Pharaonic is an adjective that means impressively large and spacious.

The word pharaoh, witch refers to a powerful ruler who resided in a large temple, specifically in ancient Egypt, came from Egyptian and has since been imported into Hebrew, Greek, Latin and English. Pharaonic is the adjective version of this well-travelled word. It is often used to describe accommodations fit for a pharaoh.

After living for nearly a decade in a tiny studio apartment, my new one bedroom apartment feels pharaonic by comparison. I now even have enough room to put a couch.
