ᐅ Extension and Vertical Addition to a 1965 Existing Building

Hello everyone,
my name is Christian, and I have been reading this forum for some time now. Since my plans are becoming more concrete, I am now making my first post.
I have the opportunity to take over my parents' house, and they would continue living there.
The house dates from 1965 but does not offer enough space for all of us, so I have the following ideas, always assuming that the renovation is approved. Of course, I will ask for permission before detailed planning, but for now, I need some help brainstorming.
The house currently has one and a half stories plus a basement. The basement ceiling is about 1 meter (3 feet 3 inches) higher than the garden, and the knee wall on the upper floor is about 1 meter (3 feet 3 inches) high, resulting in a noticeable roof slope.
The ground floor, which would serve as a separate apartment for my parents, currently has a kitchen, pantry, living room, dining room, and bathroom—unfortunately one room too few, so an extension here would be ideal.
If there is going to be an extension, ideally it would be two stories to create an additional room upstairs as a study or guest room. The extension would best be attached to one of the two gable ends (approximately 9 meters (30 feet) long). A timber extension would appeal to me.
However, to ultimately create the desired space for our family of four, an additional story would also be necessary. I am considering either a flat roof or a hipped roof so that another floor with a bathroom and three bedrooms can be added without much increase in height. Currently, there is an attic above the upper floor that is about 2.5 meters (8 feet 2 inches) high in the center, but in its current state, it would only provide space for a bedroom and bathroom at most.
Regardless of approval and structural considerations, I have the following questions:
1. Since the basement protrudes about 1 meter (3 feet 3 inches) above ground level, a quite high foundation would need to be built for the extension to align with the existing floor level. Would it make sense, for a bit more money, to also have a basement under the extension?
2. Does anyone have experience with how an additional story with a new roof might look in this case? Would the roof with the attic be removed down to the knee wall and rebuilt? That would mean removing all interior walls on the first floor as well?
3. Does anyone possibly have other suggestions on how to realize this?
An extension along the side wall would also be possible, but that would reduce the garden space in the area where it is most used.
For better understanding, I have attached a 3D sketch, although it is not yet fully to scale.
Thanks in advance for your advice,
Christian

Christian_p18 Mar 2021 10:39Thanks for the information. Could it be that this only works in cities or similar areas? Or where can I find this? Do you have an example of where I can find it?
Thanks in advance.
Thanks in advance.
Open Bayernatlas, click on "Change topic" in the menu on the left --> select "Planning and construction" --> then click on "Development plans Bavaria" --> search for your location --> a yellow outline indicates a development plan. Usually, the plan is available when you click on it. We are also in a small village setting, and everything is included here (market community).
Edit: it is also possible that there is no development plan for your street and the building regulations follow the neighborhood development rules according to §34.

The neighborhood in older residential areas is always a good indicator of what might be feasible for you: Are there already houses nearby that have been extended upwards? Are there houses with flat roofs in the area?
Your questions cannot really be answered without knowing the house better. Please upload floor plans and cross-sections here.

3. Does anyone perhaps have another idea on how to realize this?
Christian_p schrieb:The 3D "sketch" doesn't seem to reflect that. Is the roof very steep?
The house currently has 1.5 floors with a basement

Currently, above the upper floor there is an attic, which is about 2.5 m (8 ft) high in the middle

Online, I can’t find any zoning plans. When I click, only a window appears titled “Object Information” with no further details.
I have also checked other randomly selected municipalities and found nothing. Either I’m searching incorrectly, or such plans exist only for a few municipalities, or even just for new development areas.
It is a mixed-use area with different types of buildings: single-family houses, multi-family buildings, industrial halls, etc. I will simply contact the municipality directly, and then I will know for sure.
