Our Story

18th Street started about 40 years ago, with a 2-year-old girl colouring the small boxes on printed A1 masterplans. 

At the time, she didn’t know that they were allotments, or that this big sheet of paper represented hundreds of allotments in Hallett Cove’s new Karrara estate, but she knew that she loved it and wanted to keep colouring. 

For the next 5 years, she would watch the people come and go from the front office of her family home (the only house in Hallett Cove at the time). As each visitor left, her father would shake their hands on the doorstep. He had sold them their dream… a new block of land.

Real estate, and in particular, residential projects, courses through Carly's veins, and is at the core of 18th Street’s business. We live, eat and breathe the idea of that handshake between the sales agent and the buyer. 

It’s the promise of a new future.
