ᐅ Floor plan for a 200 m² gable roof house on a 780 m² plot

Hello! We are currently on the third iteration of the plans for our house together with an architect. The two images below are based 90% on the architect’s proposals for the ground floor, while I have currently designed the upper floor myself. The orientation on the plot is fixed, meaning we get evening sun from the left side of the plan. At the moment, our terrace faces south, which is unbearable during summer, so we have moved the seating area to the northeast. That doesn’t bother us since we plan to have outdoor heaters anyway. The garage must remain on the left side of the plan because all utility connections are located there. The house will have an asymmetrical gable roof with a 35° pitch facing the street (southwest, for photovoltaic panels) and 25° facing the garden. The ridge runs parallel to the street. As a result, the garden side has almost no knee wall, while the street side is about 1.80 m (6 feet) high.

Here are the parameters first:

House Design
Who designed the plans? Architect + own modifications
What do you like most? Why? Entry area, access through the garage (dog cleaning area), lots of glass in the living room, covered seating area outside
What do you dislike? Why? Upper floor, rooms possibly too small, guest WC on ground floor actually too big due to recessed front door
Estimated cost according to architect/planner: 700,000 € without land (land already owned)
Personal price limit for house including fittings: 700,000 €
Preferred heating technology: heat pump + photovoltaic

If you have to give up on which details / expansions
-can give up: living room size, bedroom size, possibly a child’s room (we only want one child anyway, but life happens…)
-can’t give up: pantry

What is the most important / fundamental question about the floor plan in 130 characters?
Is this a coherent and well-functioning plan?
