I need a floor plan designer

I am building a house and would like some input on the floor design. It is a two-story, four bed of around 200 meters squared internally. I have drawings from the plans that have been submitted for planning approval; however the internal layout was not finalised; rather a general one put in. I have played around with the layout and have some ideas but it would be great to get some other feedback and suggestions. I will attach current files.
