ᐅ Floor Plan Assistance: 216 sqm Single-Family Home with Granny Flat and Double Garage

Hello everyone,
We have found a house near Frankfurt/Main where construction is about to begin. It is from a developer. Currently, there is an old house on the property which is being completely renovated. This will be converted into 3 condominiums. Our house will be a single-family home at the back with about 216 sqm (2,325 sq ft).
Two garages need to be integrated into the house, plus one parking space that we can purchase additionally.

Regarding the floor plan, apart from the external walls (a line with property boundary construction and 3.5 m (11.5 ft) to the neighbor) and the double garage, we have complete freedom. We have already modified the floor plan as we want to prepare the upper floor for potential rental at some point (an external staircase will probably not be approved). Hence the second internal staircase.

Basically, we are wondering how to best use the ground floor. Somehow I find it a bit small for cooking/living/dining. (Although I cannot verify the square meter figures, because based on the external dimensions and some calculations it should be about 49 sqm (527 sq ft) instead of approximately 44 sqm (474 sq ft), but I don’t know if the staircase is excluded).
Where is the best place to put a couch?

We also have questions about possible optimizations or mistakes we might have made. Does this all make sense? The architect implemented all of our requests without questioning whether they are practical or sensible. That makes us uncertain.

No basement, one garage for bicycles, and otherwise one room will be sacrificed.
We would like a kitchen island 🙂

The turnkey price is 769,000.
Thanks for your feedback!

I can't imagine an architect designing something like this. Unfortunately, nothing would work with this.

But it does, so what exactly doesn’t work there?

For the kitchen and dining area alone, you already need about 6 m (20 feet) combined. You can figure out how much space remains for the sofa and TV. There is no room left for a cloakroom, and you’re using an enormous amount of space for two staircases. Upstairs, you have plenty of rooms for three people.

I would integrate the sofa/TV area into the guest room and have a spacious dining/kitchen area on the ground floor. Because, as @Myrna_Loy already mentioned, cooking, dining, and living do not work well within 7.30 m (24 feet).

As @Myrna_Loy said, you need 6 meters (20 feet) in a row for cooking and dining.

2. Remove the staircase hall and replace it with a wardrobe. You currently have no space at all for coats and shoes.
I would move the living area upstairs into the guest room.
