A lot of blocks around Wollongong, Thirroul and Bulli aren't flat, and it's one of the trickier things to get right in a design. After 30-plus years working across the area, we've come across just about every kind of difficult block there is, and we design around the slope rather than fighting it.

Retaining walls, steps, drainage, we build all of it into the design from the start instead of bolting it on later.
