Most other things can be done without. Barrier-free shower with shampoo compartment? That works with a shower tray too. prettier toilet? Concealed fixtures? That works without as well. Double door with light panels, country house staircase made of limed oak, segmental arches above the windows, sash windows – those are all nice to have, but if you just want to live in your own home, they’re not decisive. You can live with the standard number of sockets too.
Of these things, we will only have the sockets because we can do those ourselves and the material cost is not significant...
I had to look up sash windows because I’ve never consciously seen anything like that before. Here, everyone wants as large glass surfaces as possible WITHOUT anything in between, which wasn’t technically possible in the past. It’s interesting that someone pays for the opposite.
But of course almost every builder has such cost drivers. For us, they are called cellar, plastic-aluminum windows, fireplace, lift-and-slide door, interior sliding door, and double garage.
It definitely is more fun if you can at least realize something yourself, but of course, the difference in happiness between plastic and aluminum windows is probably quite small in the end.
Regarding the catalog price, you have to see whether you can place the desired house on the property, right? For us, the development plan already specified the 8m x 10m building window and that was difficult with a standardized model house. And the individually planned prefab houses weren’t really cheap either.
