Hello House Building Forum

I am new here, and we are currently planning our house with an architect. There are currently 4 of us, but we plan to have a 5th. Therefore, the house will include 3 children's bedrooms.

Here is the questionnaire:

Development Plan / Restrictions
Plot size: 1250 sqm (13455 sq ft) on 25m x 50m (82 ft x 164 ft)
Slope: no
Site coverage ratio: 0.4
Floor area ratio: not sure at the moment
Edge development: allowed but I want to avoid it
Number of parking spaces: double carport + 2 cars in front

Roof style: gable roof
Architectural style: classic single-family home
Orientation: see drawing

Owners’ Requirements
Open floor plan on the ground floor, 4 bedrooms on the upper floor, attic with enough space for storage and a hobby area

House Design
Who created the design:
- Architect

What do you like most? Why?
Ground floor: open kitchen and living room. Office accessible from the living room. Direct access to the terrace.
Upper floor: accommodate 3 children’s bedrooms, bedroom with walk-in closet area. The large dormer. The stairs to the attic, where the hobby room will be located.

What do you dislike? Why?
Basically only the staircase to the upper floor. I am a bit bothered by having to walk “around the corner” when coming up. I am looking for ideas to improve this. Or is this concern unfounded?

Cost estimate according to architect/planner:
Not determined yet.

Personal budget limit for the house, including fittings:
350,000 Euro

Preferred heating system:
Gas boiler, solar thermal, and underfloor heating

If you have to give up something, which details or extensions can you do without:
We have already eliminated everything we could possibly do without.

Why is the design the way it is? For example:
We went to the architect with our preferred design. He used our floor plan as a basis and created a floor plan that we like even better. Only the staircase layout is not yet 100% satisfactory for me.

What is the most important/basic question about the floor plan, summarized in 130 characters?
As mentioned, the staircase to the upper floor is my biggest concern. I hope to get some ideas on how to improve it and maybe some feedback on the rest.



Ground floor plan: kitchen/dining/living area, hallway, office, utility room, bathroom, fireplace in the living room.


Upper floor plan with master bedroom, three children’s rooms, bathroom, landing, and storage room.


South is “up” on the drawings



If more information is needed, I am happy to provide it.

Best regards

@kaho674 could you estimate or determine the height or usability of the attic space from your version with the 2 full floors?
Well, I’m working with a roof pitch of around 39° (39 degrees). The usable area should still be larger.
Here is the 2m (6.5 ft) line, but these are always just rough estimates. I don’t know the roof construction your general contractor used.

I think the version looks really nice and I will definitely show the design to my wife. It is quite a radical change though ^^
Yes, please don’t take it too seriously. For me, it’s slowly turning into just playing around.

Your version, which is very close to ours, we like a lot. Especially that the staircase no longer intrudes into the rooms, which makes the upper floor more usable.
That said, you should keep an eye on the dimensions (especially the length). Yours seems to have been significantly shortened. Just to remind you, the area is 3.95 m x 1.30 m (13 ft x 4.3 ft). The kitchen measurements are also not correct. The kitchen island should stand about 1.20 m (4 ft) away from the kitchen counter’s line—that’s a good rule of thumb.

For your second version, this is what we would like:

or like this:

We are currently swinging back and forth between these three options.
Yes, once you start experimenting, making a decision gets increasingly difficult.

The idea might also be to omit the bay window entirely and instead increase the total house depth by about 50 cm (20 inches). This should be almost cost-neutral.

If you want to position the dining table so it can be walked around lengthwise, the width of the dining/kitchen area should be at least 650 cm (255 inches) to avoid bumping into each other at every chair.

For me, it’s also just a bit of fun.

Sometimes the best ideas come from that. It’s definitely very helpful for brainstorming. When my wife says something is completely out of the question for her, then we’re already one step further. If we can’t decide, then we use the process of elimination.

The kitchen measurements are also not accurate. The kitchen island should be about 1.20m (4 ft) away from the kitchen unit—as a general guideline.

Yes, I just made a quick note in Excel to illustrate my idea to my wife. I wanted to keep the effort low, so it wouldn’t hurt too much if this version gets rejected. But since it was received pretty well, I’ll rebuild it in Sweet Home 3D this evening.

I’ve also been experimenting a lot over the last few days. Currently, we are going two ways:

1. Adjusting our existing floor plan (which we both like, except for the mentioned issues) until we can live with the compromises.
-> your version is already very close to that. Of course, the kitchen…

2. Using the input from this thread to try out new ideas and see if something turns out better than option 1.

If you want to have the dining table accessible from the long side, the width of the dining/kitchen area should be at least 650 cm (21 ft 4 in) so you don’t end up bumping into everyone seated.

I had already considered skipping the bay window entirely. We’ll have to see. I have some time this evening to work on it.

It’s actually quite usable. The only downside of the centrally located staircase is that I end up losing quite a bit of space on the top floor that I have to use as a corridor. Maybe it would be possible to build our floor plan (with your improvements) as a two-story design? Or would that not work out with the staircase?

@Sparfuchs_:P ... I just need to get something off my chest ... this is a thread that’s really enjoyable because you can tell that ideas and suggestions are developing in you, and you’re gradually reaching your optimum.

The area that will become the hallway can have a somewhat lounge-like atmosphere; one room will be more of a storage room, and the other the hobby room.
