "setting the course" is the appropriate feasibility check—you know how it works and what it costs. Right now you can still have the result before the summer break; your hesitation is the only brake.
Space-consuming in terms of building volume, or in terms of extra costs like electric window openers, glass shower doors, and a front door with custom polyphonic doorbell tones to distinguish between mother-in-law and delivery person?
Or do you fear that you won’t be able to afford the house anymore because the architect’s fees have already eaten up your budget? If so, I’d say that paying for phases 1 to 3 (concept design to final design) to a basic floor plan drafter would be the safest way to learn this lesson.

If a feasibility comes out of this, I’m more relaxed and I think the implementation path will become clear.

We’re going through floor plans on Pinterest, catalogs, and so forth, but what we really need to do next is check if the budget can make the dream happen, or if it will remain a dream that’s too expensive. That step seems most obvious to clarify.

No, we don’t want that. On the other hand, we do have a tight budget and quite space-consuming ideas.

I'll start "backwards" (in the order of your words):
That your project is considered "feasible" has been confirmed here multiple times without any opposing opinions. We basically see feasibility as well; it’s more about sticking to our desired floor plan concept and the costs --> an architect is necessary to plan efficiently in terms of space and realistically.

You know how it works and what it costs. Currently, you can still have the result before the summer holidays; your hesitation is "the only brake." The notary appointment is scheduled for June, and the soil survey is set for next week. Finding an architect (I’m only doing gendering once here) is the next step. At the same time, we have appointments with companies like HEFA, Hauser, and others to get to know them and get a feel for who they are, how they build, what they offer, etc. Purely for getting acquainted.

Volume in terms of building mass Yes, exactly—what amount of square meters is required for the desired floor plan? 135sqm (1450 sqft)? 150sqm (1615 sqft)? There are, as I assume, rules, standards, DIN regulations, etc., considerations of structural engineering, and so on, which result in a floor plan design.
Another question:
Can you basically recommend a "home building fair"? I guess it won’t hurt, although as a layperson it might also be risky?
If yes, which ones?
In parallel, we have revised and better categorized the "additional costs" and roughly when they will occur. Immediate = before construction starts. I will move this discussion to another thread but am happy to continue it here, so I’m including it here.
Green is very certain, red are estimates.

I assume there are rules, standards, building codes, etc. including structural considerations that lead to a floor plan design. Another question: can you generally recommend a "home building fair"? I guess it can’t hurt, but could it be risky for a layperson? You can’t predict down to the exact square meter when a house will “feel right,” and there’s no magic formula for that. I have already mentioned a multi-part rule several times: 1. start floor plan design more from a numerical/calculative approach rather than a visual one, 2. when switching to the visual phase, begin with the more complex floor (usually the upper floor). Inspiration floor plans are only transferable as well as your room program matches: if you need one more room, you have to choose a correspondingly smaller template, and transposing between different house types (for example, between a one-and-a-half-story and a villa design) regularly leads to unsatisfactory results. Home exhibitions or fairs only become risky if you haven’t sufficiently repeated the mantra “we sign nothing” beforehand.

Teimo198810 Apr 2025 16:42Based on experience, your estimated costs for the building permit / planning permission and structural engineering seem too low, at least if these are done by an architect and structural engineer. The costs for connecting utilities might be accurate or slightly underestimated.
Your budget for access paths, parking spaces, and the terrace is far too low. Even if you get a digger for free, that won’t be sufficient.
