We have a sloping block (steepish in the middle). We want to run down the block with a large 4m. covered deck at the end (where the outlook is). Our car access would be from the bottom of the block and we'd like a carport/garage with covered access to the house. However if we place the garage under the deck we require 16 stairs up into the house. We don't want to be using lots of stairs every time we come home. Can we put the garage/carport somewhere else? Any suggestions?
