You know, if I knew how to mod then I would probably rebuild that house into a fitting player home for the Thane of Whiterun. Perhaps the player could rebuilt it in the same way the player built the Lakeview Manor not far from Falkreth.
Sure, Breezehome in Whiterun may sound nice, but when I bought it with all the furniture the first time I was disappointed by Bethesda's design of how Breezehome looked like inside.
I consider Breezehome to be the worse player home in Skyrim and one reason I think most people would agree to is that the player need to choose between an alchemy room or a bedroom for the adopted children if you have Heartfire installed.
If that weren't enough the entire interior in Breezehome between vanilla Skyrim and Heartfire was completely changed. Heartfire had the best interior design for Breezehome IMO.
