What do you need the door between the foyer and the terrace for? It won't be cheap and will probably be used rarely. I would omit it and plan a wider fixed glazing if the view of the garden is nice.
I find a 3M peninsula very bulky there, especially with the door to the cellar (I assume). I would already go to the kitchen planner if you haven't done so yet. I think another solution for the kitchen might be better.
