How to enable rotation of buildings?

Building as in those that are being constructed in melee maps right? Set "Stats - Is a Building" to False at Object Editor and as far as I know, you can rotate it but still keeping it as a unit.

You can make the building into unit and rotate it like Hell Master wrote, then you simply change it back to building.
The downside is that any movement with the building will rotate it back to its original angle
