"Granny flat" isn't a formal planning term - councils typically refer to these as secondary dwellings, and the rules governing size, setbacks, parking and who can occupy them vary by council area and zoning. Most Queensland councils allow a secondary dwelling on a residential lot subject to size limits and site coverage rules, and some restrict occupancy to family members or place conditions on renting the dwelling out separately. Because requirements differ from council to council and can change, it's worth checking with your local council early - Saltair manages design and approvals in-house, so we can help assess what's achievable on your specific site before you commit to a design.

• Rental income: A self-contained granny flat is one of the more straightforward ways to add a second income stream to an existing property, particularly on a block close to transport, schools or employment hubs.
• Ageing parents or multi-generational living: A small, private home on the same block lets ageing parents stay close to family while keeping their own space and independence.
• Home office or studio: A separate small dwelling gives a business owner or remote worker a proper work-from-home setup without eating into the main house.
• Extra space for a growing household: A compact one-bedroom home is often the simplest way to help adult children or extended family gain independence while remaining nearby.

A granny flat is almost always built on a site that's already occupied - your existing home. That changes what matters most in the build: minimising disruption to the property you're already living on, keeping the footprint of the build itself small, and getting the second dwelling finished with as little site disturbance as possible.

A traditional site-built granny flat still means months of tradespeople, deliveries and site works happening around your everyday life. A modular granny flat is built to completion in Saltair's Queensland factories, then delivered and installed on your block in a fraction of the time a site-built equivalent would take - shrinking the disruption to a matter of days rather than months, with the same NCC-compliant construction standard as a full-sized home.

Every design below is a 1-bedroom, 1-bathroom modular home, built to the same quality and compliance standard as Saltair's larger family homes:

• Cardrona 111: Saltair's smallest design at 31.0 sqm of total living space (29.6 sqm living plus a 1.4 sqm deck) - a streamlined studio suited to guest accommodation, holiday stays or the most compact granny flat brief.
• Hunter 111: 40.0 sqm of total living space (38.6 sqm living plus a 1.4 sqm deck) - one of Saltair's most compact designs, built for guest accommodation or short-stay living.
• Keppel 111, K'gari 111 and The Range 111: all 52.8 sqm of total living space (48.2 sqm living plus a 4.6 sqm deck), offering three design options within the same efficient footprint.
• Pomona 112: 58.5 sqm of total living space (46.1 sqm living plus a 12.4 sqm deck) - an efficient, low-maintenance layout with a larger deck than most of the range.
• Hamilton 112: 70.3 sqm of total living space (55.8 sqm living plus a 14.5 sqm deck) - the most spacious one-bedroom option, suited to a granny flat brief that needs a little more room to live in full-time.

Budget certainty matters most on a smaller project, often the first modular home a client builds. Saltair's granny flat and small home designs come with the same fixed-price model as every design in the range - once your design and inclusions are locked in, the price doesn't move. Saltair is also a CommBank-assessed manufacturer, which can help unlock better finance conditions for your build - speak with our team or your lender about what's available for your project.
