Architectural Elevation for Lift and Stair case -- 2

I am looking for a Architectural Designer who can give me a Elevation designs and options for my the staircase and Lift area that I am adding to my existing house to access the second floor. Right now it is a Ground floor + 1st floor building. I am adding another 2 floors and am building a staircase with lift to access that. I would like to see what elevations can be given for this area. I have added the drawings in the attachments. I have added some interior pictures on how i want the interior to look while the exterior needs to be designed.

I have also added the CAD drawings for reference.
