If the budget with the general contractor (GU) only allows for laminate, but with individual contracts parquet is included at the same price, then I would rather choose parquet than be "just" satisfied with laminate. It's not more expensive than what might have been discussed in talks with the GUs.
This is just one example among many. Upgrading windows (color, material, U-values), interior plaster Q3/Q4 instead of Q2, different electrical installation (more switches/sockets, LAN, automation), larger shower and maybe with rainshower instead of a classic shower rod with showerhead, etc.
There is some truth to the fact that people tend to consume more (and build higher quality) rather than save.
Please explain that to me (I, who built with a GU)
because I simply cannot agree with it.
If the construction specifications state: "Laminate valued at 20 €," but I want parquet with an additional cost of 50 €, then I can have the GU (or GU sub) install that.
Just because you build freely with an architect doesn't mean you get the parquet for 20 €; you also have to see where you get "your" parquet from. It's the same with the GU: I go to the stores and have "my" parquet delivered, which is then installed instead of the laminate.
Also, a GU provides everything that is possible as special equipment: colored, foiled windows, extra windows, special front door, Q4 instead of Q3, cement plaster instead of gypsum plaster... all with an additional cost.
Okay, I admit, some things like Velux windows, etc., may cost certain GUs an extremely higher price, so you no longer want to pay for them... but in that case, you can always arrange special orders with individual trades.
That's how it went at least with our GU! Our upgrades for the electrical, sanitary, and tiling were done exclusively through the trade companies.
