Single-family house with barrier-free granny flat on the ground floor

I still want to address the budget.

Why should we here, who help in our free time (!!!), philosophize about a hypothetical floor plan that you can't build anyway because you lack the money?

It is clearly exaggerated, but if budget and wishes are far apart – which often happens here in the forum – I prefer to use my free time for more meaningful things.

In this respect, you should not simply dismiss the objection, also in our interest. If the budget doesn't matter or you can pay 200k more, then just say so and the topic is settled. Or if the budget is fixed, then come with EL or something similar as an explanation. But simply excluding and ignoring the issue would be just "stupid" and unfair.

In the driveway?

One initial idea was to place it next to the backup kitchen (that is, to the west). But that has not been our focus so far, even though I am aware that it is also important.

Therefore, I will only roughly address some comments or passages. First of all: in terms of the house type, it is a nice house. It looks as the architect has visualized it, fairly pleasant in impression, even if the entrances do not exactly welcome you, they shy away rather modestly.

That already sounds quite good. What could improve the impression of the entrances?

Living/Dining/Cooking – every second house has this L-shape. The layout is conventional and therefore suitable.
An open all-purpose room is present, whether that now characterizes the modern aspect, I don’t know. What I miss is a sightline from the entrance towards the garden and something other than a U-shaped kitchen. The kitchen is somewhat petty. I would take some space from the pantry/backup. Because a kitchen that does not function to have a backup kitchen, is nonsense.

Exactly, it also says in my original post that the backup kitchen seems too big to me.

I personally find the T-solution boring, this roof terrace questionable – what purpose should it serve if you have to maintain the garden?
I find the dressing room uninviting.

Similar feedback as from , which I had already commented on.

No, it will work. Yes, toilet in the dirty area, yes, very narrow. But no more than a stroller fits there and in an emergency you put on and take off your raincoat in the kitchen, so what.
If you take a little from the backup kitchen on the side, it would be more spacious.

This has given us the most headaches so far. We’ll see, but maybe someone here has a completely different idea. And yes, backup must become smaller.

An apartment for tenants I find complicated. It gets quite tight for two people. You get in each other’s way. The same applies here: definitely check daily work flows. And what furniture is needed? They might want to put a cabinet near the table instead of the 98’’ TV?

Yes, that is really complicated. But there is not much more possible.

203sqm without attic + garage, parking spaces, roof terrace, outdoor facilities and possibly attic development and incidental building costs. Budget 600k ==> Something doesn't add up here. At this size, at least another 750k is missing to be able to build safely (without attic development)

I also think the budget is not enough, but I don't see 1.35 million here. I can't judge the clinker, but that's expensive too. In terms of the room concept, it's more of a city villa with 10*10m + granny flat.

I also believe that the budget is not sufficient, but I don't see 1.35 million here.

Sorry, it should have said that one should calculate with at least 750k.

So, since this is more about the budget than the floor plans, I will give some feedback. I hadn’t seen that had included outdoor facilities and such in his minimum 750k. The questionnaire I filled out refers to the price limit for the house including fittings. My 600k referred to the house (including attic conversion and garage). The roof terrace is now out. For the rest, I am planning 100-150k. If it becomes significantly more (for example another 100k), something will have to be saved on.

The ground floor of the builders can easily be reduced to 10*7m. That is also possible with REH. Then the budget fits. It also helps if you shift the upper floor to the ground floor of the builders.
