Need help fitting in an internal staircase into this design

Hi all,

I have finalized the following design for my one floor independent house....I have followed vastu principles where I can and want, especially entrance in NE corner, kitchen in SE corner, puja in NE/E, bedroom in SW, bathroom in W etc. I am planning for a water tank in the SW corner on the terrace. My question is : the staircase is obviously wrongly placed as per vastu and needs to be in SW/W areas. However, I am unable to place it in a way where it is accessible from the hall and at the same time I retain the bedroom where it is - open to the E and S sides for morning sunlight and aeration (my plot will have trees in all of East and South).

Can forum members please help me with this?

I know there may be errors in my vastu compliance. Please point out any vastu issues only if it is major, as hearing anything negative about my almost final design, as you can understand, can upset my sentiments about the design.

Thanks
