ᐅ Passive house floor plan feedback: ground floor and upper floor, open kitchen, cloakroom, and family rooms discussion

Hello everyone,

Today, I would like to open the discussion about our floor plan and ask for your comments and suggestions for improvement ... THANK YOU ;-)

Here are a few basic explanations:

• The house is intended to be as energy-efficient as possible (towards passive house standard). Therefore, it is rectangular with a 45° pitched roof ... no projections, bay windows, dormers, etc.
• At the top is north and the street
• Top right is the garage, next to it on the left a wall/privacy screen, and further left the driveway
• The background image still shows the old, demolished house ... don’t be confused ;-)

# Ground Floor:

• You drive forward onto the property ... then into the garage. When leaving, you reverse out of the garage, turn left in reverse, and then can drive forward back onto the street.
• In front of the garage, you enter directly through a door into the utility/technical room (the only room without natural light)
• From there into the cloakroom
• From the front door, you take 1 or 2 steps past the guest toilet also into the spacious cloakroom
=> I had initially planned to place the cloakroom on the exterior wall, but then the guest toilet would have no natural light, which my wife did not want.
• Opposite the guest toilet is the staircase going up; under the stairs is an office/guest room
• Straight ahead leads to the open kitchen/dining/living area
• The terrace on the right has shade in midsummer ... there is a door from the kitchen directly out there
• Another door to the "south terrace" is at the bottom center

# Upper Floor:

• Basically self-explanatory ... children’s rooms with children’s bathroom, master bathroom, walk-in closet, master bedroom

Where do you see potential for optimization?

Thank you in advance for your ideas!
