Is new construction under 400k€ still actually possible?

To standard. I do not consider anthracite windows, nor lift-and-slide doors, nor roller shutters to be standard. Why would I! The window quality is not changed at all by gray film. The lift-and-slide door does not provide a different access to the garden than tilt-and-turn. Etc. Roller shutters, why? We have pleated blinds all around for 1200,- which also provide shade. Our house 163. Garage 8. Earthworks 7, connections etc. 10, kitchen 5. Painting and floors 7, landscaping 15, 71 land. 1 surveying. That makes 287. Again regarding the question whether it can be done under 400, yes yes yes. But but but with discipline. Now I also resist the term spartan for what we have. What comfort do my wife and I really give up? The shower is level with the floor, heating in the floor, door keys are really not a minus in comfort. Even a few built-in spots were included in the budget. I maintain that a part of the exploding construction costs in D are caused by the builders themselves. I do not consider the often-cited 2000 per sqm to be mandatory, even if they may often be correct. K.

Aren't you still planning the layout of the bathroom? How far along are you? Not that I want to say you can't manage it. I just would be cautious in the "planning phase" with statements like how much it will end up being +\- 10,000€. That can also go wrong.

Yes, the layout ultimately stayed as in the picture... the other variants were partly difficult in terms of space or my husband did not like them. I’m not committing to +/- 10,000 either but we would be at about +50k to end up at 400k.... that it won't go higher can definitely be estimated. The selection of fittings is basically finished (only minor things left, but we agree on what we want).

I am generally rather humorous, but to describe roller shutters as a special feature seems a bit exaggerated to me. To be honest, I have never seen a house without them in my life. What’s next? Skipping the front door and entering the house through the bathroom window?

You are BW. Here in SH roller shutters are exotic. Really.

Really, you don't know any houses without [Rollläden]? It must be something regional. Here with us, [Rollläden] are normal not only in new buildings, in the north where our second home is, [Rollläden] are the exception but there you get the outlet tornado including, which I didn’t know here a bit further south.

To be honest, I have never seen a house without them in my life.

Then take a good look on your next vacation!
Even here, people may be a bit reserved, but they do not have a panic fear of imagined curious glances.
Only in the ... estimated last decade have more and more roller shutters been installed because of burglary protection. Since the energy saving regulations, they must be installed in the south as heat protection.
These clattering jalousies have just become fashionable along with the cube houses. I consider the weather here far too windy for those things.

for that, there is the socket tornado included which I didn't know here a bit further south

Do you mean the exaggerated number?
