Prefabricated house provider with electrical installation as own work

Here, only the loss of the complete(!) warranty etc. was argued.

Which is factually absolutely correct:

I looked at it from the perspective of solid construction and mistakenly equated it with timber frame construction.

In solid construction, you can chase grooves because no vapor barrier has to go into the wall.

However, you can also go the route of ordering appropriate empty conduits (probably at the same cost as if all the cables were pulled according to your plan), or concentrate your electrical own work on planning and control wiring.

We built with Büdenbender [...] In the equipment consultation, I provided all necessary information (sockets, outlets, etc.).

Now, Büdenbender is also a Michelin-starred restaurant, which is probably not really comparable to Okal Haus and Streif Haus.

We are torn. Ideally, we would like to build with an architect, but the costs are a bit daunting. Although it is said that architects secure better offers through tendering, the initial calculations are significantly higher. Therefore, we are considering switching to a prefabricated house provider.

In the meantime, we have also received information that the electrical installation can be done by oneself. One presents the electrical plan during the sampling, and then it is prepared. Whether the cables are pulled directly or only empty conduits, I am not exactly sure. At least it’s an option, but I am not entirely convinced yet.

Nun ist Büdenbender allerdings auch ein Sternerestaurant, mit Okal Haus und Streif Haus wohl eher nicht zu vergleichen

How would you assess Okal Haus and Streif Haus, and which providers are qualitatively above Okal Haus and what makes those providers "better"? I actually thought that Okal Haus was positioned rather high.

Therefore, we are considering switching to a prefabricated house provider.

An indestructible myth is that prefabricated house providers are generally "safer" for tight budgets. The real core is at best that prefabricated house providers have more experience with the concept of the "shell house." Budget overruns occur on all paths, only the reasons lie elsewhere: in solid construction more due to price increases during the construction period and less precisely determined quantities, in prefabricated construction more due to upgradings.

Whether the cables are pulled directly or just conduit pipes, I don't know exactly.

Conduit pipes primarily unfold their advantage when the installation is later expanded.

In general, pulling wires is intellectually apprentice work and thus does not have much wage cost potential. Wiring is somewhat more demanding.

I would advise you to reconsider the savings concept: high standard (home automation) and the naive idea of making oneself "useful" in a way that impacts the budget versus less standard; and with a prefabricated house, you cannot do the masonry yourself – but you can with the kit house.

Who overtakes on the shoulder might turn onto the wrong track

Well, the budget is always tight We just want to get the best out of the budget. So far, it looks on paper as if a prefab house, despite a generous sample buffer, turns out to be cheaper.

High standard and lower standard is difficult to compare. What prefab house providers sell as Smart Home, I don’t see as Smart Home. It’s more like a remote control and no one would call an old tube TV smart just because it has a remote control I can do the planning, the connection, the parameterization, and the programming myself and why shouldn’t I do it if I can? For example, I would never do masonry myself

As I said: I don't see that prefabricated houses become cheaper or just stay better within budget. When pulling wires, you can feel like you are very active, but those are low-paid hours. I would always divide a control system so that you do the programming yourself and the interface is the outlet. That means you specify at which point how many wires coming from where should come out of the wall again. I don't see the profit in money, but (significantly or only) in the fact that you are decades ahead of the house manufacturers in imagining applications. That means that if you do it yourself, you don't have to wait until 2040 for them to catch up.

Ah ok, now I understand what you mean. Thanks.
