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!

And what stops you from clarifying this BEFOREHAND, so you can plan it properly into your build?
Friends don’t have to help with building a house, who says that or even assumes it? I don’t. Due to the distance from family and friends, I also had very little support with DIY tasks. I never assumed otherwise.
This “clarify beforehand” can easily mean a year or more between agreeing with a buddy before signing the contract and the actual DIY work. Especially since the date for the DIY work can’t be predicted. In the meantime, a lot can change in the lives of those helping. Suddenly, a vacation comes up, a new partner, a child, a new job, and so on. I’m not saying it can’t work, and that maybe another buddy can step in. But not everyone has a large circle of friends ready to jump in.
I’ve been following this forum for over 12 years and have often read that much of the work ends up being done alone because helpers don’t have time every weekend after all.

Vrumfondel8 Apr 2025 14:53I don’t think anyone needs to (or will) try to convince others of their perspective here.
Both experiences exist and are valid – which one is more common in reality cannot be settled in this discussion.
For the original poster and all other interested readers, it has likely been helpful that two very different viewpoints were presented with conviction and in detail. Based on that, each person must assess their own circle of friends or acquaintances. If you are honest with yourself and the situation, and conclude, “Yes, I can do this with my friends,” then that is the way to proceed. However, if it then doesn’t work out, you can’t say “I wouldn’t have thought that before” afterwards—you’ll have to live with the outcome.

This "clarify in advance" can potentially mean a year or more between the agreement with a friend before signing the contract and the actual self-performance.That’s true. A long lead time can potentially be challenging. Therefore, some practical judgment and flexibility, as well as clear communication, are required during the planning.Practical judgment: When you define specific work packages that can be completed in one day, one evening, or one weekend, more precise commitments are possible. This helps the helper know what they are getting into.
Flexibility: This relates to the schedule and the order of the tasks. If a date doesn’t work out, find another one.
Communication: The better the helpers understand the construction progress and the possible time frame for their involvement, the fewer surprises there will be—for both the helpers and yourself. It is helpful to explain some of the reasons behind the sequence of the tasks, so not only the "what," but also the "why" and "what this means" are addressed.
In addition to the environment, project management skills are always essential if it is to work. People also create different “realities” of the situation they face.

Teimo19888 Apr 2025 15:54Regarding helpers, I’m familiar with all kinds of situations. For example, our neighbors are building their house entirely by themselves, with only the plastering work contracted out. During the masonry work, there are about 10 family members on the construction site, taking time off from their annual leave for this. In previous years, they also helped out on other construction sites or for other family members. And so it goes in rotation. This saves a lot of money but also requires a huge amount of time and effort, on all sites, not just one’s own.
I think you generally know how much you have helped others, so you have a good idea of how much help to expect in return.

is, but not in the decision-making processOne question: How can I best find an independent architect who charges a flat fee, especially when comparing options? Also, what should I consider regarding their area of expertise, such as regulations and standards, particularly for the specific building area? So far, I only know the platform a better. I have also tried researching on YouTube or by searching online. I would appreciate help with this decision-making process.N

One question, how do I best find an available architect who charges a fixed fee? Call and ask.

What is his/her area of expertise, e.g., building codes and standards in the specific construction area? They don’t need to know the specific area in advance—that’s what they’ve studied for. You can ask what types of houses they specialize in and request to see examples of their work (references).
