Good morning and thank you . I spoke with the LRA yesterday. I had to think of statement "You have a pharmacy-only plot." Nothing about it is simple, as is often the case with nice things :D but the LRA is really cooperative and gives us good advice. His tip is also that I should build more compactly so that they give me the necessary exemptions. We tend more towards the more compact version, so 3 floors. This leads to 2 issues:
1. If I put the basement directly under the ground floor, it’s not allowed because I exceed the maximum wall height.
2. However, if I offset the basement, it’s also not allowed because I exceed the maximum width :D Actually! Under certain conditions, they would exempt me from that (see below). I need another exemption from the forestry office because the forest distance on the east side cannot be maintained.
Response from LRA
"Regarding the wall height exceedance, it makes no difference to us whether the garage as part of the building or a granny flat is located in the basement. An exemption of about 1.00 m would be conceivable from our point of view if there are compensatory measures (green roof, basement visually and structurally separated) that reduce the effect of the wall height. Furthermore:
The wall height may be exceeded by max. 1.00 m on 1/3 of the building length.As the development plan represents the planning intent of the municipality, the consent of the municipality is required in any case.
Regarding the exceedance of the building width, we can only make a statement if the dimension of the exceedance is specified and it is clear over which length the maximum width is exceeded.
An exemption from the forest distance can be granted if an atypical case is present. Since a site with poor growth is assumed, an atypical case exists. The minimum distance that must ultimately be maintained to the forest must be clarified with the forestry authority."
The LRA asked me in advance to visualize how we imagine it; I made a quick sketch during the lunch break.
Today at 2 pm I have an appointment with the planner; let’s see what he thinks.
One question about the material to the group: we want thick, uninsulated (exterior) walls made of lightweight expanded clay aggregate, if possible without a ventilation system (if necessary, then with one). But how about the interior walls regarding sound transmission, moisture, drilling, hammering nails into the wall, etc.? Your opinions on that would help us a lot. Lechner Massivhaus would provide the whole house, Kastell only the shell, we haven’t found other providers for our region yet.
If we get feedback from the requested providers, we can alternatively use Poroton bricks, but I am a bit skeptical because I know too little about them.
