I heard of an architectural firm that the design department was known as the Room Design Apes.

None of them will make knowledgeable selections to auto populate anything with,even if you can figure out how to get started with a floor plan. That is the dfference between intentional human design and rote copying of things not that original or inspiring to begin with.

I havent' used it but look at floorplanner. Not sure it fills all your needs but worth checking out and it's free.

I am sure whatever you find will be worth every penny.

@mark I don't really understand what you meant but is there any youd recommend? Even if it's pricey just needs to be user friendly
