Bungalow or similar for €200,000 realistic?

Quite a bit has already been said, but you probably looked in the wrong places for hours. If you had read one or two threads here, you would know that your plan will probably not work that way.

From your €200,000, subtract €30,000. That’s the ancillary construction costs. That leaves €170,000 purely for the house without a basement and outdoor facilities. That would put you at €1,360 / sqm. That is the absolute bottom limit, and certainly not if you want turnkey construction and don’t want €5 carpet everywhere.
The budget also leaves no room for contingencies. Do you have a soil survey for your plot? There can be many hidden costs here.

Geothermal energy won’t work with your budget. As already mentioned, a bungalow is more expensive than a one-and-a-half-story house.

With prefab house companies, you will soon realize that subcontracting trades is not a particularly clever decision. Not to mention that the provider sets the rules here.
Mostly all or nothing. And whether you really save money? No idea. Certainly with painting and flooring work, but with screeding, plastering, etc...
The craftsmen from the prefab companies know the house’s quirks precisely and, as I experienced, work at a ridiculously high pace... They were like a whirlwind.
My private craftsmen all worked much slower, were significantly less reliable regarding deadlines, and in the end, did not deliver a better or worse result. With one difference: I had to do the acceptance alone. With a prefab house, there is often a site manager present who watches the guys closely. Not the optimal combination, but definitely better than me.
Moreover, you lose the warranty in many parts if you subcontract externally. And whether your cheap little craftsman can really be held responsible for damages, you have to trust.

My opinion: You have to add at least another €50,000 to handle the project properly. Maybe something will be left over in the end (Okay okay that was a joke, there never is anything left over ) You can then spend the money on furniture or a carport.

I have to disagree.
To the benchmark value of 1300-1500€/sqm given by Waldemar, additional construction overhead costs, outdoor facilities, possibly a basement, and costs for the geothermal heat pump would be added in your case. A bungalow is also somewhat more expensive than other house types because for the same living area more wall, floor, and roof area is required.

Musketier, it was only a question of whether it is possible or not. Surely it is possible! I could only give a rough benchmark. If it should be examined more precisely, one way or another the individual trades would have to be tendered in advance with exact material and manufacturer specifications, then it can be said precisely how much the construction project will cost.

But I am working on that.

Best regards, Waldemar

Thank you very much for the many, quick and detailed answers.

I have to disagree with that.
To the guideline value of 1300-1500€/sqm given by Waldemar, you would still have additional construction incidental costs, outdoor facilities, possibly a basement, and costs for the geothermal heat pump. A bungalow is also somewhat more expensive than other house types because the same living area requires more wall, floor, and roof surface.

Okay, I hadn’t considered that. The background was to design the house to be as barrier-free as possible. How much percent more would you roughly calculate for a bungalow of the same size?

Our house builder offers our house (1 1/2 stories, KfW-70, turnkey) from 140,000 already..

But then there are additional items like transport, foundation slab, expert reports, applications, construction site... etc..
And the "standard" range is also limited.

Including everything, plus selections, we have about 210,000 now, but also KfW-50 and a few extra changes.

How many sqm and which provider, if I may ask?

The most important question up front: do you have enough experience to manage such a project and how is your free time situation?

Thanks in advance for your detailed answer!
I assume I am slightly overestimating myself there. It’s not just about assigning contracts. You’re probably right.

Yes and no. It really depends on how old the connections are. If there are still clay pipes on the property, it may be that you have to apply for a completely new connection. Your utility provider can give you information on this.

Thanks for the info, I guess the connections are pretty old.

As mentioned, with solid construction and—regarding the pure house price—somewhat cheaper in Lower Saxony.

I am not so sure about the costs. Lower Saxony is correct, but it’s quite an expensive region.

With prefab house companies, you will soon notice that it is not a particularly clever decision to subcontract trades. Apart from the fact that the provider sets the rules here.

An interesting aspect - thanks.


Thanks again to everyone for the lively participation!
