I strongly second One Plan's idea about looking for another architect. If this one is not motivated, all the fame in the world is not going to help. An alternative approach to finding an architect is to find some good contractors who have built things you like. Ask them for architects' names. Make sure they work in your price range. In the meantime, you can find out from your local building department what the set back and height restrictions are. Are you required to build parking areas or garage space, what kind of airspace restrictions do you have for neighbors' views and sunlight, that kind of thing. Often this stuff is on city websites or handouts at the office.

nowdays so many design in upvc window with exhaust fan hole

It seems like pretty decent size bathroom ..u could plan for extra storages too..split dry area and wet area..add glass partitions to separate dry and wet area..u can also plan for wide wash basin area too..

Right but you can give two doors for operating the washroom area. One from the living area and another one from Room. This area is sufficient for the dress room and washroom.
