ᐅ House Construction: Prefabricated House or Solid (Masonry) House? Experiences and Price Range

Hello everyone,

We have been looking into the topic of building a house for several months now. Unfortunately, we are quite new to this field and are not familiar with all the details. Of course, we have read a lot and searched online, but you often come across different information, especially older and not so up-to-date sources.

We have a plot of land in the city that we are considering. It is about 830 m2 (0.2 acres) including partial utility connections. The cost of the plot is 130,000 euros, and of course, you need to add property transfer tax, notary fees, and land registry costs (anything else we might be forgetting?). Since the plot only has partial utility connections, all the connections are apparently in front of the street because the land was subdivided. So, naturally, there will be additional development costs; we estimate around 10,000 euros. Overall, we would be looking at about 150,000 euros for the land, which is fine so far.

Now comes the house. We are leaning more towards a prefab house since a custom architect-designed home requires a lot of work, right? I have, of course, checked out several providers, and the prices are always quite attractive. We are assuming a 150 m2 (1,615 square feet) prefab house, which shows a price of 380,000 euros including all the services the provider offers. This is assuming a turnkey package. What other costs should we expect? I assume garage and landscaping are obvious extras, but are there other expenses we should factor in? Perhaps someone here has experience with this kind of build and could help us.

We would like to have a rough estimate to see if many additional costs might come up since, otherwise, the total would exceed 600,000 euros for a 150 m2 prefab house, which seems a bit unclear to me.

Thanks in advance to everyone!
