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.

What is the most important/basic question about the floor plan summarized in 130 characters?
Optimally use space and layout, avoid pitfalls.
Where exactly will the road be? Will any trees need to be cut down?
Could you provide some measurements? I am familiar with the software, and as far as I know, the standard staircase model (or any other staircases in this program) is not very accurate and always needs to be adjusted in size.
Four bedrooms within a 10 x 10 m (33 x 33 ft) area does not create optimal room sizes. Trying to fit three equal-sized rooms into 9.20 m (30 ft) is not feasible, as you can see. How wide is the lower part of the floor plan? 2.60 m (8.5 ft)? 2.45 m (8 ft)? Moreover, a living area is lost at the door.
How wide is the bathroom? 1.60 m (5.3 ft)? How long is the whole bathroom? 7 m (23 ft)? What happens if there are three people using it at once? Traffic light system? Just kidding, but seriously: with the necessary wall installations, there is not even space for the bathtub where it is currently positioned.
How wide is the pantry? One meter (3.3 ft)? Where is a freezer about 60 cm (2 ft) deep supposed to fit in, and how can the other walls be designed around it?
I find the floor plan far from final or anything like that—it is a draft that clearly shows three rooms barely fit on a 10 x 10 m (33 x 33 ft) footprint. The next step should be to give up the 10 x 10 m (33 x 33 ft) dimension.
I also consider the budget too low for a living basement or a heated cellar.
Minimum dimensions of staircases...

The floor plan is good, but I would reconsider the pantry. Try furnishing it first. More than a narrow shelf won’t fit in there. You do have a basement, right? So I’d suggest removing the pantry, enlarging the kitchen, and adding more windows on this side (for example, a high horizontal window can also look great in the kitchen).

The plot size is 880 sqm (9,470 sq ft), is that enough? We were advised against a horizontal ground heat exchanger, even though the plot is large enough, saying it would be too ineffective. The plot size is more than sufficient! And there are hardly any more efficient systems than a horizontal ground heat exchanger. However, very few plumbers have experience with it since it is not very common, and those who do often install it themselves. You definitely need to research thoroughly; there is a forum dedicated to this. There are some conditions that will likely be well met here. Have the heating demand calculated (general contractor/building contractor/energy consultant?). In that forum, you will also find a suitable tool (Trenchplanner) linked, which allows you to calculate the horizontal ground heat exchanger yourself after some practice. Rent an excavator and try to do as much of the work yourself before construction starts (if possible). Of course, find a plumber beforehand who can connect the ground heat exchanger to the heat pump. For comparison: Our 220 m (720 ft) borehole (2x110 m (360 ft)) was supposed to cost about 12,000 euros. The horizontal ground heat exchanger will be surely less than half of that if you do it yourself, even when renting an excavator (about €40/hour) plus operator.
Unfortunately, as I realized “too late,” there are a few gaps in the planning. It’s impossible to plan everything perfectly on your own simply because the knowledge is lacking. So, it’s definitely worth handing over some tasks to trusted tradespeople. 😎
