I plan to have a prefabricated bungalow built next year in Lower Saxony, handling everything from planning to moving in. It should have approximately 150 m² (1,615 sq ft) of living space and, of course, be energy-efficient, including photovoltaic panels, electric storage, and geothermal heating. I already have a plot of land. What is a realistic timeframe for the entire process, including planning, building permit / planning permission, and the complete construction until moving in? Are there differences between providers?

Osnabruecker15 Dec 2022 15:31So, apart from an idea, nothing has been accomplished yet?
Then 2 years...
Look up the zoning or development plan, is a bungalow even permitted? Is geothermal heating allowed?
Find a general contractor, get to know them, request quotes, evaluate and compare. Their order books for next year are likely already quite full, so unless you are spending money freely, this step alone could take up to six months.
Then planning, permits (building permit / planning permission), ... depending on the designer, your special requirements, and the municipality, this could also take up to six months.
After that, you can calmly have your construction project completed and ready to move into within 8 months in 2024 (excluding landscaping and exterior work).
With luck and sufficient funds, you might have a shell structure by Christmas 2023, but that is wishful thinking given the current status.

motorradsilke15 Dec 2022 15:56We built a bungalow last year. From the initial planning stages to moving in, it took less than a year. However, we were lucky that our building authority only needed 6 weeks for processing. Others have waited 9 months.
So, I would recommend calling your local building authority first to ask about their processing times.
Then, it depends on whether you are working with a general contractor or a prefab home supplier. Using a general contractor was much faster for us. With all prefab home suppliers, we wouldn’t have been able to build last year, as they all had lead times of at least 9 months after approval.
So, it’s not something you can say in general. You need to look into it yourself and ask around.

Then two years... That won’t be enough: I don’t see the original poster starting from zero, but rather well before that point. First of all, you have to “unlearn” the misconception that the word “finished” in “prefabricated house” means it’s faster. Nothing goes faster here!

I want to have a bungalow built next year in Lower Saxony as a prefab, completely from planning to moving in. It should have about 150m² (1,615 sq ft) of living space and of course consume little energy, “Consuming little energy” and “bungalow” isn’t impossible, but it is somewhat contradictory at first. The less compact building shape has more envelope surface and uses more energy for heating, which cannot be fully compensated by a larger collector area.

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

How long is a realistic construction time including planning, permits (building permit / planning permission), and complete build until moving in? Are there differences between suppliers? Yes, there are huge differences in the boldness with which some suppliers advertise how fast you can reach your goal with them: while in one place you’re still waiting in the queue for your order to be processed, somewhere else you’re supposedly already celebrating the topping-out ceremony—“guaranteed,” of course. Believe it if you want. And that is just the first test for the reliability of fixed-price guarantees!
By the way, with this kind of nonsense, “solid” (masonry) house builders are absolutely on par with the “prefab” house providers. So, see above ;-)

WilderSueden15 Dec 2022 16:12Finding a provider and planning: at least 3 months
Preparing and obtaining the building permit / planning permission: 2 months (if using notification procedures or similar) – up to 6 months (slow building authority)
-- Only after this point will someone actually schedule you in. --
At least 10 months until moving in
A prefab house is assembled quickly, but the waiting time until the installation date can be long—sometimes very long. A neighbor two houses down received the building permit in November 2021, with the planned installation date at the end of February 2023. Not all providers have such a large backlog, and last year they likely sold significantly fewer new houses. With traditional construction, it takes a bit longer for the shell of the building to be completed, but they might start earlier. Still, I consider anything under 1.5 years extremely ambitious. Depending on how the material supply develops, it could also take considerably longer.
