Hello everyone,

I’m new here and would appreciate your ideas. We are planning a 150 sqm (1,615 sq ft) semi-detached house and are looking for the optimal floor plan.

Development Plan/Restrictions
The building envelope is used to its full extent.

Builders’ Requirements
- As clever a floor plan as possible
- The house will be occupied by two adults and two children (4 and 6 years old)
- The ground floor and upper floor should be able to be lived in separately (aging in place)
- No overly extravagant or expensive features should be used
- Basement with a technical room is available
- Prefer architectural style and conservative construction methods
- Open kitchen, but more of a kitchen-living area. The “living/media area” should be part of the kitchen-living space

What is the most important/basic question about the floor plan in 130 characters?
- Are there better ways to use the space and are the room sizes suitable for normal use?
- Does the layout suit a family and two living units for the future?

...And anyone who has even a bit of experience with design in house construction, or simply with living spaces, can immediately spot the mistakes in a 2D plan.
Actually, already in the questionnaire ;-)
Although I will probably never be able to understand how someone can’t mentally convert a 2D plan into 3D, these programs do seem to be considered very helpful by many homeowners. Unfortunately, perception of proportions can’t be “added” by software as well, so those with difficulty in aesthetics often resort to the “safe bet” of symmetry...

My goal was to save everyone time by not responding to things that are already fixed.

Then just state in the first post what is fixed: existing basement, requirements from the building authority so that it resembles the irreparable original house from years ago, and so on. All of this is relevant to assess whether the floor plan even makes sense. Because:

is not relevant to my question at all.

Where the garden is located and how its layout looks is very much relevant, just like the existing surrounding buildings. You don’t want to place a glass house right next to a 2m (6.5 ft) front yard and—as has already been criticized—have the patio door right in front of the dining table. House, plot, and neighborhood are a unity. This is even more true for existing buildings than for new developments, where your neighbor Müllermeier might submit his building permit / planning permission two years after you do, and until then you have to guess what and where he will build.

Why should the house potentially be suitable for two separate apartments at some point in the future? No one knows when that future might be, and the possibility of moving to just one floor might never even arise!
This might be somewhat manageable in a larger house, but with a semi-detached house of 150 m² (1,615 sq ft), it’s simply not practical, as the floor plan clearly shows.
Carefully consider whether you want to live comfortably now with children and have a suitable living concept, or if you want to limit your space and living comfort for years to come just to be prepared for possibly living on one floor in many years. As currently planned, living is uncomfortable both now and later in two separate apartments, as others have already explained.

That doesn’t make any sense and that’s the reason for your frustration. You want to quickly discuss a half-baked idea without any solid foundation, making us waste time and brainpower? Okay, here’s an assessment of your rough draft:

General:
The ground floor and upper floor dimensions don’t align. That’s already a deal-breaker, unless there’s a 12cm (5 inches) setback on the ground floor?
There’s a basement which the building sits on? Where is the access to it? Are the stairs aligned exactly on top of each other? What kind of roof does the building have? How high are the floor-to-ceiling heights? What does the zoning plan / building permit say about this? How thick are the external walls, and what materials are used regarding energy saving regulations? The staircase seems disproportionately large.

Ground Floor:
You run into a corner as soon as you enter the house. The open-plan kitchen/living area is too small for four people as the main living space. The table blocks the exit to the (potential) terrace. It’s hardly possible to sit there, and the chairs next to the terrace door are unusable anyway. The pantry is too narrow to fit any shelving—a complete waste of space. Please try furnishing the guest room! It is completely unsuitable as a bedroom in case of a later separation (which is a nonsense scenario anyway). The bathroom is disproportionately large. Why is the washing machine there if there is a basement?

Upper Floor:
Long, dark, narrow corridor is questionable and unattractive. The bedroom is very cramped. When you open the wardrobe door, you fall onto the bed. Dressing is only possible alone and requires acrobatics. The WC drainage will probably be a challenge.

Also: Where is south? Depending on that, the children’s rooms or the kitchen/living area will be relatively dark.

Thanks for the comments, they help me move forward.

And again, it’s not JUST MY rough draft, it’s a shared draft with the architect. That’s why the stairs and the load-bearing walls are aligned on top of each other. The stairs also end exactly at the edge of the small basement. What exactly is missing in the guest room? Is it too narrow?
We “squeezed in” the storage room. Ok, and the 12cm (5 inches) missing on the ground floor at the left wall was due to a drafting error. The roof is still undefined. I can’t say anything about the WC drainage. The architect must have had a plan for it.
The washing machine shouldn’t go in the basement because we don’t want to go up and down stairs all the time. We don’t have space or budget for a residential elevator :p.

South is missing on the plan, north is marked.

Hello KleinUndFein,

my advice based on painful experience: start with the staircase. It determines the entire floor plan. And a small tip—a half-landing staircase takes up an enormous amount of space. I would choose a space-saving half-turn staircase.

Thank you. We will discuss this with the architect.

3. If this was your idea, it makes me sad that you don’t see how paradoxical some things are. You think you can play the expert, but you are bringing an amateur idea into a professional league.

No, we’re not pretending to be experts. We are simply the ones who want to live there! We need the professional so that the house is built in a sensible way that suits how we want to live in it.

A house is planned; you don’t just line up rooms along a corridor. You take measurements so that rooms can be furnished according to their intended use. You don’t put a utility room (AB) in the already very small living room corner, no dining door opposite the bathroom door, and a ground floor bathroom that looks more like one from a 1960s agricultural building. Children’s rooms don’t only face north and have a 90cm (35 inch) “low” window with an extra-high window sill, making sure they get to know the gloominess, while the upstairs bedroom has a 4 square meter (43 square feet) window facing south that practically overheats the room. The hallway window upstairs is placed arbitrarily, leading to nowhere. The front door makes furnishing the entrance niche difficult.

What would your suggestion be? Calling the ground floor bathroom “like one from a 1960s agricultural building” is quite a harsh statement without any explanation or better alternative. What would you do differently?

And why should a forum or every user who speaks up praise this floor plan if it isn’t good? Even the dimensions used weren’t properly considered, and the ground and upper floors aren’t congruent. Since you withhold important information, the forum doesn’t come up with any clever ideas or sudden insights. That’s just how it is… No money, no honey, as I already mentioned. Maybe you just don’t understand.

If I were looking for praise, I wouldn’t have posted the proposals.

Regarding congruence, see above. The mouse slipped—no one is perfect.

What’s interesting is that now everyone is criticizing, and hardly anyone offers a suggestion. I’m starting to believe that everyone here is stuck in their own ideas, and a collaborative design is impossible. In other words, 90% just say “this is rubbish.” Please, give me an example plan with roughly similar dimensions showing what it should look like so that not everyone here loses their minds :-D.
