Floor plan of a single-family house with basement

Silly question: what does a lifting station have to do with a shower or washing machine, I thought you only needed that when the sewer is higher than/equal to the house connection? So no matter what water occurs in the basement...?

- Nice plot, I would give the house more windows facing the garden

The staircase idea is also a good one. Leave out the winding part upstairs!

- I always find that niche next to the stairs on the upper floor very unfortunate (usually it just gets dusty with an old lady's armchair or something)

That was the question. Is this the 2m line? Otherwise, the bathtub is often pushed further under the slope. Now there is dead space behind the bathtub.

It must be drained below the backwater level in (almost) every construction project. This means that every shower/sink/toilet in the basement requires a Sanibroy/lifting system.

So every consumer (in the basement) needs an individual lift, and there isn’t one for EVERYTHING that occurs. OK, then that’s clear.

Yes, the plot looks good. What can be found next door? Are there houses there, is there still construction going on? Where are the garages there? How tall is the nearest tree?
Based on these circumstances, the house should be planned with the window and room arrangements.
The house you have now chosen is quite a normal standard and comes in different sizes. Your size is already quite a big number ;) If you plan to stay in the house as long as possible, I would a) give the bathroom an age-appropriate size and b) also plan a bedroom. Or alternatively a stair landing that can accommodate a stairlift.
The construction company probably has other houses in standard that could be upgraded accordingly?!
Tip: other companies also have their model houses, mostly very similar, but often there are small special components that can be adopted.

I think a more elongated house shape offers more satisfactory possibilities.

A quarter-turn staircase will probably be somewhat longer?
But as already said: given the house size, consider a different layout because no one wants to have the dirt from the entrance on their stockings when going up the stairs.

I actually always find this niche very cozy. But that might also be because I have never lived in such a conventional house with this stairwell ;)

No, this area is usually always bricked up (installation lines often disappear behind it).
