ᐅ Price Increase – Our Construction Company Wants 21.4% More

These are the questions: what is included and how do you compare it?
The following items are included for us:

- electric roller shutters
- 10 m³ (353 ft³) rainwater cistern
- photovoltaic system (13.29 kWp)
- controlled residential ventilation system
- increased ceiling height to 3.00 m (9 ft 10 in) (shell construction height)
- fireplace including flue
- double-sided coated windows
- etc.

There are so many items you could include or exclude. That’s why a comparison price is really difficult, as it would need to be standardized.

No, that is actually quite simple. Basic finish, standard finish, upscale finish, or high-end finish. The finish levels are quite well defined, similar to those used in rent indices or similar.

I also find it difficult to specify the price per square meter. For example, if we only have a utility basement, it will never have the same price per square meter as the residential ground floor or residential attic floor... so these figures are very, very difficult to determine.

It always refers only to the living area. The basement is separate and is either not included or mentioned as an addition.

However, if I don't know the cost of my basement (which is not necessarily clear with a general contractor), then the total price INCLUDING basement obviously distorts the price per square meter WITHOUT basement significantly.

No. The basement also has its own price per m² (square meter). Only the additional construction costs, like earthworks, can vary significantly.
The typical price per m² (square meter) refers to everything directly connected to the house. This includes the kitchen, stairs, railings, floors, and so on.
...The TV, of course, if it’s mounted on the wall, does not count 😉

Additional costs are expenses that arise alongside the construction. A fireplace is built and is part of the house. So, to answer your question: yes, it is naturally included in the construction costs, just like a luxury bathroom or KNX system.

That is why, for me, the kitchen is also directly part of the construction costs. Without a kitchen, it’s not really a house.
But you can discuss that endlessly. It’s a difficult topic.
