Floor plan draft for a 220m² single-family house

Whether you can still pull that off out of thin air..... you would have to start from scratch. The stairwell doesn’t fit and the existing basement is too small and for the most part only a crawl space.

Well, I don't like the entire draft. To me, it doesn't feel like a well-thought-out overall concept but rather like a patchwork of wishes.

I’ve been wondering all along why a dressing room and a bathroom need access to the balcony, while the children look towards the street (or did I misunderstand that?).
Personally, I would also prefer to have a door between the bedroom and the dressing room. As has been mentioned here many times: if people get up at different times, they don’t disturb each other.
I don’t find a separation between dressing room and bathroom that important, though.

Both children have a very long way to the children's bathroom, doable but suboptimal. This could also be planned differently.

The kitchen absolutely must face the terrace; that makes much more sense from the overall concept. And the passage from the kitchen to the dining area won’t be a bottleneck that way.
Then the office can also be used as a guest room sometimes, and THEN the third shower on the ground floor makes sense as a guest bathroom. But in my opinion, it becomes pointless if the guest always has to walk through the dining/living room first to get to the toilet (I’ll bring up grandma again here, who, when visiting longer, goes to bed earlier than the parents and has a somewhat frail bladder... not exactly a pleasant situation for both parties... even more so with visitors less close to the family).

So, I don’t have a brilliant idea right now, but I don’t like it. I’ll reflect a bit; maybe something will come to me.

By the way: time is running.

After our initial planning, we were actually supposed to be in the final construction phase by now... The fact is, we are submitting the building application NOW. Annoying, but I have to be honest: the planning has benefited from it, even though the basic concept basically fit from the beginning and hardly changed. But we were able to improve many small details, and now overall it fits very well.
Losing a year is frustrating now, but in the long run, I believe we have gained a lot because of it!

This is how they imagine it with the beams.

I just received it as a complete 3D visualization. Tomorrow is the final coordination meeting for the design planning. I have also attached the other views.

One with a hip roof, one with a flat roof.

May I ask about the estimated construction costs? 600k including the basement?

almost 630k. but various things are not included yet. controlled residential ventilation, for example, smart home, security fittings, threshold seals for terrace doors, extra chargeable electrical compared to the construction service description

Base:
128m² basement
228.71m² ground floor/upper floor
26.36m² roof terrace (which actually was not intended by us)

A lot will be revised again.

The original planning by the architect had structural deficiencies. Therefore, some things were simply adjusted, as I posted yesterday. But I have stated that I cannot live with visible beams in the living room. Now some new planning will be done again.

Given the exploded costs, the area will also be adjusted slightly downward. They suggested swapping the master bathroom and master bedroom. I don't think the idea is bad. This way, the master bedroom is more private and the drainage is easier to solve.

It will most likely be the hipped roof solution. about 6000 euros cheaper than the flat roof. And with the flat roof, the architect's stylish design was not statically feasible. And the visualized design sent yesterday no longer had a roof overhang in the area of the children's room at the top and that now looked more like a large block. The flat roof fits better there.

The general contractor is now carrying out the further adjustments with me. His architect is out for now or rather, an employed architect of his is now taking care of the further details.

Too bad, we are not nearly as far as we thought. Until the email came yesterday, we assumed we would only be discussing the costs of the finalized design today, talk about possible savings potentials, building services etc., but now an adjusted planning has to be created again....

Too bad. I would have thought that a designing architect would consider the statics and that such serious surprises wouldn't come at the end of the planning.

that a designing architect also considers the structural engineering

Then he would be a structural engineer and not an architect
He can certainly do that in principle, but not in such detail.
