Dear Sir/ Madam,
Thanh you for your comments, I did understood that more modify is more time and cost also, to make it reality, you need to call a constructor for: make as built drawing set, clarify which wall need demolish and new construction,… then you get your home as desire and as your chosen design. You could also change two windows bathrooms at staircase to colour back glass, will make your staircase more colorful, beautiful if you have a good plan for renovation.
My principal idea for my concept is nature light for your house, it also a key element of every high-end resort or vacation home,
So as role of designer, I am strongly recommend you do these modification for these good point as bellow:
-Nature light make your bathroom more beautiful, avoid of moisture, you could see that bathrooms could get direct nature light from roof sky light
-Sun light make ground floor hall area more beautiful and luxury, make you feel closer to nature.
-Folding doors at ground floor make full vision to garden and scene beyond.
-Hanged folding door in your master bedroom give you the dynamic space.
-Extend your staircase for more steps, the riser now is 160mm, very convenient and you could remove the solid staircase, and especial is two big bathrooms.
-I would like to keep the elevations as they are, and have a recommend for you as exterior image.
