Websites to design home?

I am not planning on buying a home, just inspired to think about how I would build mine. I am horrible as anything art or measuring related, so I was wondering if there were and websites that you could go on and design every aspect of your future home. I always see these one those home-builder/renevator shows on television, and im inspired to do this too lol 😛 Thanks in advance.. 🙂
