Hello everyone,
I have read a lot in the forum and am now excited to write my first post :-) I am very curious about your feedback and experiences and look forward to your replies.
Thank you in advance.
If you need any additional views or information for an assessment or feedback, I can gladly provide them. The floor plans for the levels are attached after the questionnaire.
Development Plan / Restrictions
Plot size: 375m² (4036 sq ft)
Slope: no
Site coverage ratio: -
Floor area ratio: -
Building window, building line, and boundary: -
Edge development: no
Number of parking spaces: garage + parking space
Number of floors: 1.5
Roof type: gable roof with 40° pitch
Style
Orientation: east-west (roof slopes)
Maximum heights/limits: eaves height 424cm (14 ft), ridge height = 761cm (25 ft)
Other requirements
Homeowners’ Requirements
Style, roof type, building type: -
Basement, floors: no basement – planned by developer
Number of occupants, ages: 3 (31, 35, 0)
Space requirement on ground floor and upper floor: 130-145m² (1400-1560 sq ft)
Office: family use or home office? Home office (small office needed)
Guest bedrooms per year: 5
Open or closed architecture: open
Traditional or modern construction: modern
Open kitchen, kitchen island: U-shaped kitchen or with island (not essential – must be functional in the floor plan)
Number of dining seats: 6
Fireplace: no
Music/stereo wall: Dolby Surround for TV
Balcony, roof terrace: both as planned by developer
Garage, carport: garage
Utility garden, greenhouse: no special requirements
Wishes: corner bathtub, storage space behind garage to replace basement, possibly a garden shed if possible, gable roof with steep pitch—possible or not recommended at this height?
Soundproofing measures considered if possible
House Design
Who designed the plan:
Planned by developer in cooperation with an architectural firm
What do you particularly like? Why? – open living-dining-kitchen area
What do you not like? Why? – technical room too large? Might limit TV corner – could this be smaller or is that impractical?
Personal price limit for the house, including features: fixed price from developer; for changes or custom upgrades currently planning a 50-60k buffer
Preferred heating technology: planned heat pump
If you had to give up, which details/extensions
- could give up: knee wall / storage space inside the house, separate dressing area
- cannot give up: sofa distance less than 4 meters (13 ft) from TV wall, open living-dining area
Why is the design as it is? E.g.
Standard design from the planner or pre-designed plan already submitted by developer
Currently, we have the following questions:
Is the technical room too large? Might limit the TV corner – can it be smaller or is that impractical?
Is a steep gable possible or is it not recommended at this height?
Would a different staircase shape suit the design of the upper floor or the storage/technical room on the ground floor better?
Could additional living space be gained by measures such as an additional roof window in a clever location or structural changes, e.g., dormer or knee wall height increase, if within the price range (10-15k) and approved by the building authority/planning permission?
I look forward to your feedback and would greatly appreciate your experiences or tips for the “optimal” layout design.

Harald_071123 Jul 2024 20:28At the moment, I like this design best. The only concern I have is the note and the idea about "walking through the living room" or the TV area; I still need to think that over.
@ypg From my research, a utility room of 7.5m² to 8m² (80 to 86 sq ft) should be realistic. Have you had different experiences?
The staircase is drawn with a width of 1m (3.3 ft). Is that too narrow?
@K a t j a This is the kind of staircase it is meant to represent; unfortunately, the software doesn’t offer the exact representation. The furniture dimensions are realistic and correspond quite precisely to our furniture (sofa 3.15m wide (10.3 ft), table 2m x 1m (6.6 ft x 3.3 ft), TV stand 2m wide (6.6 ft)); only the kitchen is just roughly sketched in. In a living-dining area of nearly 50m² (540 sq ft), I think this should still feel spacious enough.

I’m a bit skeptical about the space under the stairs. It’s not empty air or anything. It looks really tight to me. What exactly is supposed to fit in there? Ideally, you should furnish it as well.I’m guessing house connections, the heat pump indoor unit, the fuse box, possibly the solar inverter if it can’t go in the garage storage, and the washing machine and dryer.
I still need to figure out how to cleverly fit all that in.

Can you do without it: knee wall / storage space inside the house, You’re the first person who says they can do without storage space. The only way to explain that is that you don’t do anything at home, not even changing batteries.

@ypg A technical room of 7.5m²–8m² (81ft²–86ft²) should be realistic based on my research, or have you had a different experience? What kind of research? What exactly did you research? Many devices had to be removed because they were installed too close to the wall, making it impossible to access them later with tools.
And you want to move around in that room when doing laundry or taking out the ironing board.
By the way, I refer to this:

What research? What exactly are you researching? Many devices have had to be removed because they were installed so close to the wall that later you can’t reach them with tools. And you want to be able to move around the room when doing laundry or taking out the ironing board.
By the way, I refer you to this:
https://www.hausbau-forum.de/threads/die-liste-die-jeden-bauherren-zu-interessieren-hat.34418/ Is this forum here to help and share information, or to accuse people of not doing anything at home?
The storage room behind the garage is intended as a basement replacement and is 2sqm (22ft²) larger than our current basement. Obviously, that’s not a huge difference, but - drumroll please - cordless screwdrivers, drills, and so on (Bosch and Festool case systems greet you) fit very well.
Also, what I meant by that sentence was that the planned kneewall (or knee wall) in the upper floor is not absolutely necessary.
I don’t know if it’s still possible to add an attic in the upper story with the current plan, but that could be an alternative.
And what do you research when it comes to a utility room? For example, by asking Google how large a utility room for a single-family house with a heat pump should be, and then looking at several manufacturers' websites. But I’ve already realized that I need to look into this topic more carefully.
Thanks again for linking the other article.

The storage room behind the garage is planned as a basement substitute; it is 2 square meters (about 22 square feet) larger than our current basement. Of course, you can’t expect huge improvements, but—drumroll please—cordless screwdrivers, drills, etc. (Bosch and Festool case systems, greetings) fit very well there.
Also, by this I meant that the planned knee wall in the upper floor isn’t absolutely necessary.
I don’t know if it’s still possible to add an attic space in the upper story with the current plan, which might be an alternative.
And what do you research regarding the technical room? For example, by asking Google how large a technical room for a single-family house with a heat pump should be, then looking at several manufacturers’ websites. But I have also gathered that I need to take a closer look at this myself.
Thanks again for linking the other article. Please note that unlike a basement, you cannot store anything frost-sensitive in this storage room. So paint, silicone, adhesive tapes, batteries, flower bulbs… must be brought inside the house during winter (and not to the attic).
