Hi guys This is my first post, so any mistakes please be gentle . I own a 840 sqm property in Sydney West coming under Holroyd Council. I had a chat with Council about going forward in building a duplex and the Town planner said that there will be no issues in building a duplex and selling them separately. But, she said two main things 1. The house slopes towards the property, so I need to work on Easement with my neighbours on back or work out a solution 2. One half of my property is in flood zone so the Architect needed to work together with Council to put together the solution for flood evacuation plan etc.. Do you guys see the options for me, like raising the land, but I am not sure whether that would shoot up the development cost.. Any pointers, please ..
