I'm not sure a stacker would be viable in this situation as you have such a skinny block. Excavating to go down will require a lot of retaining/piling to protect neighbours etc

Well done Ash!
I love tiny sites. I have 3 apartments going on 249sqm and 4 houses going on 550sqm.
I can't wait to see your designs if you are happy to share.
