Hello everyone,

My father lives in a house on a plot of about 1050m² (11,300 sq ft) located in a town east of Cologne. Since building plots are very scarce here and the prices correspondingly high (land value index ≥650€/m²), we have decided to build another house on his property. We are considering constructing it to the west of the existing building. An informal inquiry with the city referenced §34 (there is no zoning plan) and was answered with "generally seems feasible, legal clarification through a building permit pre-application or approval planning."

Regarding the pictures: north is aligned with the top edge of the plan.

The separated parcel would be about 410m² (4,410 sq ft) in size. Access would most sensibly be from the street to the south. In light blue, I have marked a potential building area, with a 3m (10 ft) setback from the northern neighbor, 3m (10 ft) from the assumed boundary to my father’s property, and 3m (10 ft) from the street to the south (which is a dead-end).

Should I go directly to an architect for the building permit pre-application, or is there a way to proceed effectively on my own? I am currently quite inexperienced when it comes to building matters. If you have any ideas on how to position things on the plot, I am open to all suggestions. The only thing I would prefer to avoid is placing a garage directly on the property line next to my father’s house.

Thank you very much for your input.

Budget is missing.
And regarding §34, there is no information about the neighboring buildings (modern flat-roof house / pitched roof).
You don’t have many options. Just try placing a 10 x 10 meter (33 x 33 ft) structure on the plot. That won’t work.
I would go with an L-shape on the ground floor and build part of the second floor above it (attic/upper floor). That way, the garden would face southwest.

Regarding the boundary garage: a boundary garage is less problematic than a two-story building that you want to build to the west in front of the parents’ garden.

Is the picture labeled "Environment" not sufficient for you? I find it quite informative.

Yes, it is. Thank you. I hadn’t loaded that picture, only the first one with the dimensions.
