I'm going to guess that it's a custom door. You need to find a place like these:

I have a neighbor who works for an ad agency that had a contract with a security door manufacturer. He came to me one day and asked if they could put a security door on my front door (it was a really pretty door sort of like the one you like, leaded glass, lots of interesting detail) so they could photograph it for an ad. They gave me a free security door as payment.

Likely, someone from an ad agency asked this homeowner if they could put the lights on their house in return for some kind of compensation to use it in the Costo ad.
