Hello dear forum members,
after reading along for a long time, the time has finally come for us as well.
Since we are always open to criticism, different perspectives, and suggestions, we look forward to your opinions on our floor plan design.
Before entering the crucial phase, the two of us created a self-designed floor plan, and this is the one we want to move forward with.
Now, onto the details:
Development Plan/Restrictions
Plot size: 880m² (0.22 acres)
Slope: Approximately 2m (6.5 feet) between the east and west property boundaries but varying significantly—see surveying documents
Floor area ratio: 0.4
Gross floor area ratio: 0.8
Building envelope, building line and boundary: 13x10m (43x33 feet) for one full story and 10x10m (33x33 feet) for two full stories
Edge development: None
Number of parking spaces: No requirements
Number of stories: 2
Roof type: According to the development plan, pitched roofs are mandatory
Architectural style: Urban villa
Orientation: Main entrance on the east side, terrace and recreational garden on the west side, utility garden on east side
Maximum heights/limits: According to the development plan no specification other than two full stories
Other requirements: Rainwater must infiltrate the plot. According to the soil report, the ground is not optimally permeable. Additionally, some hydrostatic pressure from groundwater is expected. Therefore, we plan to install a cistern to use rainwater.
Client Requirements
Style, roof type, building type: Solid construction (Ytong), 35cm (14 inches) hip roof with 80cm (31 inches) knee wall
Basement, floors: Basement 10x10m (33x33 feet) precast waterproof concrete basement (white tank construction)
Number of occupants, age: Parents 36 and 33, children 3.5 and 1.5 years old, plus one due July 2021
Space requirements on ground floor and upper floor: Ground floor 80m² (860 sq ft), upper floor 80m² (860 sq ft), attic 15-20m² (160-215 sq ft), basement mainly utility but with a larger fitness room planned
Office: Family use or home office?: Home office only. Before COVID-19, working at home 2-3 days a week; in 2020 a total of 10 months working from home; after COVID-19 probably 3-4 days a week home office
Overnight guests per year: 5
Open or closed architecture: Open on the ground floor
Traditional or modern construction: Modern
Open kitchen, kitchen island: Open with large kitchen island, cooking happens daily, about once a month guests up to 8 people, pantry directly adjacent to kitchen
Number of dining seats: 6-8, expandable with an additional table
Fireplace: No
Music/stereo wall: No
Balcony, roof terrace: No
Garage, carport: Large garage plus possibly 1-2 guest parking spaces
Utility garden, greenhouse: Yes, large greenhouse (possibly earth-sheltered) planned on east side with south orientation
Other wishes/special features/daily routine, also reasoning why certain things should or should not be included: Very bright ground floor with many windows, where only the middle lift-and-slide door and the door near the kitchen can be opened, all other windows on the ground floor are fixed glazing. Photovoltaics and KNX home automation system are planned.
House Design
Who created the plan: DIY
What do you especially like? Why?: Large living/dining area, open kitchen, pantry, three children’s rooms roughly equal in size facing the garden
What do you dislike? Why?: No walk-in closet in the master bedroom
Price estimate according to architect/planner: 400,000 without additional construction costs
Personal price limit for the house including equipment: 415,000
Preferred heating technology: Geothermal (either probe or trench collector) with underfloor heating
If you had to give up, which details/extensions
-could you do without: Walk-in closet in the bedroom
-could you not do without: Large living/dining area, open kitchen, pantry, three children’s rooms roughly equal in size facing the garden
Why is the design the way it is now?
This is the 12th or 13th version after long discussions and considerations. Whether it is more or less final also depends on your feedback.
What is the most important/basic question about the floor plan summarized in 130 characters?
Optimally use space and layout, avoid pitfalls.

The office was planned on the top floor (attic) but moved down to the basement, and now we need to make sure the slight slope of the site is used optimally. So much for the idea that we wouldn’t be open to other opinions 😉 Kraj schrieb:
According to the architect, these are the regulations: building envelope 10x10 meters (33x33 feet) for two full stories, or 10x13 meters (33x43 feet) for a stepped roof design. With the 10x13 meter envelope, only one full story is allowed; however, on the upper floor (first floor), a full story can again be built within a 10x10 meter (33x33 feet) footprint.
We were advised to either extend the basement to 10x13 meters (33x43 feet) to build the stepped roof design or keep both the basement and the building within the 10x10 meter (33x33 feet) building envelope. Since I don’t quite understand the whole thing and the basement is a fixed requirement for three children and the slope, I’m throwing out a spontaneous idea: use the upper floor as the children’s level, and the basement/lower ground floor as the parents’ living space—that is, besides the utility room and storage, have an office, bedroom, and small shower bathroom in the basement, and integrate the hobby room with the children’s bedrooms upstairs.
As long as the children need care during the night, the hobby room could temporarily serve as a bedroom.

... Are your pipes located in the precast hollow-core slab? If I use round pipes, I would place them inside the hollow-core slab and provide openings right away to avoid later core drilling, chiseling, and similar work.
Thanks for the tip about the Brady labels. Are those the self-laminating ones? ... Well, you’re quoting the text where it’s already mentioned 😉
The controlled ventilation system pipes are located on the ground floor within the floor structure (25cm (10 inches)) and on the upper floor, the controlled ventilation pipes are in the knee wall of the attic.
And yes, the Brady labels are self-laminating.
By the way, my house construction thread includes pictures of the installed valves (from the outside).

If I use round pipe, I would embed it into the prefab concrete slab and provide the openings in advance to avoid core drilling, chiseling, or similar work later on. Even if the pipes are placed on top of the slab instead of inside it, you should plan the outlets before pouring the concrete (by installing a DN100 pipe). This approach is definitely cleaner and easier than core drilling afterwards.

As long as the children need care at night, the hobby area could temporarily serve as a bedroom. Thanks for the suggestion @ypg, we hadn’t considered that option yet and it might make sense. The only thing is that we wouldn’t move the small shower bathroom from the ground floor to the basement, because then we would need a lifting station again.

Well, you’re literally quoting the text where it says so 😉
The controlled mechanical ventilation pipes run in the floor structure of the ground floor (25cm (10 inches)), and in the attic they run inside the knee wall.
And yes, the Brady labels are self-laminating.
By the way, in my house building thread there are pictures of the installed valves (from outside).

Thanks for the link, your house turned out really nice by the way.

That’s definitely cleaner and easier than doing core drilling afterwards. You’re right. Once the ventilation planning is finalized, we will know where each pipe needs to go and can then plan the DN100 pipes before the concrete pour. Thanks.
