I think it’s possible to turn some conditionals into participial phrases & vice versa. Let’s look at a few possible examples.
My example:
Conditional: If you catch the express, you will get here early.
Participial Phrase: Having caught the express, you got here early.
Yahoo site example:
Conditional: If she sees such a terrible scene, she will faint.
Participial Phrase: Seeing such a terrible scene, she fainted.
Your example:
Conditional: If you turn to the right, you will find the building.
Participial Phrase: Having turned to the right, you found the building.
