Hello everyone,
I am planning to demolish my existing semi-detached house and build a modern residential building on my property.
The new house will again be attached directly to the existing neighboring half.
The plot measures 1,027 sqm (about 11,060 sq ft), and the design comes from my architect.
I would appreciate honest and constructive feedback on the floor plan and room layout.
Elevations and floor plans are attached.

I’m definitely no kitchen expert, but the straight path here leads directly to the edge of the island, which is probably due to the currently rather trendy pantry; otherwise, the kitchen could have been set back a bit from the access area. On the opposite side of the room, however, there is a huge “open space” with no apparent purpose. Do you think a pantry is rather unnecessary? I agree that the kitchen is somewhat awkwardly positioned. We will discuss this again with the architect on Monday. Thanks.

First of all: I love high rooms with plenty of open space.
For a tall room to feel right, there needs to be a good balance between length, width, and height. I don’t see that balance in your design. The open space is 50% taller than it is wide. This ratio seems unfavorable to me — it gives a “shaft-like” appearance. Thank you for your valuable advice and sorry for my late response.
In the meantime, I have independently created a provisional 3D rendering (see attachment).
The proportions should now be suitable to avoid the “shaft-like” look.
What do you think? Could something like this be implemented? Before and after

What do you mean by gallery? Where exactly is there one here?Sorry, I expressed myself incorrectly earlier – I meant that we would like to have a gallery. It is not shown in the current design.

to advocate for a single-story design?!Yes, that is exactly one of the reasons.N

What do you think? Could it be implemented something like this? Before and after It already looks better and reminds me of my “model house picture” on page 2.
However:
No access to the gallery with the current floor plan – and how is it supposed to be used? Only accessible through the bedroom – so more decorative than practical.
Does the additional living space change anything about the single-story design?
You are placing a large window directly on the property line with the neighbor. That is probably not going to be approved.
Overall, the idea is good but will still require a complete redesign of the plot.

By the way: the elevations don’t match the floor plan.
This is due to the extension. It seems that it has changed somewhat during the planning.
Surely. This is just one approach that could be taken and presented to the client to review everything. Maybe they have already settled on it.
Let’s trust the architect’s calculations that this is still a single-story building.
Do you mean you now have 510 square meters (5,490 square feet) of property?
What does the plot look like? Do you have a site plan showing the street, orientation, and the property with the design? Which state or region is it in?
What do you mean by gallery? Where is one here?
A high ceiling in the living area is very different from having no ceiling at all (as it seems here).
I don’t like it as it is, but I can imagine that this is just a placeholder kitchen. It has barely any workspace, and the counter is, well, quite limited.
When I looked at the design last night, I immediately thought there is a missing wall exactly where the three chairs are, which would give structure to the room.
But starting from the beginning:
You have to like the bulky cube. Many want it exactly like this. I am ambivalent – but if I know that inside there is only an open void, higher than what is good for an open space, then I am in favor of change. It would benefit both inside and outside to put more thought into it. The void is also partly meant to justify the single-story design, right?
Entrance “old house”: the three rooms on the ground floor result from the children’s rooms in the attic. Now you don’t know where the street runs or where you would park on the plot. I feel like swapping guest and utility rooms. Maybe I’d also swap laundry/storage/entrance. The original laundry room becomes the entrance with wardrobe cupboards, with a clear line of sight toward the open space and bathroom from the entrance. The guest/hobby room would then be in the corner (south corner?), close to the shower bathroom. The entire hallway would be more structured.
Extension open space: it lacks elements that give the room structure. As I said, my first thought was “there has to be a wall there.” For those who want to watch TV while cooking, they can take a step to the side.
BUT: the kitchen is completely dark! Plus, it has a ceiling. It basically has none of the void or incoming daylight.
My thought would be: kitchen on the outer wall for daylight, chill area can be a bit darker, a stylish three-meter (10 feet) island (or similar), remove the pantry access through the tall cabinet and place the pantry as a structural and load-bearing element in the center of the large open space.
Conceptually, I would consider a void over the kitchen and dining area, but planned, not just left open above. The master area can still be freely adjusted, and so on.Thank you very much for your advice. We will definitely discuss many of these points with the architect. Afterwards, I will send you the revised design. Thanks.
