What is the maximum cost my property can have?

how expensive is the price per 1sqm with you? 200€? 250€? you first have to get a feeling for it, so you can then see if you have something cheap or expensive. but you can forget about getting a 250€ plot for 150€ in a completely swept-clean market... at best! you get exactly what you pay for.

I find this project (house size, equipment) difficult to imagine with the given budget. Unfortunately, you did not specify where exactly you are building "50 km" around Cologne. Presumably more towards the Eifel than Düsseldorf. The land value map does show square meter prices below 50 EUR there, but I would already estimate the house you described at at least 300,000 EUR, probably more with the equipment. There will still be expensive details coming your way that you wouldn't have even dreamed of. And the craftsmen are likely to be expensive "50 km around Cologne" as well.

Ah ok, now I got it! Good idea! There are actually a few developer offers in the area, I will take a closer look and try to calculate from that perspective.

The land prices are at 350 in the immediate surroundings and go down to about 150 in more rural areas, which are still an option if the immediate environment fits. Basically, we are aware that for our budget we have to go a little further out (we both work in Cologne), but we would gladly do that for a "dream house." However, a dream house should, if possible, not have too many compromises, hence this thread. I just somehow don’t want to buy a plot that’s perfect only to realize afterward that our house can only be built within our budget with massive compromises. In that case, as I said, I would question the overall plan, ideally before the land is purchased. It’s not about +- 10-15K here, and also not all outdoor facilities need to be finished from the start; in the first step, for example, we don’t need a garage or carport. For some things, it’s enough if they are prepared (KNX, fireplace). But the almost unanimous opinion seems to be that it will still be very tight, which honestly surprises me and also makes me think a bit.

There are several individual plots that fit well distance-wise to Cologne, but usually, something else is off, or they are priced so outrageously high that it's actually not worth inquiring. Therefore, we are now waiting for new development areas, ideally marketed directly by the municipality, and will try our luck there. We would actually even prefer a new development area.

Another thing regarding the ancillary construction costs somehow got lost:

I have one more question, ancillary construction costs...
I consider 50K ancillary construction costs quite a lot and honestly always assumed that outdoor facilities (at least partly) or e.g., additional land costs are included in that. If not, then what exactly are the 50K for with a simple plot (without major earthworks) and without a basement? Wouldn’t 30K be more realistic?

Anyone have an opinion?

Best regards

A lot of reading that is worth it

I don’t know to what extent the tip about the developers was meant - it may be a rough guideline, but those who cannot properly read the offers will be overwhelmed by additional costs. But it’s all in the links

Additional construction costs: This cannot be answered so generally, especially since you do not yet know and cannot describe your property. Additional construction costs can increase immensely if, for example, you have to cover a long distance for development, if you first have to demolish old buildings or cut down and dispose of trees, if you have to work on the subsoil..., it depends on what your energy supplier charges for connection fees, which connections you even want (e.g., with/without gas), ... depending on the KFW standard, the base slab is different thickness and it has to be excavated deeper, with a basement there is even more. Depending on how high your groundwater is, water management may be necessary during construction. There are so many eventualities, you will only be able to estimate this once you have a specific property in mind. In any case, we are SIGNIFICANTLY above the 50 TEUR.

Ah ok, now I understand! Good idea! There are actually a few developer offers in the area, I will take a closer look and try to calculate from that perspective.

Calculate? – You shouldn’t take the offers as reference points from which you calculate something. Instead, go there, observe and perceive. Calibrate your budget-value-feeling against the market reality in your construction area. After visiting fewer than ten properties, you can answer for yourself what you get for your budget and whether it meets your value expectations.
