Land class scenery

I am thinking about trying to do some scenery design. Never done anything like this before and have been just reading the threads here. Saw this Land class and was wondering if anyone here has used it and if so how would it compare to FSSC??
One of the things that I really want to do is to add some arrival gates (jetdocks) to my home airport KGSP. I have not found any updates to the airport anywhere that include these. Would this be difficult to do?? Is it just a scenery add on?? Thanks in advance for any advice.
