A couple of energy and wellbeing thoughts:

The open areas are too vast proportional to the overall building size. The ambition of future homes is near-zero or zero lifecycle emissions which is difficult to manage when kWh/person.needs is for the most part 70% of the space.

The volume to external surface area is very low for the floor space which is indicative of poorer energy efficiency.

Both front and back entrances open into the full space with no partitioning. Any climate deviating from neutral temperature is going to have significant effect on the internal climate whenever they're opened.

There's very few if any windows in primary spaces. Natural light plays a significant role in comfort and more importantly, adaptive comfort opportunities.

The master closet will be heated indirectly presumably and its chained through two other rooms. I'd think the external envelope will only

I'm sceptical that having the kitchen exposed to secondary (and exclusively secondary) openings won't eventually result in undesirable pollutants escaping the kitchen extract.. Particularly if an entrance is open and if not, you're one burnt chicken from a full-house deep clean.

Dining table needs to be moved, I think. Putting aside people need to get out their chairs, being squeezed against the wall is claustrophobic.

Purely subjective: The bathroom's far away from the primary activity spaces, bedroom's notwithstanding.

In terms of dimensioning, an admirable effort but probably a bit too zealous. A personal preference though maybe not suitable for where you are would be to have the kitchen dimensions in the internal space rather than over worktops.
