Rear deck extension & front entrance 'deck'

I am looking to get my rear deck extended by essentially doubling what it is now - approx 2m x 5m. I have attached the existing deck in the images. The second job I would like done is to create a timber floor front entrance to the property. It is currently tiled. I am hoping a deck could just be built overtop of this but unsure if possible - would need advice on that. I have attached images of the exisiting entrance way as well as an image of what Im hoping it will end up looking like.
