You have to apply the normal rules for Skyscrapers:
Each row or column contains skyscrapers of different height (from 1 to 5); the hintnumbers outside the grid in the grey fields indicate how many skyscrapers are visible from that direction.
In addition you have to take the hintnumbers as well as skyscrapers. The numbers in the white corner fields indicate, how many of these skyscrapers are visible from that direction.
Solution code: The diagonals from upper left to lower right and from upper right to lower left.

Oh that's funny, I made almost the same puzzle (with one extra clue) a couple years later: https://maybepuzzles.com/2017/10/28/puzzle-149-skyscrapers-squared/

Hier kam ich mit Logik besser durch als beim ersten. Vielleicht hab ich mich einfach schon ein bisschen eingedacht. Macht jedenfalls Spass!
