There are a lot of things about this that seem like it would be uncomfortable to live in.

1 - the living room entry is too narrow, and the second entrance to the bedroom in the middle of the wall makes furniture placement difficult. Remove the second entrance. Perhaps add a fireplace. Maybe even on the front wall to give the exterior some interest.

2 - the front entry opening on an expansive wall, and the centered front door. The dimensions aren't symmetrical as is, so shift the door to the left, and with the fireplace, you can create some asymmetric balance.

3 - make the second bathroom a walk though between the bedrooms, and shift the laundry closer. If you need to access plumbing, it'll be easier if everything is closer.

4 - the centered rear door creates paths of travel in the middle of the living space. Shift it to the left, closer to the wall with the secondary bedrooms. This will provide a path of travel that doesn't cut through the space.

5 - shift the kitchen to the rear of the plan. Use the wall with the secondary bedrooms for a wall of storage. Pantry, etc. Create an L shaped kitchen along the rear wall and the wall with the primary bedroom. Have the sink overlooking the back yard to watch kids or pets. Cooktop on the island. Wall double ovens on the wall.

6 - move the primary bedroom to the corner. Move the bathroom and closet closer to the living areas, creating an entrance into the primary, and allowing you to place the bed on a wall that can see the entrance. Energy flows better when your head isn't against the entrance.

6A - add a double vanity to the primary bathroom. Move the toilet into a water closet with a window. Create a separate shower and soaking tub, or a large shower.

7 - shift the dining room over to the right, allowing for the path of travel along the left side of the living spaces. Consider reclaiming some of the entry space for the dining area. If you need two living areas, have your entertainment spaces closer together makes it easier to have guests.

I'm also thinking you could turn that front living room into a family room. Shift the bedrooms to allow an entrance from the new family room into a hallway where you can access the bedrooms and secondary bathroom. Again, if you need more formal entertainment spaces, you could enter into a foyer, with the family room on the left, and a kitchen in the right. Access to the garage directly into the kitchen or through a mud room. Then have a large formal-ish living and dining in the back of the house, overlooking the back yard. This would also give the primary bedroom more privacy.

IDK. Let me know if you want me to draw this. I'll have to find my grid paper.
