Fillomino Skyscrapers (Logical Puzzles Series #2)

There are many Skyscrapers puzzle variations and there are many Fillomino puzzle variations. This is quite a good variation that mixes both the Skyscrapers puzzle and the Fillomino puzzle. It appeared in Oguz Atay Puzzle Contest (OAPC) long back in the year 2009 and this puzzle I created that time to prepare for the OAPC contest and published it around Dec 2009.

Now I am re-publishing this Fillomino Skyscrapers Puzzle as 2nd puzzle in the Logical Puzzles Series. Can you solve this Fillomino Skyscrapers puzzle?

Rules of Fillomino Skyscrapers puzzle

Write a number into each square of the grid. Fields with the same numbers must form horizontally and vertically connected ranges, which consist of as many fields as the number indicates. Two different horizontally or vertically adjacent ranges may not have the same size. The numbers outside the grid indicate how many buildings are visible from that direction.
