Is Sheldon hilly or flat?
Sheldon is gently undulating: the median lot slope is about 7%, and 8% of properties sit on slopes of 15% or steeper. Ground level runs from roughly 20 m to 77 m AHD across the suburb. Slope drives site costs - cut and fill, retaining walls and driveway grades - so it is worth knowing before you commit to a sloping block.
