Adds a large residence to Breezehome in the basement with a separate outside entrance. Using a copy of the Great Hall from Solsteim.  I've added Smithing, Alchemy, Enchanting, and Wood Chopping, to make this a full, workable residence for the Dragonborn. You can enter the addition from inside or just outside Breezehome. The inside trap door is just under the stairs. The outside trap door is to the left of Breezehome as you are facing the house. Inside the addition, the doors operate as the entrance and exits to inside Breezehome itself, or outside to Whiterun. I have not changed the storage containers, so at present they respawn. This is good for collecting items, bad for storing your own items. For the present, please store your items in Breezehome itself. I might change this later, if I see requests for it. It is possible to access the basement, even if you don't own Breezehome.
The addition has a female marriageable follower who is highly skilled in destruction. I've used her as a follower quite a bit and really like her. She is a Redguard named Addama.
I hope you enjoy the mod. I made it for myself since I always liked the Great Hall, and like so many others, wanted something more from Breezehome.
