Given the very large living area, the USP of this apartment, there are a variety of screens available which can be used creatively, mobile or fixed, see through, translucent or opaque, full height or part, etc to divide the spaces and yet give a free flowing look of a large open space, the light and views from the large windows.

Well. You may not be able to install a traditional home theater that includes a projector set up to project on a screen as it needs the room to be blacked out when you watch the movie. However, a LED TV with AV receiver and speaker setup should be still possible based on the size of your room. It's your preference. I would advise go for a dedicated HT room if you are investing more on the projector, receiver and speakers. If your investment is less then a living room set up is still okay.

The most concerning issue when arranging an inside is the situation of the washbasin in the feasting lobby. Washbasin shouldn't be exceptionally close or a long way from the feasting corridor. The washbasin must be at adequate good ways from the feasting corridor. These days, there are washbasins accessible in various reaches. So you can pick the shading, size and configuration as per the course and area of the feasting corridor. Select a round shape washbasin the North and West way, and square or rectangular in the South and East zone. Since reflect is hung over the washbasin and water shapes a basic piece of the wash basin, it is smarter to put it the North or East way of the feasting corridor. Try not to put the washbasin the South or West way of the feasting corridor. On the off chance that there is a washbasin in your home in these bearings, at that point promptly eliminate the mirrors joined to it to diminish the vastu deserts. It isn't a great idea to have washbasin under the flight of stairs territory.
