Wondering about a building south of LV

Hi, I got to visit LV back in 2010, and then was able to come back again this month.  Very nice town!

As we drove up 84 south of town in 2010, I noted a building or structure being constructed, and I saw a couple weeks ago that it is apparently still being built.  It's about 30 miles south of town.

I got a couple good photos of it from the road.  What is this?  I thought at first it was a church or something like that,  but on a closer view I don't think so.  The photos are at the following links.

Any insight would be appreciated.

Cheers, Bill
