Puzzle#63: Skyscraper/Outside Hybrid Sudoku

Place a digit from 1 to 9 into each of the empty cells so that each digit appears exactly once in each row, column and 3x3 outlined box.

ADDITIONALLY
Clues at the left and bottom are Outside clues, and clues at right and top are Skyscraper clues.

Outside rules: The digits outside the grid must appear in one of the cells in the first box (till the next bold line) seen from that edge of the grid.

Skyscraper rules: Consider each number to be the height of a building. The numbers outside the grid indicate how many buildings can be seen when looking in that direction (taller buildings conceal smaller buildings behind them).
