Hello,

after completing the purchase of the plot, we plan to start construction in spring 2019. At the moment, we only have a preliminary floor plan draft. The floor plan design should be finalized within the next few weeks so that we can submit the building permit / planning permission application in September.

Attached are exterior views, the site plan (our plot marked with a red X), drafts of the ground floor and upper floor, and a view of the terrace from the living/dining area.

With the plot width of 20.7m (68 feet), and the minimum setback of 3m (10 feet) from the neighbor, we are limited to a maximum outer dimension of 14.7m (48 feet) including a double garage. It might be possible to build over the double garage on the upper floor, but that would result in additional costs.
We want to keep the living space under 150 sqm (1,615 sq ft) due to construction costs.

Current changes we want to discuss with the architect at the next meeting:

Ground Floor (GF):

- Kitchen/dining area 30-40cm (12-16 inches) wider (shift everything upwards, reduce staircase, hallway, and built-over corner)
- Living area slightly wider and longer (reduce utility room size slightly / possibly reduce staircase width from 1m (39 inches) to 90cm (35 inches), maybe narrow the hallway a bit)

Upper Floor (UF):

- Overall room layout change (due to straight staircase and hallway in the middle of the house it’s quite tricky):
- Bedroom should remain in the northeast for sunlight exposure
- Bathroom needs to be larger but must remain in the southwest due to the kitchen location below (minimum 11-12 sqm (118-129 sq ft), so children’s rooms can be a bit smaller, around 10-11 sqm (108-118 sq ft), possibly a workspace can be as small as 8 sqm (86 sq ft))

Do you have any ideas for a better room layout upstairs?
The staircase could also start from the hallway instead of the dining area as shown here.
We actually like the solid straight staircase leading from the living-dining area, maybe one side wall of the stair could be shortened so that the staircase is open on one side at the beginning.
With the central ventilation system, are the typical downsides (warm air or cooking odors rising) somewhat compensated? Noise between the ground floor and upper floor should be limited since the staircase isn’t completely open to the living room, right?
We also plan to build a small room under the staircase in the hallway that is accessible from upstairs (near the utility room).

We hope we haven’t forgotten anything and that you can get a rough idea. Suggestions and critiques are welcome.
Thank you in advance for your effort and advice!

Ground floor plan: Garage, hallway, utility room, WC, living, dining/kitchen, terrace.

Upper floor plan: Hallway, office, bedroom, child 1, child 2, bathroom, staircase.

I would choose a different staircase. A straight staircase takes up too much space.
The children's bedrooms have a very poor layout.

Considering only the kitchen/dining/living area, I think it's good. I would rotate the staircase because later the teenagers will have to pass by your bedroom at night.
Swap the bathroom and the workspace.

Mmh... there is a missing window in the bathroom. Just to get that out of the way.
The whole design is definitely different, but I wouldn’t want to live in it. If it’s going to stay like this, I would reverse the direction of the staircase.
I don’t see a reason for such a thick wall between the stairs and the hallway. Also, the hallway is quite spacious for a house of this size. Apart from the bedroom, the upper floor consists only of narrow, corridor-like rooms due to the staircase. Having less than 10m2 (108 sq ft) of living space is almost a planning mistake. So no, I wouldn’t build it like this.
Clear thing: the staircase needs to go and be replaced with a more space-saving version. The large hallway should be reduced and added to the living area. The upper floor needs a complete redesign.

Typical scenario: expensive woman (even if it’s just the legs) gets kidnapped by two adolescent males.
Who comes up with this stuff?

Less hallway space would be more appropriate.

I like that the straight staircase starts in the dining/living area; we'll do the same. Of course, you need to know what you're getting into (children/teenagers crossing the living room, etc.).

I think the house has some interesting ideas, but overall, I wouldn’t want to live in it. In my opinion, the house is too narrow for a straight central staircase. We have 0.5 m (1.6 ft) more space upstairs and even more in some parts of the ground floor, and we still struggle with the dimensions.

I also find the living room under 10 sqm (108 sq ft) way too small, especially compared to the other room sizes. The hallway areas seem like a complete waste of space.

I generally like the L-shape on the ground floor.

Are you planning to park cars in your garage? If so, I wonder where you would have storage space and so on. That seems very tight to me. But, of course, everyone has different priorities.

I find the layout of the upstairs pretty awful. I would start over completely.

Maybe consider moving the staircase further "upwards"?
