How do you search for a suitable property developer?

So you don’t have a property and are now looking for someone who can offer you both from a single source?

First, take a look at what the differences are between [Bauträger], [Generalunternehmer], [Generalübernehmer], [Fertighausanbieter], [Architekt]. Then you will already know what you are looking for. And as [toxicmolotow] already wrote, the land issue is essential at first.

Hello,

either our supervisor separates from his company (or vice versa, unfortunately we don't know), or the house suddenly cannot be converted according to our needs (6 living or working rooms) and and and

You are looking for the jack of all trades

You must first decide what you want; the argument "I just want a house" is a poor guide! Who is your supervisor? With what qualification? With what assignment from you? Perhaps a financer?

A developer sells you a plot of land including the new construction of a single-family house (single-family house) from a single source; a general contractor or taker builds on your plot of land (meaning you find the plot of land yourself; which, btw, has many advantages), an architect "only" designs your house (for which a plot of land is also required). A solid house is conventionally built stone by stone (or also assembled with prefabricated parts); with a prefabricated house the shell is erected within 3 days in different production stages (depending on provider/order value), but the lead time is significantly longer. There is also the option to purchase an existing property, which requires the expert support of a surveyor beforehand and a capable architect (execution plans, tendering) during the conversion work. It is also recommended to commission experts with monitoring/construction management.

Above all, your budget comes first and should be determined - at least approximately - beforehand. Only when you are clear about all these points can you decide what you actually want!

And keeping it brief is often a good thing, but in a forum like this it is counterproductive

But if you don't know the terminology, then that's the first thing you should take care of, because depending on the terminology, it is simply misunderstood here and wrong advice is given.

In addition: A GU/GÜ offers a piece of a house without land, a developer offers a house with land.

That is all basic knowledge.

And you talk about "what is financially feasible" and in the same breath you talk about "what I want must be offered." Of course you are right there, but special requests cost extra money. That's how it is in the market economy.

In part, I have to admit you are right.

We are then looking for a general contractor/general planner because we already have the property; it just needs to be co-financed.
It was not about what is financially feasible, but what is cheaper for us: a lower level of development plus materials and time, or a higher level of development right away.

There are no special requests in the sense that we want something extremely extravagant, but small redesigns, for example:

- turn a 45 sqm living room into a 15 sqm office and 30 sqm living room (an extra door and drywall)
- turn 3 rooms of approximately 20-25 sqm each on the upper floor into 4 smaller rooms and move the bathroom to another location on the upper floor (an extra door and drywall and relocation of electrical, water, and drainage lines for the bathroom)

As a trained bricklayer and electrician and with a plumber in the family, I can already judge quite well that all this is no rocket science and everything is feasible and not really associated with high costs!!!!!

Well, a [GÜ] offers you a complete house, possibly only finished up to a certain point. What comes after that is then your business.

It can hardly be judged across the board. For example, what do you pay with the [GÜ] for "Heating complete including installation" and what do you pay for "Material only"... depending on the trade, it may well be that with all the stress you would have ended up cheaper with installation.

And believe me on this: everyone you mentioned probably has a 40-hour week with normal work. So doing it yourself will prolong the whole construction.

In the end, it's simply a calculation that you have to make individually.

And as for your small change requests, with the standard house you reach into the drawer and the statics are finished. As soon as you move a wall on the upper floor, a new statics calculation is required. Of course, you pay for this as well as the planning changes as the corresponding preparation.
