Seems silly to have 2 bathrooms on first floor but none in the master suite (as it originally was) on the top floor. Is there a problem getting plumbing up there?
It wouldn’t work for me as previous posters have pointed out, the living area downstairs is open plan. If you want dc sleeping on the same floor as you then you have to use both beds on the first floor- unless you squeeze in the top two rooms with no wc. Assuming beds are on first floor then your second reception area has to be the top floor.
But it’s very nicely done and only you know how the space would work for your family.
