Floor plan single-family house ~165m² plus basement

The plot is 680m2 in size

I actually meant the lengths of the property boundaries, especially the width at the street.

He didn't know yet if he would fill in the rest of the area on the left.

What's he like? Can you talk to him? If yes, I would invite him for a beer and coordinate the plans so that none of you has to set any L-bricks or the rainwater runs to the neighbor, the fence falls over, or similar crap. Of course, such agreements are ultimately null and void when it matters. But I would give it a try.

The plot is 680m2 in size and garages / carports may be built on the property boundary.

But this refers to the side property boundaries and not the front one at the street, right?!

I want to lay down some grass pavers / paving stones where S S (parking space) is indicated and not declare it as a garage / carport / parking space. I would still park my cars and the cars of my children there (once they turn 18). The building permit states a garage with a 5m distance to the street. Since the curb is not very high, it is no problem to drive from the street onto the property. I once read somewhere that there may only be one property entrance.

You can talk to my neighbor. I have already had a beer with him. :D But that was right after purchasing the property, and I hadn't really given it much thought myself yet.

The dimensions of the property are as follows. Length along the access road approx. 21.03m (north). The sides approx. 35.5m (west) and approx. 32.34m (east). At the very back in the south it is approx. 20.26m. I obtained the values from the Geoportal.

Of the 2 GUs who are shortlisted, one is making a planning contract for the service phases HOAI 1-4. The other unfortunately does not offer this, so we will commission a separate architect. (HOAI 1-3)

I said above that one of the GUs does not make a separate planning contract. That was not quite correct.

We created a similar floor plan with the GU as in this thread and I also received a good offer for it. He has now offered that I sign the house construction contract / offer, the planning contract, and that we adjust the contract retrospectively. My offer to sign only the planning contract was initially rejected. To be honest, I am somewhat skeptical whether I can do it this way or whether it would be better to commission a separate architect. The trust in the GU is basically there. What do you think?

I said above that one of the GUs does not make a separate planning contract. That was not entirely correct.

That the GU does not offer the planning contract standalone was, to put it simply, for "trade law" reasons and indicates that he would also commission a freelance architect just as you can do yourself (which in my opinion is also the best way). I would only choose the GU if your trust in him is shared by your architect. If you have not yet read my Phase 5 mantra, I am happy to repeat it here again: with the drawing attachments of the building application from service phase 4 you are allowed to build the house, but you cannot yet do so. The waiver of service phase 5 will be bitterly paid for on the one hand with stigmas in the form of drywall casings for all kinds of piping guts, and also with additional effort in service phase 8.

Attached is the section of the house.

I do not like the cantilever of the bay window at all: if executed as crudely as shown in the plan, you will have little pleasure with it, and if done properly, you will save—if at all—only a few hundred euros compared to building the bay window already in the cellar. The seemingly cheaper variant is more complex in this particular case.

Where did the floor plan shown here in front come from? (It is full of dimensions that indicate very special building materials or a non-masonry construction.) The best buildings with, I would say, a “planning-involved GU” (especially if you consider omitting service phases 6 and 7) are created with the least possible variation of one of his standard building proposals; second best are consistent individual plans; and almost guaranteed to be defective is to change a standard building proposal of the GU significantly (including dimensions): in such cases, the “always-somehow” method leads to the greatest discrepancies between the target and the actual.

Well, I wonder if the stairwell window is really that useful. You’re standing on the landing at about 1.65m. There’s nothing left in height there. Or is the view just drawn incorrectly? And in the bedroom, first draw in your bed and then a wardrobe. Maybe the gable window in that room will have to disappear. Just my opinion
