Rotating my Upgraded Thatched?

I upgraded my Thatched Farmhouse which was, in its original version, facing West. I wanted the upgrade to also face West. When I upgraded, the upgrading image was so big I didn't notice which way was the front and I completely missed that it was actually facing North. I also was expecting to see a capability to rotate it, which I had heard about. But I didn't see it and didn't know at which point it would be presented, so I built it and -- oops -- it's now a Harvester's Farmhouse and it's facing North and I can't find any way to rotate it now, after the fact.

I never did see an option or interface for rotating the house (I'm sure I missed it), so I didn't know what to expect nor do I know what to expect now, but I would like to rotate it to face West. Is there any way to do that other than putting in all the gazillion mats all over again??

Thanks,
