ᐅ Is the floor plan for a single-family house structurally feasible?

We have planned the floor layout of our future single-family house according to our wishes. However, before we consult an architect or structural engineer, I would like to ask here whether the floor plan is structurally somewhat realistic.

Exterior walls: 50 cm (20 inches) brick
Interior walls: 30 cm (12 inches) brick

The dimensions refer to the interior measurements (so without the brick thickness).
I have fewer concerns about the right side. But can the left side be realized as planned (without any extensive special constructions)?

Thank you very much for your help/opinions.

Of course, something like this can be realized, as the dimensions are not very large. However, only a structural engineer can tell you which measures are necessary (such as a reinforced concrete wall by the stairs, beams, etc.).

Maybe a thicker ceiling is needed 🙂 It's the same for us... we are going with 30cm (12 inches) now

I am still looking for the entrance.

The kitchen seems tiny to me. How deep is it? 2m (6.6 feet)?

Thank you all for your quick responses 🙂

@nordanney: Do you know the rough price difference between a "standard" 4-meter (13 feet) wall made of 30 cm (12 inches) bricks and a 4-meter (13 feet) concrete wall?

@Steffen80: What thickness was originally planned? How much more did the thicker slab cost you?

@Masipulami: about 2.90 x 3.10 meters (so just under 9 m² (97 sq ft))... too small in your opinion?

The entrance is next to the garage door 😉
