Good start. Looks like a simple U shaped plan. one thing that would bother me is a commode that shares a wall with a bedroom wall and this happens twice in this plan.

a bathroom layout like this could avoid that

Divorced from the reality of scale in thought and in scribble.

No worries, its not mean. Thanks for the feedback. You are correct that the lanai looks huge in proportion. Obviously it isn't scaled but I was trying to have the lanai go across that entire side but with the dining area and master pushed out then it makes the entire area pretty big. We started with a plan that was straight across but decided to push out master to take better advantage of the view and we had thought to separate lanai somehow between main area and master to make it more private. That area needs more work, I agree.

I was trying to avoid that bathroom situation actually. The guest bathroom and kids bathrooms are both tucked down a short hallway although perhaps their entry doors are still too visible as drawn. I'll look at that as we do better drawings.

The master is one of the reasons I posted. It does not enter through the bathroom at all so another failure on my sad sketch. I have had difficulty envisioning a good layout for the master plus closet and bath. We did not want an entrance door to the room straight off the living room. But we also want to have the bed on the interior wall facing out to the views so its difficult to place the closet and bath entry. I wanted the closet and bathroom closet together but I also dislike the idea of entering the closet through the bathroom. So I came up with one plan to have hallway going straight towards the master bedroom but just before entering you can turn right to a short hall leading to walk in closet on the right and you pass by that to the bathroom entrance. My husband thought some more buffer between living room and bedroom would be nice so this plan has the same hallway to the right before you enter the master leading to 'hers walk in closet" and the bathroom but also has a regular "his closet" with sliding doors along the left side of hallway as you approach the master bedroom. The hallway as you enter to the master bedroom area could also be completely closed off by a door so that entire area can stay private.

Does that seem more reasonable?

I understand what you are saying about the master but I think you'd have a very hard time getting furniture in and out of that room as planned.

It's not as effective as a bubble diagram. You're trying for spatial relationships without considering the sizes. That's outside a bubble, which considered adjacency. You're hampering yourself instead of helping yourself when you start to draw boxes without sizes.

The devil is in the details. Post a scale plan and exterior elevations and you will receive better feedback.

Does the topography etc. allow for the driveway to be on the south side of the lot? That way it wouldn't be in the best part of your view, and it would be shorter (less expensive.)
