Almost as good as a "specious family home"

Back in 2007, I posted about a real estate listing that offered a "specious family home," and that wasn't unique: a search for that phrase brought up an amazing number of "specious homes" for sale [my 2017 note].

Yesterday we saw a listing almost as good.  This one had an "expensive foyer."

Like this, maybe?  But I think they meant "expansive."
