ᐅ New construction of a single-family house with 150 sqm of living space, Saarland

There will be no bathtub, neither upstairs nor downstairs.
The upper floor (first floor) could look like this:

The small room at the front could possibly be used as a kind of "gallery."

Looking at it more closely now, you could rearrange the new layout by swapping the master bedroom, dressing room, and bathroom, and move the two children's rooms to the right side.

You can really do without the questionnaire! I hope the house isn’t built just as carelessly. I can’t make anything of it.

No bathtub is as excessive as two. So why not just one?
Here come two more unknown family members.
Consider swapping the kitchen and living area. At least the kitchen would be closer to the terrace.
Please draw proper furniture in the open-plan room. Kitchen, dining table, and cabinet won't work like this in reality.

Kids planned but no bathtub??? 😀 You clearly have no experience with life with children. Better plan to include one. 🙂

Overall, I get the impression that no real planning took place before creating this design. You just rolled the dice for the house dimensions and then divided the space somehow. People who call every box “Bauhaus” might as well call it “Mondrian” ;-).

To put it simply: the entire drawing is invalid – EVERYTHING will be different :-(

What is the dashed line supposed to represent: the ridge?

Number of floors: 1.5, and the upper floor should have a knee wall height of 2m (6 ft 7 in)

A knee wall height of 2m (6 ft 7 in) only makes sense if the eave height restriction prevents a full two-story design despite having two floors.

Then they aren’t really an architect.

The straight staircase is for the look,

What look? The house is too small for the staircase to act as a sculptural feature.

@chrisOo It’s not about simply filling out the form, but about your individual habits, preferences, and the WHY behind them. Anyone can live behind any door. Maybe you could provide a bit more information...

I would definitely include a bathtub in the house, especially because of children — and I say this as someone who doesn’t usually take baths. Upstairs there is plenty of space in the bathroom.

You absolutely need to include all dimensions, furniture, bed, dining table, sofa. The bedroom on the upper floor could feel very tight at 10m² (108ft²). I would skip the sliding door there, especially since it’s usually left open anyway.

Plot size: very large to huge. Plenty of space available.

So why does the house have to be two stories, with a knee wall of 2m (6.5ft)? That can cause issues like windows being too low for regular windows or too high for roof windows. Why not have more ground floor space with a more generous open-plan living area, and less upstairs? Or do you have a specific house style like a villa in mind? You said you have a huge, beautiful plot...

Gabled roof, but relatively flat.

Why? Is that based on your living preferences?

chrisOo schrieb:

Modern but simple and plain.

That alone won’t necessarily make it cheaper. Most people (myself included) say “simple” but often still go for the high-end options.

chrisOo schrieb:

Open or closed architecture: open at the back, where there is a large, wide garden.

So why are you not really designing that area to be open and spacious? There currently aren’t many windows facing what you call the prime side, and the open-plan area is quite small.

chrisOo schrieb:

Balcony, roof terrace: yes, there is enough space around the house.

Where exactly is the terrace supposed to be? Where is the “prime side” of the house? Maybe consider a smaller terrace separately for morning or evening sun, or to enjoy some quiet time in the shade?

Then it’s probably not a “free” architect; a professional would likely refuse to just redraw someone else’s plan. Is this going to be a general contractor build? A prefab house? Are you already committed to a specific route?

What do you especially like? Why? The straight staircase for the look, open area, and orientation to the back.

A staircase like that needs a proper amount of space to have the intended effect.

Currently, your plan has a narrow endless corridor, which with 11.62m² (125ft²) is one of the largest rooms in the house. By the time you reach the kitchen, you’ll be parched. Leaving the kitchen feels like going through a maze. A cloakroom, etc., is only possible under the stairs so far.

Once you have drawn in the real furniture sizes, you will notice space is tight everywhere. Let go of all your ideas and internal requirements for a moment and start from scratch based on your actual needs! Whether it’s a flat x-roof, with or without a gallery, or a straight staircase, doesn’t really matter. These unnecessary specific demands are currently preventing a good floor plan.

First of all, I would move the office upstairs or enlarge the ground floor to create a decent amount of space in the open-plan area downstairs. Right now, it’s just 34m² (366ft²)!

The utility room could get a few more square meters, the ground floor bathroom without a bathtub could give up some space, the staircase should be appropriate to the house size, so you also get a proper cloakroom. I have built before and “forgot” the cloakroom — what a nightmare!
