Hello DaGoodness,
well, it all adds up. Let's assume a plot of land somewhere in the countryside for 80 euros per sqm.
Plot (600 sqm): 48,000 euros
Notary + property transfer tax: 4,000 euros (roughly)
Total plot: 52,000 euros
So you still have around 200,000 euros left for the house. Now let's take a smaller house with a total area of 150 sqm (for example without a basement) and calculate with a price per square meter of 1,200 euros (which is VERY cheap!), then we end up at 180,000 euros for the house. But that's far from everything. The full calculation would easily look like this:
Plot (600 sqm): 48,000 euros
Notary + property transfer tax: 4,000 euros (roughly)
Ready-to-move-in house (150 sqm): 180,000 euros
Earthworks: 15,000 euros
Architect: 2,000 euros
Construction power/water: 2,500 euros
Finished garage without electric drive with swing gate: 7,000 euros
Outdoor facilities: 10,000 euros (not much paved or done here!)
Connection work (Telekom, electricity, water): 2,500 euros
Permit procedure: 1,000 euros
Total: 272,000 euros
And to be honest: there is no buffer included yet, and some items were calculated rather at the lower limit! For the 180,000 euros at 1,200 euros/sqm you will hardly have a ready-to-move-in house, but a shell house. So you can easily budget another 10,000 euros for materials and 10,000 euros as a buffer! Also a tough year with many weekends, evenings and helpers on the construction site. We have not yet included new furniture, no fitted kitchen, no small stuff (curtains, lamps...) and for the floor coverings (parquet/tiles/laminate...), the number of sockets and light switches as well as the sanitary equipment, the price is also more on the cheapest side. Special requests such as a special type of wood, a glass railing, blinds or anthracite-colored window frames we forget or count another 10,000 euros again.
Conclusion: Even in the countryside with cheap land prices you very quickly end up at 350,000 euros for a SMALL house without many extras, where you will do a lot yourself. The 250,000 euros you mentioned I consider not feasible, as nice as it would be for me...
So why do so many people build? Quite simple!
1. They have some parents who give them a lot of money. I also know acquaintances who just got 150,000 euros for it! This is not an isolated case. And even our general contractor said that many parents and grandparents prefer to give their money to the child for the house rather than invest it in the current situation (crisis & interest rates).
2. They take the low interest rates as a basis and do not expect that in 10 or 15 years, renegotiations will happen with presumably higher rates!
3. They received a plot as a gift!
4. They do a lot themselves. Here too I have some acquaintances who have had a permanent construction site for 2 years, whose relationships and nerves are at their limits, and moving in is still a good year away. You can do it, but you have to be the kind of person for a 3-year construction site!
I don’t want to discourage you. But take an architect and give him the order to plan a house for your budget including all additional costs (see above, although I don’t claim this list is complete... for example I forgot the structural engineer and the surveyor!!!).
