Whether you're an investor looking to increase rental income or a homeowner seeking to accommodate multiple generations, duplex developments provide versatile solutions for various needs.

Traditional Duplex Designs

Traditional duplex designs typically feature one home at the front of the property and another at the rear. This layout maximizes space utilization and privacy for both dwellings.

These designs are perfect for longer blocks, offering ample living space and privacy. For example, an 18 x 40 block design can feature a street-front home with a garage at the rear and a yard at the front, providing a longer outlook from the family room and kitchen. Larger blocks, like 18 x 50, allow for even more spacious bedrooms, including a 15 sqm master bedroom.

Side by Side Duplex Designs

Side by side duplex designs are ideal for narrow lots or when you want to maximize street frontage. These designs often utilize shared walls to optimize space and reduce construction costs.

Side by side duplex design

A 19 x 35 side-by-side duplex design can comfortably accommodate 3 bedrooms, 2 bathrooms, a study, and two outdoor living areas. For more compact lots, a 19.5 x 25 design can still offer 3 bedrooms and 2 bathrooms by using parapet walls on the internal boundary to maximize space.

Corner Block Duplex Designs

Corner block duplex designs take advantage of dual street frontage, offering unique opportunities for layout and curb appeal.

These designs often feature 3 bedrooms, 2 bathrooms, and a theatre room. Smart design elements like TV recesses in the family room and computer nooks off the meals area can increase usable space. For higher-end markets, designs can include four bedrooms, a study, and a TV area, with the alfresco, family, and kitchen areas facing the secondary street for increased openness.
