Single-family house floor plan / Feedback, criticism and suggestions

The counter-proposals no longer correspond to our ideas

Can you specify that again? Which ideas are not being taken into account? Your spatial program does not seem so extraordinary to me that it could not be done smaller and more efficiently.

The utility room with cloakroom corridor is a good example of turning a lot of sqm and money into little living comfort

@Ysop***’s question is important. Simply cutting out a few sqm is not an option. A replanning is necessary. Size alone does not provide comfort or spaciousness.

Reflect and consider where it really pinches with us. A little more everywhere does not necessarily lead to success

A very strange structure. Qm, where they are not needed. For example, access to food. Hallway upstairs larger than downstairs. Cloakroom then with a view of the washing machine and clothes rack. Pantry in the last corner, assuming the access point. And no, you can't just shrink the thing to make it better, only "Back to start" helps.

I’m not familiar with the prices in the Hannover region,

They are still very reasonable there. But even there, the world has moved on – and with it, the price level.

Can you be more specific? Which ideas are not being taken into account? Your space program doesn’t seem so extraordinary that it couldn’t be achieved smaller and more efficiently.

I would like to see the GU’s design.

Unfortunately, I relied too much on prices of 1,800 to 2,000 euros per m2 of living space in our cost estimate.

But basically, your approach is now hard to understand: GU and your limit do not match. You recognize that “suddenly today” everything is more expensive. The drawing is made with a “whatever program,” which shows nice views and suggests professionalism in the line work. You are so attached to your design that you don’t want to part with it. The GU’s design doesn’t even open your eyes to the fact that you need to do without size (or probably a lot of frills in the facade design). When I read something like this (it only develops over the course of the thread), it’s unclear to me over how much time this development has stretched for you. By that, I actually mean the opposite, since your development is missing for me – confronting yourselves with the info about price and drawing from the GU and then working with that. Why is this design still posted here if the truth about the numbers is clear?
Time should teach you that you have to let go of your unaffordable idea.
It is like this: the GU’s estimate, i.e., the 470,000, refers to HIS design, which apparently has little to do with yours.
You have to react somehow. I mean react in the process. Not even a forum can change the numbers.
Basically, it is not really about the design itself for you here, but your question at the end:

How do I manage to optimize the living space as best as possible regarding cost savings, is the floor plan design compatible with our price limit? What’s the next step, going to the architect or developer/GC?

Unfortunately, my pinned posts no longer exist in this forum. I once wrote in a post that psychologically, one falls in love with and is chained to their project created with the program, that one can no longer let go because one is happy to be able to draw walls so well, where, among other things, the dream kitchen is then shown in color, the favorite sofa, everything you would like to see. And the mistakes made are unconsciously prettified more with each day. This has fatal consequences of losing touch with reality, so you have to start over. That acceptance is then missing.
And the consequence is that a lot of time is wasted. So how much time has now passed between realizing that you can no longer get a house for 1,899€ and your post today? All this, the holding on and not reacting, fits your attitude in your current house.
Fact:
Your design cannot be reduced with just a few changes, nor does your price limit of 500,000 including ancillary construction costs allow for elaborate facade design, expensive flat roof bays, or the dream double garage. It may be that one of these is possible through the Lower Saxony bonus.
The requested fireplace also costs AI 15,000€.
But even 100,000€ more in the budget does not make the design better inside. It is too stretched out, as if you don’t know how rooms relate to each other without corridors or with a corridor in the middle of the house.

I just want to briefly mention regarding the space requirements that four of us live on 80sqm and everything is completely full. However, I fear that we would fill 200sqm in a short time as well. It always depends a bit on the ability to declutter how much space you need, so it's better to build smaller, and with 470k already much smaller.

I briefly want to mention the space requirement here, that the four of us live on 80sqm and everything is packed full. However, I fear that we would also fill 200sqm in a short time. It always depends a bit on the ability to declutter how much space one needs.

You can always fill everything up, in my experience. I think it depends solely on self-discipline and willingness to let go of old things or only buy new things to a limited extent, if you want it that way. I once rented out my former house, and the two tenants had packed the previously empty attic and a large shed all the way to the roof. Relatives of ours just moved and had over 100 !!! moving boxes in addition to the already large moving truck. It’s especially about the individual definition of "what do I need"—plus here comes "what can I afford"; that then partly answers the previous point.
