remove the wall. Move your tv to the wall with the room beside the stairs. If you want a partition, add some nice wood elements as accent. Remove the small wall by the stairs, move your washbasin into your toilet.....extend your toilet to underneath the stairs. I assume u using brick n concrete for the build. Now you got more living space n toilet space.

You are considering installing a rooftop pool, right? I don't have one, but I did pull up this link for you -- it has some good information: http://outerspacesinc.wordpress.com/2010/01/07/on-roof-top-swimming-pool-construction/

ssuresh316...I hope all the pros on Houzz are in agreement here. Your room can be built as you envision it but we pros leave those sort of questions to a different kind of pro. Joanne is correct in that you need an engineer...but call a structural engineer. Civil engineers do roads, drainage, utilities and surveying. Structural engineers tell us how to make the building stand up.

Yup, in this case it is possible. But: - - having a proper walk in closet is hard - guest toilet will have to serve as common for living area. - average bedroom size would be around 12'X12'. - If there is staircase it will also take around 60-70 sqft area at least. - Please Note- Around 20-25% of total built up area is just wall area. So like if your house built up area is 1000sqft then the Carpet Area( the area which you will be able to see and use) is around 800sqft. Also, it depends on your lifestyle also, the way you live as it is a very subjective thing. For some people 12'x12' bedroom size is more than enough while some prefer having a 20'X16' bedroom with 10'x8' walk-in closet. It would be better if you could provide layout of the land and other information, there are many other factors that need to be consider for any house design. :)
