The garage is now gone or just not shown, and the property the same as in ?

I say nothing without the floor plan! Because something doesn't fit (living room as a passage with a massive area, while no storage is available). To assess this, the floor plan must be available. No one benefits from a living room door opposite the staircase - it would be different to open the dining area.

I think it's quite okay. I would convert the kitchen door into a sliding door. If the floor plan from 11ant's link is correct, I find the garage really annoying. I don't think I would "attach" it to the house, but rather leave it lonely at the street in front. Then a living room window in the west would also be possible.

How about the utility room door under the stairs? Have you already calculated the heights exactly so that it fits? How wide is the door?

The views probably still need to be refined.

Style, roof shape, building type: townhouse, because of storage options in the attic and maximum use of living space given the floor area

This is a common misconception. Geometrically, you maximize the area with the same perimeter if you make the shape square. Practically, you only create unused space inside the house – see the living room entrance and hallway above. You certainly do not gain usable space this way. I’m thinking radically open and remove all walls to the kitchen and living room, leaving only the cloakroom. Place the dining table centrally and regroup the kitchen... now it becomes a very special living space where the table becomes the center of life. Not everyone’s taste – for a family that does a lot together, an option.

Practically you only create unused space inside the house - see living room entrance and hallway upstairs.

If I don't want the stairs in the living room, I don't find the hallway too big, neither downstairs nor upstairs. What about you?
Sure, the openness of the area is nice, but with 2 kids who want to sleep while mommy and daddy are still watching TV, it's always a problem.
