Blocked View Skyscrapers Puzzle New Logic Variant

I created the blocked View Skyscrapers puzzle type for the "Contest for best logic innovation". This puzzle is a variation of the famous skyscraper puzzle.

Rules of Blocked View Skyscrapers Puzzle


Fill the grid with digits 1 to 4, so that each digit appears exactly once in every row/column. The cells in the grid can be considered individual buildings, and the number inside the building is the number of floors. A number outside the grid indicates how many buildings can be "seen" from the corresponding direction. Additionally, each row/column contains a blocker. An observer cannot see beyond the blocker. 
A building is seen by an observer if there are no taller buildings (with a greater number) between it and the observer, and it is not blocked by a blocker in that direction.
