Duplex Builders

As Sydney continues to grow, something’s got to give.

With available land tighter than ever, homeowners are looking to get more from their blocks, with a significant number replacing older single homes with two new ones on the same site.

Known as duplexes, these typically sit side by side or one in front of the other, and have a common wall.

Archicentre general manager Cameron Frazer says “There’s an obvious value proposition around developing a piece of land, given continually increasing land values. It doubles the density on the land but potentially it can more than double its value by putting a second dwelling on it.”

What is a Duplex?

Duplex’s, also known as dual occupancy allows you to live in one and rent the other or rent both as an investment.

A duplex consists of two attached dwellings on a single allotment of land.  You can then subdivide them into two saleable properties as either Torrens or Strata Title.
