Floor plan proposals - What works, what doesn't?

In short: I would generally avoid extending the hallway and kitchen infinitely long. The ergonomics of the kitchen suffer, the hallway consumes living space. Take a look at Danwood to see how they separate hallways
You know everything else from me through the conversation

Best regards in short

I also think that for a house of this size, 10-12 sqm for the hallway is sufficient; I would rather enlarge the living area with the saved sqm. Maybe consider a different staircase arrangement?

Best regards

For this narrow DUPLEX(9.43), in my opinion, this is the best position for the stairs... Everything else would be even worse... I think..

Your semi-detached house is not narrow at 9.xy meters, even wider than some single-family houses. And yes: it might be that a simply quarter-turned staircase right at the entrance is more suitable - that would have to be tried out. The rooms remain in the same orientation. Disadvantage: the start of the staircase is at the entrance.
In brief, greetings

I will tell the architect tomorrow... or rather today...

So, now I have quickly put together a proof for my thesis that the staircase from the original Eco3 very well fits your house dimensions. For demonstration, I took the ground floor.

a) in comparison Eco3 left without /
right with modification



Original 10.86 x (plus bay window) 9.11 m
Your dimensions 9.43 m x (plus bay window) 10.07 m

So about 1.30 m had to be taken out in width,
and almost 2 m had to be added in depth.

Office / guest room (I did not draw the wall here) would be accessible via the living room in this example, or the door location of the living room could be shifted - it is only a rough “proof” of the possibility within the dimensions. In the example, I deliberately did not shift the bay window back into the relative center of the house, because it only looks better as a detached house in the original; with a pair, it is even more balanced this way.

The operations in detail: “cloakroom” dedicated as a pantry almost linearly shifted and given a corner for the broom; “guest” as kitchen; cloakroom niche instead of side part of the front door; HAR / utility room changed roughly in area and format, the WC allowed that; “guest” and “HAR” share the omitted width amicably. The hallway is no longer a ballroom – ultimately due to the more conveniently located staircase.

b) in comparison left in the same position
Your latest version: you can see, it works.



For the attic floor, a quickly cut-together “drawing” is much more complicated to create, so for now only this much. However, it should be clear here that the operation of placing the staircase at the edge came at the cost of more area used for “circulation” around the stairs. In the attic floor, this also leads to the ruined bathroom layout.
