Granny Flats & Secondary Dwellings

Granny flat and secondary dwelling builder across the Northern Rivers NSW. NSW SEPP exempt-development pathway, complete builds. Licensed.

Granny flats — formally 'secondary dwellings' — are stand-alone or attached residences up to 60 m² that can be built on a single residential block alongside the main home. They're useful for ageing-in-place arrangements, adult children, home offices and rental income.

Most granny flats in NSW are approved under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 as Complying Development, which means a faster certifier pathway rather than a full council DA. Riversedge Building Group builds Class 1a secondary dwellings to that pathway and to council-DA pathways where the site requires it.

What's typically included

Foundation, framing, full fit-out (kitchen, bathroom, laundry, living, bedroom), services connection to the main home or independent meters where required, and council/certifier inspections. Site access for materials and trades is a key planning consideration on small or constrained blocks — we factor it into the build sequence.

Site, setbacks and services

A secondary dwelling has to sit on the lot alongside the main home while meeting setback, private-open-space and site-coverage rules, and connecting to water, sewer and power — either off the main home or with independent meters. On established blocks the practical questions are usually where the dwelling fits, how trades and materials get to it, and how services are run. We assess all of that on site before design so the granny flat works on your block, not just on paper.

Frequently Asked

Questions

How big can a granny flat be?
Under the NSW secondary-dwelling pathway the internal living area is capped at 60 m². Some elements such as patios, decks and carports can sit outside that figure subject to the code and council controls. We confirm the allowances for your site with the certifier before finalising the design.
Can I rent out a granny flat?
A secondary dwelling can generally be rented out. It must remain on the same lot as the main home (a granny flat is not separately subdivided), and any short-stay use has its own rules. We recommend confirming current requirements with your council for your specific situation.
