Our Granny FLAT DESIGNS

 Granny flats—also known as secondary dwellings—have become an essential part of Australia’s evolving residential landscape. Whether intended for extended family, rental income, a private studio, or guest accommodation, these compact homes can offer remarkable value and flexibility. When thoughtfully designed, a granny flat can enhance both the functionality and long-term potential of your property.

At Gir.Arch, we’ve spent the past four years crafting tailored granny flat designs—successfully delivering over 200 projects across every Australian state and territory. These range from simple detached studios and attached extensions to two-storey dwellings, garage conversions, and custom solutions for narrow or irregular blocks. No two sites—or councils—are alike, and we approach each project with care, precision, and a clear understanding of planning context.

Our team is well-versed in navigating diverse state regulations and local overlays, including bushfire-prone areas, flood zones, easements, and blocks with challenging slopes. As experienced granny flat builders and design consultants, we prepare all necessary documentation for both DA (Development Application) and CDC (Complying Development Certificate) pathways—ensuring approval requirements are met from the start.

We also routinely address complex physical and technical site constraints, such as sewer lines within the build area, steep terrain, limited access, and strict setback controls. Through a collaborative and transparent design process, we help clients make informed choices around layout, materials, and spatial strategies—balancing functionality, buildability, and design integrity.

This page showcases real examples of our work, reflecting a broad spectrum of granny flat designs—from compact backyard dwellings to elevated solutions for difficult terrain. Whether you're looking to expand your property for multigenerational living or seeking an income-generating addition, we believe there’s almost always a smart way to build a granny flat.

The key lies in understanding both the opportunities and the limits—and working with a team that turns site constraints into well-resolved, buildable design solutions.
