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.

whether one is not as loved as the sister/brother, just because one only got the smaller room. And 13 to 16 is already… mmmmh – well… a bit unfair.

As if kids go around measuring with a tape measure?!
But honestly, I find the kids’ rooms a bit narrow. Especially the 2.60 meters (8 feet 6 inches) width isn’t exactly ideal.
That’s why I made my suggestion, which Katja completed.

Edit: I would rather move the wall in the office at least 20 to 30 centimeters (8 to 12 inches), which would benefit child 2.

If you shortened the hallway (it’s kind of unnecessary, that stub), it would be awkward to stand there in the living room. Is there any reason why you wouldn’t just switch the living room and kitchen? It should all be doable and transferable. ...

I seem to recall that having the kitchen directly at the terrace side was an absolute must. And now the living room would be so open. So they’re putting in a wall stub. It does cause a bit of an eyesore, haha.
Maybe you should plan it as non-load-bearing. That way you can knock it down if you realize it’s a mistake after moving in.

Off-topic: My sister and I also had two rooms that were not the same size. We knew that for sure. Not that it caused any problems, but the difference wasn’t as big as it is here.

The rooms being so narrow does bother me a bit as well. That was also a reason why we spent some time working on the layout here. But I’m afraid the original poster has already finished the planning.

Would you install a skylight dome in the hallway ceiling?

If it’s just meant as a daylight spotlight, no. Every flat roof opening you can avoid is beneficial.

I would probably plan a window in the office door.

Or a transom window between the door frame and the ceiling.
