Only heights from 1 to 4 (or 1 to 5 for the second puzzle) must be used, the remaining cells contain hedgehogs (one hedgehog per row/column). A hedgehog does not block the sight to any building behind it. It is only visible if it is located in first position; in that case, it counts as two visible buildings.
Solution code: For each of the marked rows (from top to bottom), the complete contents (from left to right) must be entered. Enter a minus sign (-) for a hedgehog in the solution code.

Ups, da ich übers Wochenende verreist bin hatte ich mir den Wettbewerb nicht angeschaut und deshalb gar nicht bemerkt, dass es Training ist. ;-)

Bei meiner Lösung kann man im oberen Rätsel in der 3. Zeile 3 Häuser sehen (anstatt 2).
