Switch the front window and your side entrance door, this way your door is visible from the street. Then turn the window in the pantry into a door to gain access more directly to your kitchen, a closet and maybe a bench for gathering items on the way in or out. It looks like you have to go up a small flight of stairs to get to the door, otherwise I'd say put the additional entrance on the cellar wall on the left of your plan. Depending on space you may need to slide this new mud room entrance to the left and you might have room for a longer closet along the pantry wall and a bench opposite the closet along the outside wall. You would lose the cellar but I am not sure if that is another storage area or access to a basement. Just some ideas. Really like the rest of the layout. Hope my little picture helps to explain my ideas.

my suggestions include changes to the roof to eliminate extra valleys and allow the "bump outs" to be under the eaves...Open gables over the porches and alfresco with raked 2400mm ceilings will allow the outdoor spaces to have a much more open feeling without increasing height and the simpler roof should be more economical ..the other suggested change is an increase in the size of the garage to allow for a smoother connection between the two homes as well as extra space for the vanity and wiw... btw bedroom, study, wardrobe and storage sizes are shown separately and the rear alfresco should be added to suit the outlook but a walled courtyard behind the laundry could make a good drying area and handi vege garden and create privacy between the two backyards for your lovely new home,,,btw you should remove identification off your plan

best decision would be to incorporate any changes for the entry with the upstairs renovation .please post photo of the new upstairs and roof and what do you plan for the front yard, fence and driveway?
