Dear house building forum members,
I am new here and would appreciate creative ideas, opinions, and suggestions regarding our building plot:
Our plans:
Our goal is to build a spacious single-family house (220-240 sqm (2,370-2,580 sq ft)) with a separate apartment (about 60-70 sqm (650-750 sq ft)) for two adults and two small children.
It would be ideal to have a wide/long double garage plus two additional parking spaces in front.
One full floor (plus basement and attic) according to the development plan.
Style: open, modern, minimalist but without extravagant or unnecessary luxury.
Of course, good privacy from neighbors is very important.
Plot size: approx. 920 m² (approx. 7,860 sq ft) = approx. 730 m² (7,860 sq ft) plus approx. 190 m² (2,045 sq ft) driveway.
Development plan:
Site coverage ratio (floor area ratio): 0.3
Gross floor area ratio: 0.5
Open building style
1 full floor
Gable roof 28-38°
Knee wall max. 0.8 m (2.5 ft)
(see attached images)
Additional information / my thoughts:
– Nice plot in Baden-Württemberg with private access road (see photos attached)
– West edge: adjacent to open fields
– Not entirely flat: about 1 to 2 m (3-6 ft) height difference from west to east; sloping downwards to the east
– Plot width (north-south) is 20 m (66 ft).
My questions:
1. Do my plans for the size of our desired house fit within the development plan? Can I build about 300 m² (3,230 sq ft) (house plus separate apartment) there?
(Sorry for asking so simply for reassurance. Based on my calculations and my understanding of site coverage and floor area ratios, it should be possible.)
2. How do you assess the situation? Will it feel relatively “tight” in relation to the two neighboring houses (north and south)?
Theoretically, quite large houses can also be built there according to the development plan (see photos attached).
I know this is a high-level concern, but at this early planning stage, I would like to get your valued and experienced opinions.
For example, where to best position our house within the building zone to be as “safe” as possible, regardless of where and how neighbors may build.
The goal of this discussion at this point is not to develop detailed floor plans, but rather to collect initial assessments and ideas about the best way to build on this plot.
Thank you very much in advance!
If further information is needed, I’m happy to provide it!
Thanks in advance and best regards!

Thanks for your thoughts!!!!
What should I understand as a layperson? Sorry – do you simply mean the “spatial effect” or how the room feels?
Best regards and thanks!!!

j.bautsch25 Sep 2019 12:32Yes, the spatial effect is what is meant. If your room is very large (m²) and the ceiling is very low, the room feels cramped and not truly spacious. The opposite can be seen, for example, in small, narrow rooms. If these have very high ceilings, as is often the case in older buildings, they appear disproportionately tall and tunnel-like. So, it is important to find the right balance between room size and ceiling height.
Exactly as j.bautsch summarized it. Given the (huge) size, there is a risk that the rooms will feel very cramped with a standard ceiling height. Therefore, it is crucial to pay attention to the height! Alternatively, consider scaling down and designing the house to be a bit more compact – this saves money and also creates a cozier atmosphere (after all, who wants to live in a ballroom).
Dear forum members and experienced builders,
Here is our most recent design (just before submitting the building permit / planning permission application).
Main changes:
- We have now included a separate apartment (hence the stairwell structure on the southeast side).
- Various smaller floor plan adjustments
Anyone who would like to take another look is warmly invited.
Many thanks again for all your ideas and suggestions.
Best regards and wishing you all the best
