This puzzle has a different start than normal for this type. So here is a starting hint in a tiny font. Copy this hint, paste it in a text editor and enlarge the font size if you want to read it:
Consider columns 3,4,5.
There have to be placed a lot of building segments in these columns.
Column 4 is almost full with 8 segments, leaving only two cells empty.
Try to fit two buildings with a 'length' of 4 in this column, and you will see that you don't get enough cells covered in columns 3 and 5.
So there are three buildings in this column, covering 1,3 and 4 cell, 2,2 and 4 cells s or covering 3,3 and 2 cells. Now it needs only limited eliminations to get started....
Solution code: The number of knicks in the loop; row by row, top to bottom. (Example: 40228244)

Puh, dieses Rätsel hat sich lange gewehrt.
Erst als ich beim Rätselwochenende Christian erklärt habe, warum es nicht geht, konnte ich es lösen... ;-)
