Hi there, I did a Torrens Title hammerhead subdivision in 2010 and sold the subdivided land behind my home. The person who purchased the land and built a dwelling on it never installed a concrete driveway and instead just filled it with gravel. The entire southern side of my house is the boundary to the driveway and in recent months I have noticed water damage to the external wall and a lot of cracking and have major cracking occurring inside my home also. I am concerned about the fact a proper concrete driveway with a fall to the street was never installed as there is clearly no drainage or ability for water to go anywhere but into the ground against my foundations. I have begun to question if this is in fact legal given my home is on the boundary and my foundations are being exposed to water because of this. I was very young when I did this subdivision and it was a very stressful time for me so I didn’t probably ask the right questions back then. I have uploaded an image of the driveway and I would greatly appreciate anyone’s advice or information as to whether this gravel driveway is legal or not. I’m located in the western suburbs of Adelaide. Thank you.
