Cycler24 posted a topic in Q&AI just started using this product. I am trying to find information on how to construct a deck on top of an existing deck? I currently have a doulble deck system and need to show modifications to my current deck system, water-proofing upper deck in order to build lower deck as an out door room with enclosed ceiling, lighting, etc. I need to show the plans for permitting and need to draw both the upper and lower decks. I completed several searches and could not find the information. I have the Home Designer Suite 2017. Thanks for the assistance.
