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

First, I want to do some preliminary planning,1. Start with the zoning plan/34er to find out the legal possibilities for the plot.2. For the 34er: Check the surroundings via Google to see how much area can be built upon.
3. Old house plan: determine where an extension could be added.
2a/3a. Assess the needs for parents and your own family.
4. Planning can begin.

Christian_p18 Mar 2021 19:40Good evening everyone,
there are quite a few replies in one day, now I finally have time to read and respond calmly.
@Tassimat: Of course, I will do that as well. I just want to gather some ideas in advance to evaluate the project in the first place.
The sketch is actually based only on a rough measurement, as long as I don’t have the official plans.
@icandoit: Thanks for the offer, but unfortunately I prefer not to write that in a forum.
I can’t send private messages yet (too few posts), otherwise I would do that.
In almost all municipalities, I can see the yellow outline with the designation, but when I click on it, nothing happens—not even in cities like Nuremberg or Bamberg. Do you just have to click on the area? Or maybe you have to register?
@ypg: You’re absolutely right, but sometimes impatience just gets the better of me ;-)

You are of course right, but sometimes impatience is just a bit too strong ;-) Sorry, but there is no other way. You need to know what is allowed. Otherwise, it can quickly become a waste of time. You might get lost in a plan that will never be approved or built. This is not a playground after all 😉
Your impatience should focus on being able to answer point number 1 first.

Christian_p18 Mar 2021 19:52@ypg Yes, I’m working on it. If it doesn’t work online, then maybe tomorrow by phone or email.
I can only plan properly once I have all the information; until then, it’s just “brainstorming.”

Christian_p23 Mar 2021 20:17Hello everyone,
I have gathered some more information now.
The first image shows the current status, with only minor deviations in scale.
In the upper floor, the knee wall is about 600mm (24 inches) high, there are three rooms, one bathroom, and a storage room.
The exterior walls are 30mm (1.2 inches) thick, the interior walls 115mm (4.5 inches).
The ground floor slab is solid, and between the ground floor and upper floor there is a wooden beam ceiling.
The ground floor currently has a bathroom, pantry, kitchen, dining room, and living room; however, it still needs a bedroom. The upper floor currently has three rooms, a bathroom, and a storage closet. Since it is intended to become a separate apartment, it is identical to the ground floor, and the attic shall be converted into three bedrooms with a bathroom. To provide enough space for all, I would like to carry out the following modifications:
1. Extension over the ground floor and first floor to add one additional room on each floor (no basement). The second floor (attic) would have a balcony.
2. Possibly an additional extension on the ground floor for a study / conservatory. The first floor would also get a balcony.
3. Raising the roof (with less pitch?), so that three bedrooms with a bathroom and storage room can be created in the current attic.
Since the house has a shared staircase, everything should be planned so that it can be divided into three separate apartments if needed.
Attached is also an image showing roughly how I envision it.
Development plan:
According to the responsible municipal official, this is not an issue here. All neighboring houses are significantly taller and also have various roof types.
Do you perhaps have other ideas or have you done something similar before?
Thanks in advance for your feedback.
Best regards,
Christian
