Skylights can be kind of a mess. They can leak, sun can shine down when you don’t want it, etc.
Everyone I’ve known who had one had a lot of problems with it.
(Of course, the people I’ve known weren’t in Jordan’s tax bracket, but I doubt a skylight anywhere is without problems.)
I was once enamored of Bucky Fuller type ‘Dome Homes’. Then I met some people who had actually lived in one...:-)
I put a skylight in a mobile home once and it never leaked!
