Does anyone refurbish Maxis Made Builds and upload to the Gallery?

I may refurb a house in my own game, but I wouldn't upload it to the Gallery. I even took a house from said Gallery and it wasn't complete on the inside. That's okay with me. Finishing work is sometimes just as much fun as building it from scratch. I ended up after playing in said lot, adding onto it. I made it a two-story and wanted to share what I had done. I tried to contact the initial builder, to seek permission to do so, but they never got back to me. So, it's in my game, only.
