The new house will again be attached directly to the existing neighboring half.
The plot measures 1,027 sqm (about 11,060 sq ft), and the design comes from my architect.
I would appreciate honest and constructive feedback on the floor plan and room layout.

Could it be that it needs to align with certain points of the neighboring house? The existing old building as well as the neighbor’s property have a prominent basement, a main floor, and above that a small attic with a loft, totaling around 45sqm (480 sq ft) of living space. The new building, however, is planned to have only a ground floor and one upper floor. Of course it has to align with the other detached house, since the house needs to connect with the roof pitch, ridge height, and eave height where it is currently attached.
I get the feeling you haven’t really been on this street yet or maybe have only driven past the house you bought once or twice. There are dozens of houses here, all originally very similar, lined up in a row. Most have already been remodeled. But you can quite clearly see the path a renovation (or rebuild) must take. If I had bought this house on the 1027sqm (11,048 sq ft) lot, I would have first visited all the houses on a Sunday and talked to the residents before even submitting an application :P
Personally, I am really interested in the history of these houses. Not that I have nothing else to do, but some things are so fascinating that you like to dive into them.

For me, the location and the permitted building rights were the most important factors at first. I wanted to know exactly what area I was allowed to build on and how many square meters would realistically be possible in the end. I didn’t find any property nearby that was comparable in size. However, I was aware that you basically have to adapt to the existing surrounding structures.

Please share some photos of the existing building. The street view of the design looks quite unusual. What does the zoning plan say about roof extensions?I will send you the other documents I have later. Thank you.H
hanghaus202313 Nov 2025 14:37This is not possible here. You would need 200 posts for that.
In the site plan, you can see that the neighbor to the south built something similar to what I suggested. What a coincidence.
Be glad that the still quite original house is not protected by any heritage preservation.

I find that interesting personally as well, even though I haven’t looked into it so far. Feel free to share it with us. If I share that, everyone here would be able to find out the exact address behind the property. I don’t want to make that that openly available. You do have privacy rights.
Here is an original plan for one of the houses from 1937
