We are currently building and started at the beginning of June.
There is definitely some room for negotiation in terms of price, but not so much that prices can just be pushed down easily. Within the framework of the architect's planning, for example, we have 2 items that turned out to be cheaper in reality than they were planned in March of this year.
Screed: The architect had planned around €13,000 for screed, insulation, application, etc. Living area: 180sqm + garage + technical room
Paid: just under €9,500, even though we took the additional item of fast-drying screed, which was €1,000 extra. Thus, €8,500 would have been possible with a longer heating phase.
Another example: drywall construction
Around €4,800 was planned here and we paid €2,800.
At the same time, however, windows and the roof were more expensive than expected/planned by the architect.
I am slowly getting a total cost picture, as the "major" trades such as shell construction, windows, roof, plaster, etc. are done and we will probably end up at €2,300 - €2,400/sqm.
However, we do not have a general contractor, but rather self-assignment and also contributed a lot of own work. Price, of course, without land. Including land, we are also >€3,000/sqm (referring to the house).
