Dutch Flat Mates: N-Sumscrapers
(Published today, 07:00 by Flinty)
This has been a weekly series since '18 Oct 23'. Here is a spreadsheet link for all the previous puzzles in the series, which also has a few teasers for upcoming constraints/guest setters in the series (subject to change).
This alternative link offers a limited LMD search for Dutch Flat Mates.
Special Thanks
This week's inspiration is last week's DFM guest setter Richard, with yet another lovely entry in his Sudoku Variants Series: Episode 475! I promise it's not as daunting a constraint as it may first sound, and it's very cool!

Initial Setter Difficulty: 3 / 5
Hint to start
The 5 clue is fully forced on its own (don't make 5 sad!). In some clues the total outside is far easier to deduce than the sum itself. The digit 9 has a wonderful property if it is included in the sum!
Visual Example:-
From the left, the visible buildings are 4, 7, 9
- Therefore N here is 3
- The first 3 digits are 4, 3, 7
- The valid clue would be 14 (4 + 3 + 7 = 14)
-
From the right, the visible buildings are 8, 9
- Therefore N here is 2
- The first 2 digits are 8, 1
- The valid clue would be 9 ( 8 + 1 = 9 )
Solution code: Row 4 digits
