So, it took a little while, but here comes the name of the development plan: Development Plan Baublock Mitteltor-, Alte Friedrich-, Teutschneureuter and Pfarrer-Graebener-Street. You can find it if you search for Geoportal, Karlsruhe and development plan and then look for 819 in this portal. There you will also find the plan drawing etc. The thing about the semi-detached house sounds dangerous. What exactly would that mean? Would you basically have to build like the neighbor? Meaning dimensions, type of construction, etc.?
It is not my intention that people have to "pull everything out of me" ;) Regarding my sketch: All 3 continuously outlined areas stand for existing houses. Only the striped area stands for the corresponding building plot. The left 2 buildings belong to the neighboring property. Regarding the prices, it is very simple, these are completely unprofessional rough estimates from my side. Since I have no offers, experience values or anything like that here yet, I hoped to get a little more info about the meaningfulness of the estimation :) According to the development plan only open development is allowed. However, there is an old building permit for a very small house at this location that is approved. This was about the full width (9.5m), but only the rear 7.5m of the 12 possible. Based on this I estimate that a) there is no semi-detached house obligation and b) you may build directly next to the neighbor?!
Very strict. So far no buffer calculated :(
Those are good thoughts! Yes, maybe in our case a basement really doesn’t make that much sense, especially from a financial point of view. A small workshop could perhaps really be realized on the ground floor with a door leading outside. Then the house would have to be somewhat larger than 120m² to have space for the technology, small office and workshop... We definitely would need an almost finished house. I thought a shell house was something like that, but I was probably mistaken. Of course, a used kitchen also costs money. Regarding furniture, I’m not worried because we rather have too much of it ;) We also already have garden tools. I will try to make an updated version of my cost estimate without basement and with the missing items as soon as I have more info about the foundation slab. Regarding ancillary facilities the development plan says:
Ancillary facilities are only permitted within the buildable areas of the property. On the building plots, only one pergola, garden shed or dish hut with a maximum volume of 10 m³ is permitted per property as ancillary facilities. Terraces may not exceed the building boundaries.
How much does a simple foundation slab including earthworks cost approximately?
