Does the slope of my block affect the development potential?
Yes. The slope of a block can affect its development potential because it influences building height, finished ground levels, excavation, retaining walls, access, drainage and how the development responds to neighbouring properties. A sloping block is not necessarily unsuitable for development, but the design may need to respond more carefully to the existing terrain.
A sloping block can still be developed, but the slope may affect where and how the building can sit on the land.
For example, a steep slope may require more excavation or retaining walls, and parts of the building may sit higher above the existing ground. This can affect building height, driveway access and the relationship of the development to neighbouring properties.
We would normally review the site levels and survey information early in the design process so the development can work with the slope rather than relying on significant changes to the land.
