We need a to scale detailed floor plan showing every window doorway where the doorways lead and all measurements clearly marked . The floors look nice so maybe explain what they are and why you want to change them. I usually start a big renovation with the kitchen since that is for me the most important space in the house.I usually suggest you live in a space for a bit before doing major changes. Homes have a way of telling you how they function and when you try to fight that it never ends well. So I suggest you get an Interior Designer and hopefully one with Kitchen Design experinece too. The wall that was partially demolished needs to be shown in your plans and for me that start would be sort of separation bewtween the entry door and the rest of the living space but please get some pro help.
