You could install a retractable wall or sliding doors of some sort? OR washable curtain panels mounted from the ceiling to open and close when needed.

Manipalgoyal: I like your basic plan. It is well thought out....What does the top floor look like? The only thing that I would do differently from my very "Western" perspective would be to move the rear right bedroom upstairs and open up the back courtyard to the kitchen area. I would create a "great room / kitchen area with doors that open both to the front courtyard and to the back. This allows for good cross ventilation to help keep the house cool and comfortable on a hot day. It also provides easy access to the rear yard area without having to walk through a bedroom. Now all of the precious outdoor space is easy to use. The other element that I would introduce would be an atrium (or an opening in the floor) all the way up to the second floor with openable windows high up on the second floor to allow hot air to escape to the top of the house and out (since hot air rises) This is called the "chimney effect" and is another way to keep the house well ventilated. Of course this is how it has been done in hot climate countries for years, so you might be familiar with this technique already. Even if you don't change it, your floor plan is very nicely laid out. I would be happy to help you answer any additional questions that you might have. I do have a few questions for you: 1. Where is the laundry room? Is it in the storage space? This does seem a little narrow. How wide is it? You might want to work on how this space actually lays out. Is there a sink in this space too? 2. Why do you have such small openings to the outside from the drawing room and the rear bedrooms? Are they doors or windows? Wouldn't you wnat a door with an openable window with a screen adjacent so that you could have ventilation at night without having the door open? 3. How will you lay out the kitchen? Who is doing the cooking in your household? Is cooking a family event or is it done by a helper? You either want a bigger more open kitchen (Western design) or a more private kitchen (Asian design) Or a combination of both.......To me this is the most important part of the house where the family gathers and hangs out..... I would love to hear back from you. Christine Lampert

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

That explains his opinion. Your description until now was for outlay doors. Slideline 16 is capable for 50-60 kg and 18-24 mm doors only. As I said earlier, not a big fan of bottom running sliding systems. Hope it works fine for you. Steel decorative strip is possible . But avoid deep cuts on the door that would increase the chances of bend/warp.
