No information from the building authority to the property owner

Now it would only sound like this: 1,100 sqm plot, fully developed, period.

§ 34: You may build as customary in the neighborhood (my interpretation). Alright. The plots are between 65 and 80 m deep. One built quite far forward by the street with a large garden at the back, another more in the middle with gardens in front and back, yet another has his house in the rear third with a lot of garden towards the street. So I would consider the building window to be “from the frontmost house” plot a to “the last house” plot b with the respective boundary distances. Mostly 1.5 stories, but also two houses with two full stories. Crosswise and lengthwise, the ridge direction thus partly turned 90°. So from-to.
A semi-detached house, otherwise all single-family houses, partly with many sheds.
That will be exciting.

I consider in advance what problems may arise

Damn, you were faster with the answer

The problems are the interested parties, not the property…

Just take a look at how properties are described on Scout. Either with very specific planning (for exactly one possibility), with indication of floor area ratio/site area ratio, with a general statement “preferably with a preliminary approval for a single-family house or multi-family house” or finally with the note construction preferably 34.

You have to decide what you want. Not everything is possible at once. It naturally also depends on the property itself, the location, and the demand.

Is a property in North Saxony desirable or expensive?
