Sims 3 lot conversions - floor plan help!

When I was playing sims 3, I really enjoyed playing in Dragon Valley. I was wondering whether anyone has recreated any of those houses/lots for sims 4 as they would be excellent for a medieval challenge that I’m hoping to eventually do? Also, whether there are recreations of houses/lots from any other the other sims 3 worlds or if anyone knows where I can find the floor plans to them so I can redo them myself? Thanks!
