Plane Addict,
Re viewing areas, unfortunately like nearly all of UKs airports,albeit Manchester, there is little appetite at BHX or provide anything decent.
The reason is that there has to be a business case for it.The views from the aviation hobby area on the top floor used to be great but all the building work ruined most views. It was then hardly used apart from school holidays so got chopped.
The 2nd photo you provide can't happen anyway. The new airport service road has already been ploughed just behind the Tristar Hotel.When finished it all goes airside.

We will have to wait and see what the views are like from close to the runway extension. However likely to be more distant views of the actual terminal and aprons Im afraid.
