One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

Right now there does not seem to be any symmetry on the path to your door. I would either eliminate the small trees that are there now, and replace them with bushes or shrubs that are equal in height and width, or cut these back and shape them dramatically, so that you have a clear vision to the door. Second, if you could change out the door, eliminating the side window, that's another idea. Sometimes just replacing your front door with one that is bold in color or style is enough to breathe some life into the front of the house. You could also either replace the concrete with pavers or paint the concrete with stain of a color that blends well with with nature.. like a lighter gray or a brown.

Since the lot you describe is smaller than my open living area, I would suggest looking at some of the "shotgun" house plans around New Orleans,LA. I think you can build up and back and get an interesting home with a loft for space. It can be done, A porch with an entry to a narrow hall at the back might work best for you. Will you plan a courtyard (closed)? or what? What part of the country are you in? What are your local codes?

Does this village have any colonial features? The house has too much concrete and nothing to warm it up. Use natural wood hand-made railings...not painted. Balance the railings. Upper railings and lower railings are completely different. They should be taller...a meter high upstairs. Do you have to leave the upper columns by the bedrooms exposed? Bring the brick wall between them forward so the columns are inside the house. Divide the casement windows with 4 panes.
