Two new windows

We would like to add 2 windows to our house. These will be aluminium frame with a timber surround. The first window will be at the end of a hallway and we would like it to be around 2000m high by 500mm wide, double glazed and not able to be opened (fixed?). The second window is at the top of internal stairs and we would this to be approximately 700mm x 700mm, double glazed and able to be opened. I have added drawings of the measurements of the space and windows and also photos of other windows in our house already. This work is not urgent. Required window size is flexible.
