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.

knalltüte27 Dec 2020 19:26I just read that a rainwater cistern is also included. It costs around 5,000 USD for approximately 5-6m³ (cubic meters) (around 176-211 cubic feet), including the rainwater system/pump and excavation/installation.
I really don’t see how you can stay within the budget with all these requirements 🙁 Or are you building in a very cheap development area (East?)
Please share which state/region and the approximate location...
I also saw something about a 2m (6.6 feet) height difference 😱
How many centimeters (inches) of elevation difference are there within the building plot?
There is a "golden" rule for this, I think it was established by @11ant; it might apply here (plot “forces” a basement or something like that :cool 🙂

Then don’t just show draft 12 or 12a here, but also the development history – at least draft 1 and the reasons why the drafts 2 to 11 were not final yet, including any shortcomings or revised planning goals in the requirements specification. Otherwise, you’ll just get a bunch of suggestions here that you already planned and discarded, and risk being accused of ignoring advice. Maybe someone will experience a “we recognize ourselves” moment while browsing through the thread https://www.hausbau-forum.de/threads/grundrissoptimierung-stadtvilla-aufschuettueberlegung.33680/ 🙂 The first draft is over 1 year old. At that time, we planned only 2 instead of 3 children’s bedrooms. The further changes were mainly related to the basement, attic conversion, bathtub on the upper floor, etc. The basic layout at least on the ground floor has hardly changed.

Are the costs for geothermal energy already included in your price estimate? Honestly, I would be surprised. We briefly considered it ourselves but dropped the idea due to the drilling costs, which were quoted to us at around €90,000. Yes, these costs are included, and €90,000 for a geothermal borehole sounds very high to me. €9,000 would still be high but justifiable depending on soil conditions and location. As superzapp already explained the horizontal loop collector, we are planning a geothermal heat pump (from Nibe) with a horizontal loop collector. Installation of the loop collector will be done entirely by ourselves. Estimated costs including the heat pump are €16,000.

But isn’t that price estimate without the basement? No, actually it includes a 10x10 m (33x33 ft) waterproof basement.

Where is the street located? Will any trees be cut down?
Can you provide some dimensions? I know the software, and to my knowledge, this standard staircase (or any other staircases from that software) is not worth mentioning and must be adjusted in size.
Four bedrooms on 10x10 m (33x33 ft) is not really optimal room sizes. It’s not possible to have three equivalent rooms on 9.20 m (30 ft) – as you can see. How wide is the bottom plan? 2.60 m (8.5 ft)? 2.45 m (8 ft)? Also, you lose living space next to the door.
How wide is the bathroom? 1.60 m (5.25 ft)? How long is it in total? 7 m (23 ft)? What happens if three people are in there at the same time? Traffic light system? Just joking, but seriously: with the necessary pre-wall installations, the bathtub’s position is not even justified there.
How wide is the pantry? One meter (3.3 ft)? How is a freezer approximately 60 cm (24 in) deep supposed to fit there, and how shall you design the other walls?
I find the floor plan anything but final – it’s a draft that shows 3 rooms fit only moderately on 10x10 m. The next step should be to give up on 10x10 m.
I consider the budget too tight, especially with a living or heated basement.https://www.hausbau-forum.de/attachments/grundrissplanung-unbedingt-vor-beitrag-erstellung-lesen-79977-1-jpg.10450/
Minimum stair dimensions... The floor plan is oriented north, main entrance from the east, and all trees will be cut down within the next 4 weeks.
Thanks for the hint about the stair dimensions, we had not noticed that before. The staircase from the software measures 192 mm (7.6 inches) width, 201 mm (7.9 inches) depth, and 275 mm (10.8 inches) height (Note: These are presumably cm, so corrected below).
Correction: The staircase dimensions are 192 cm (75.6 in) width, 201 cm (79 in) depth, and 275 cm (108 in) height.
We will adjust to 230 cm (90.6 in) width and 230 cm (90.6 in) depth.
I have also added further dimensions for the rooms on the upper floor.
The pantry is exactly as wide (105 cm (41 in)) as our current one; a single-sided shelf with 15 cm (6 in) depth is sufficient there. See an example in the attachment, where the access is also directly from the kitchen but the pantry is significantly wider than ours.

The floor plan is good, but I would reconsider the pantry. Try furnishing it. More than a narrow shelf won’t fit. You do have a basement, though: so drop the pantry, enlarge the kitchen, and add more windows to that side (e.g., a high horizontal window band in the kitchen can be great).
Where is the home office or desk area? We want the pantry close to the kitchen since we cook daily, but if it ends up too tight, we do have the basement, you’re right. The home office is located on the attic floor.

Aside from the bathroom, I like the floor plan. Unfortunately, I can’t “read” the plot; will the basement be partially above ground? The budget for 180 sqm (1,938 sq ft) plus basement seems very tight to me. The basement might be about 30 cm (12 in) above ground level; we still need to confirm this with the architect.

What does “including equipment” mean? Painting, flooring, kitchen? Including painting and flooring.
Excluding furniture, kitchen, and garage.

I really don’t see how you can keep the budget with all these wishes. Are you building in a very cheap development area (east?).
Tell us which state and approximate location ...
I also read about a 2-meter (6.6 ft) height difference 😱
How many centimeters of height difference are there within the building plot?
There is a “golden” rule, I think established by @11ant; it might apply here (plot “forces” a basement etc. :cool 🙂 Yes, there is actually a 2 m (6.6 ft) height difference from the driveway in the east to the property boundary in the west, and we are considering using the basement excavation material to build up the plot. However, we would have to contain it at the boundary and also adjust the fencing. We have not made a decision on this yet and would welcome suggestions. The golden rule from @11ant is being implemented 🙂

At least €100,000 are missing in the cost estimate. AT LEAST. Yes, you are certainly right; with a general contractor, these requirements are definitely not achievable within the budget.
We are building in NRW and will do a lot of work ourselves, including:
- Bricklaying all exterior and interior walls with 2 friends
- Installing the horizontal loop collector
- Installing the underfloor heating including insulation but without screed
- Installing ventilation ducts for the ventilation system
- Chasing and laying electrical and bus lines for KNX
- Installing all floor coverings
We are aware this is a huge amount of self-performance and will only work thanks to parental leave/parental benefits and generous support.
Thanks for the feedback so far and we welcome further comments.

Yes, they are included, and 90,000 for a geothermal drill sounds very high to me; 9,000 would still be high but reasonable depending on soil conditions and location. As superzapp already explained about the horizontal ground collector, we are planning a ground source heat pump (from Nibe) with a horizontal loop collector. The installation of the horizontal loop collector will be done entirely by ourselves. Estimated costs including the ground source heat pump are 16,000€ (approximately). We would have needed about 600 meters (yards) of drilling (620 sqm (square meters) floor heating = semi-detached house with heated basement). Only 60 to a maximum of 70 meters (yards) drilling depth would have been approved. So 9 to 10 boreholes, and that would be so expensive. My upcoming two air source heat pumps with storage and installation cost 52,000€ (approximately). Compared to that, the 16,000€ sounds very, very reasonable.
