Hi, everyone:

It's hard to tell from these shots but the structure is already mind-bending even though it is still many months away from completion.

I wonder if "mind-bending" here means "strange".

More context:

I find it has two meanings from my dictionary:

[usually before noun] informal
1 mind-bending drugs have a strong effect on your mind and make you have very strange feelings and experiences
2 difficult to understand:
Infinity in space is a mind-bending concept.

I'm not sure which meaning can be applied in this case.

Best wishes
Hi Hly2004

What the author is saying is that the building is so unusual that it's difficult to believe your eyes. In this context, I'd say that 'amazing' might be a better one-word definition than 'strange'.
I've got it, Thank you, Yankee
