Floor plan living room-kitchen

Having a room program is definitely useful. You get clear on which room you want where. Do you want the kitchen, dining, and living areas together, or the kitchen and dining together with the living separate, or each room separate, or dining and living together with the kitchen separate? In what arrangement should these rooms be located relative to each other (we want the kitchen separate and dining and living together, but the kitchen should still be more in the southeast, dining to the south, and we don't care much about the location of the living area as long as the sun doesn't disturb us while watching TV—I don't need natural light there, the kitchen should be close to the dining area). Should the study also serve as a guest room, does it need natural light? How many bathrooms do you want and on which floors? What kind of staircase should there be? What are the no-gos? Minimum sizes are also not a bad idea. You write all this down and then go to a planner/architect or someone else. If you show up with concrete measurements, you are putting blinders on the planner. They can plan more freely and bring in their own ideas better if they don't have a "finished" plan from you in the back of their mind ;)
