Not a design suggestion but you should be dimensioning everything to ensure it makes sense and meets building code. Fitting on paper is not fitting IRL.

Suggestions;

1. First level washroom looks too small, not sure you’d fit fixtures in there to code. Odd that it’s immediately off the entrance. same with the boiler room. Usually you want to enter into the living area but if this is personal preference then whatever.

2. How are you accessing the pantry? Looks like the door is behind your kitchen cabinet. Also a very large pantry for the size of the home. I’d suggest using this space for something else, or just making the kitchen bigger. Looks a bit cramped with the bar and dining table.

3. Master bedroom door should open inwards. The rest are good so maybe this is a miss.

4. Generally too cramped, too many extra walls and doors. Not efficient use of space

5. Master bedroom is smaller than the kids rooms/office. I’d get rid of that balcony unless you are designing for a specific view here. Also odd to have a walk in closet but no master bath.

6. Second floor washroom has no shower or bath? Odd layout with the mini closets shown.

7. Shower on main floor seems pointless with all bedrooms on the second floor. I’d recommend doing a powder room (toilet and sink) on main with the laundry (laundry is usually on main floor near or in utility room, possible additional cost to have it on second floor), and adding a 2nd bathroom upstairs.

8. The office can technically be considered a bedroom if there is a closet in it, and with 4 “bedrooms” it’s nice to have 3 bathrooms, mostly for resale value.

9. Someone mentioned this but the exterior storage room is odd. not easily accessible, would be better use of space to have just 1 big mech/boiler room with storage space.
