ᐅ Realistic Construction Time for a Bungalow?

Well, bring it on!
(If there is a specific plot of land, you can also look into its zoning plan or similar documents).

Translation for non-experts:

Share information about your plot of land (municipality, parcel number, etc.), and 11ant would be happy to show you what is allowed there and what is not.

I would also say that you might be faster off working with a local masonry or carpentry general contractor (GC) who is well connected in the area and has a good relationship with the building authority / planning department. With a prefab house GC operating nationally or regionally, you are just one number among many. You will still run into the local master builder at the supermarket for years to come.

Depending on how the material situation develops, it could also be significantly more.

Rrrüschdüsch: the current bottleneck (and has been for several months) is the delivery times for heat pumps, for example; during that time, a dozen building shells have been erected (and dried out).

Note: without links! — for example, development plan number/name, municipality; any easements, status of the property...

Then it depends on whether you are building with a general contractor (GC) or a prefabricated house provider. The GC was much faster for us to implement; with all the prefabricated house providers, we wouldn’t have been able to build last year,

A prefabricated house provider is also a GC. By prefabricated house provider, you probably mean a GC who builds using timber frame construction.

Regarding the topic:
We are currently building with a GC using solid construction. About 14 months ago, we were in the same situation you are now. After 3 months, the GC and suitable floor plan were selected, followed by a 2-week cancellation period after signing the GC contract (nothing happened during that time). After another 2 months, the building permit application was ready, and the next 3 months were needed by the building authority for approval. Preparatory work such as excavation of the foundation pit and site leveling took 1 month. Since then, and for the following 10 months, the GC has been working. However, moving in is still not possible at that point. Flooring, walls, and ceilings have to be completed as DIY tasks beforehand. These are planned to take an additional 2 months.
Overall, we hope to reach about 22 months from the initial planning to moving in.

May I quickly add a question?
Similar situation: apart from the property with an existing structure (including the development plan), nothing else is in place yet.
Can I conclude from the above list that the first 9-10 months are mostly about handling formalities and planning before the excavator arrives for demolition?
Are there any seasonal weather conditions to consider? For example, a foundation slab in winter?

Answering this question in a general way is really difficult, especially if you are not yet in the actual planning phase. We had many discussions with different companies at the beginning and decided on one after about 4 months. We started talks in March 2021, and the first excavator began work in July 2022. Currently, the shell structure is up, the roof and windows are sealed, installations are completed, the electrician is finishing today, and early next year the interior plastering will start, followed by the screed. Roughly speaking, in our case, interior finishing began or was underway about two years after the initial talks.

However, we also planned everything completely individually and didn’t rush either the choice of company or the house design.
