You could easily bluesreen the windows and use the interior though. (Lando's personal hideaway?) Vasquez Rocks was used for Vulcan in Trek '09 with a lot of CGI tweaking. The movie used a lot more real locations and interesting buildings than most people realize.
Lest we forget, the Lars' moisture farm is a real hotel in Tunisia. ;)
I admit I chuckled when Zordon's HQ turned up on a Star Trek TNG episode though.
