Would definitely pay attention to what rooms will and will not get sunlight ... that can matter a lot over time as sunlight can affect mood -- the rooms and the people in them. It can also make a difference in room temperature.

I'd move the back wall of the great room (living/dining/kitchen) back to be even with the rest of the back wall of the house. That way you'd be walking between the kitchen and dining areas from the foyer to get to the living room against the back wall . Then you could add a full width back porch as deep as you want/need your outdoor living room to be and, importantly, you can add skylights in the porch roof so the living room could get sunlight.

If your lot is nearly level, you could move easily between that back porch and any patio and/or pool and/or tennis court and/or garden and/or pergola and/or gazebo and/or any office/shop/studio building you might have out back.

On the front of the house, instead of just a small portico, I'd extend the portico into a porch the full width of the courtyard ... again skylights to enable sunlight to get to the kitchen and dining area. You could even make that front porch an "L" shaped porch to extend it alongside the right wing of the house to connect the unconnected bedroom with the house with a sheltered roof.
