Build an affordable prefab house on expensive building land

Yeah, that’s quite a statement

Wouldn’t it also be missing how many square meters you’re supposed to get for that?

Basically yes

But in the photo it didn’t look very big (estimated 5-600 sqm)?

Maybe I also greatly misjudged :)

Hello!
My boyfriend and I have the opportunity to purchase a building plot. However, it is quite expensive and awkward to build on due to the required distances (triangular). Therefore, ideas, suggestions, possibilities would be very helpful for us to make a decision. For example, prefabricated house, etc... thank you
Photo of the floor plan with the distances

So... again, before we move on to the third page and no question can be answered:

more interesting than the distances are the measurements between the distances, namely the building zone itself. These numbers are necessary in order to make any proposal :)

If one wanted to build something rectangular, I would estimate about 5x10m (+-), which would fit into this triangle. Quite a difficult measurement. Is the price level of the property particularly favorable for the location?

The location must be exceptionally good for one to even consider building there. You basically have to place the house directly on the border, and even then it is very small if it is to be rectangular. Do you still have space for a garage/carport/parking space? Where is the property access at all? Is the plan oriented to the north? If yes, then you have your garden in the north, obscured by a large building to the west and your house in the south. Only a narrow beam of sunlight comes in there. If the plan really is an adjacent development on the border, then you are not allowed to put windows there. A house without windows facing south, or relatively few facing southwest, would never be an option for me. This would also make life difficult and thus expensive for you regarding the energy saving ordinance and KfW standard.

Clear thing. A triangular house from the architect is needed. :)
