Hello Shism,
With all these m² prices, you have to be very careful when comparing, otherwise you compare apples with pears...
Yep - and even then it cannot be compared 100% because personal taste cannot be quantified
Bauexperte calculates, if I work it backwards (380k for 220m² + basement), probably with ~1730€/m² living space...
No, I always calculate in the first step basically without basement and a price per square meter of €1,500.00/sqm/LS for central Germany; I work exclusively within a manageable radius around the Rhineland. In the north it is cheaper, in the south of the country noticeably more expensive. Because I also prepare appraisals, I have a fairly good overview of the pricing structure in construction in Germany.
With my architect, the basement is not included in the 1300€... it is charged separately at 800€/m²... Furthermore, the architect does not calculate with 1300€/m² living space but with 1300€/m² gross area...
If I then convert that, I come to a price of ~1950€/m² living space including basement... so now suddenly significantly above Bauexperte’s assumption of 1730€!
I have - purely from experience - certain standards for utility basements, as long as they come across as square, practical, and nice. I then add further extras according to the desired equipment; the same applies if the utility basement is not symmetrical.
BUT - and I have to mention this, only here on the HBF, as a rough value for potential builders. In real business life, I calculate the exact dimensions of each individual construction project, starting from the earthworks up to the desired equipment.
However, with my architect, the ancillary costs are already included in this price, whereas with Bauexperte’s 1730 probably not... with a difference of ~200€/m² you would thus arrive at ~44k ancillary costs for 220m² living space, which Bauexperte would probably not consider completely unrealistic...
Calculating a price per square meter all-in is – in my opinion – a bad habit of many architects; because it leads exactly to the aforementioned example of apples and pears.
The catch with architect-prepared offers is that they cannot determine the exact final price at the beginning at all; their offer only becomes concrete when the individual returns of the tender arrive. Ultimately, it almost always ends up in the realm of a seriously offering general contractor, also because the equipment – e.g. sanitary or tile proportion – is tendered at a higher quality. Hence also the – unfortunately also here – often made statement that an architect is more expensive. An architect is, soberly considered, not more expensive than comparable providers. However, the advantage of an architect clearly lies in their ability to plan a single-family house individually, which most catalog providers cannot do; of course only if there is a creative spirit within them
Important in all of this – whether created by FH/timber frame/solid house providers or architect – is to clarify the financial framework in advance. From this sum "X" consider the ancillary costs as well as a reserve for extras, then – by human reckoning and also provided due care was exercised in the selection of the building partner – nothing can go wrong. Regardless of this, every builder must be aware that there is no defect-free construction project, because too many people work on the creation of a single-family house; it must be handed over free of defects!
Best regards
