ᐅ Extension to an Existing Multi-Family House – Setback Requirements from the Property Boundary?

Hello,

I have the opportunity to extend the existing house of my grandfather. His house is approximately 13.5 meters (44 feet) long, 9.75 meters (32 feet) wide, and 11 meters (36 feet) high. The side intended for the extension is designed as a fire wall, as the original plan was to basically add another part to the house. However, this was never realized.

What should definitely be possible is to complete this extension now, but it is too large for my needs. Additionally, I would like to have a garage.

Therefore, my plan is to build the garage as a boundary wall structure and then attach my residential building to it, which would be roughly square in shape. Moving it further away would be difficult, as the property boundary would end at some point. In my opinion, an advantage would be that the upper floor could have windows again, which may not offer a particularly nice view but would at least provide some natural light.

The development plan allows for 3 full floors. I would prefer to build a 1.5 to 2-story structure, with a height of about 7 to 8 meters (23 to 26 feet).

Are there any opinions on this, especially regarding legal building regulations? The applicable law is in Lower Saxony. I can upload pictures or plans later, I’m just on the go right now.

Thanks in advance for the input

To warm this up again:
This project would be best managed by:
  • Architect
  • General contractor
  • ???
  • A combination of 1, 2, and 3 in varying proportions?

If the "Three Investigators" you’re referring to are not the above-mentioned persons but rather someone from my professional field, my answer would be:
95% 1st and 5% 3rd. The general contractor is usually managed by the architect. However, first we need to clarify what you mean by “managed.”

I hadn’t considered the audio drama heroes but was rather thinking of other professional groups that might be helpful.
Which profession do you belong to?
By supervision, I meant at least the project phases 1-4, as there seem to be different variations regarding how much "service" or hassle one would like to have afterward. The @11ant believes that the person who does the planning should also take on construction management but not the construction work itself. Have I understood that correctly? That would then argue against a "draftsman" of a general contractor.

Surveying.

Definitely. Complex planning law and unclear building regulations call for an experienced architect. What makes sense after obtaining the building permit/planning permission depends on the specifics of the project and how complex the execution will be.

The land registry office has been commissioned to subdivide the property (subdivision was not possible), and the notary is also involved and doing their part.

So, let’s see who is considered competent around here.

I don’t think I said it exactly like that. Construction drawings follow the design planning, should develop from it, and in my view are always best done by the same planner. The same applies to site management: having "the conductor as the same person as the composer" guarantees the most faithful interpretation. These three stages belong together. A site manager employed by the contractor, however, has a different role: while avoiding defects is also part of it, this comes from a different perspective.
