What size furniture fits a standard granny flat?

Most small second dwellings are 60 square metres or under, so furniture scaled for a two-bedroom apartment — a two-seater sofa rather than a sectional, a small dining table rather than a six-seater — tends to fit better than furniture bought for a full-sized house.

Is it cheaper to furnish a granny flat secondhand than new?

Generally yes, and the saving compounds because a granny flat needs a full set of furniture categories (bed, seating, table, storage) in one go, rather than one or two pieces at a time.

Can a granny flat be rented out separately from the main house?

Yes — a small second dwelling can be rented to anyone, including someone unrelated to the household, but it can't be subdivided or sold separately from the main home.

What furniture should I prioritise first in a small second dwelling?

Bed or sofa bed and storage, since those are hardest to retrofit later. Dining and living furniture can be added once you know how the space is actually being used day to day.

Do I need a building permit even for a small granny flat?

Yes. A building permit is required for a small second dwelling regardless of its size or planning permit exemption status.

What's the difference between furnishing for family versus furnishing to rent?

Furnishing for family generally prioritises comfort and familiarity (a proper bed, softer furnishings); furnishing to rent prioritises durability, neutral styling and easy cleaning for turnover between tenants.

Is secondhand furniture safe to buy for a granny flat kitchenette?

Check hard surfaces (benchtops, cabinetry) for wear and confirm any appliances work before pickup — the same due diligence as buying secondhand furniture for any room.

Will compact granny flat furniture be easy to resell later if I don't need it anymore?

Usually — compact and multi-functional pieces are in steady demand across apartments, studios and small rentals, so they tend to sell on more easily than oversized furniture bought for a full house.

Can I mix secondhand furniture with a few new pieces in a granny flat?

Yes — many people furnish most of the space secondhand and buy new only for specific items like mattresses or window coverings sized to unusual dimensions.

Granny Flat Furniture Melbourne: A Secondhand Guide to Furnishing a Secondary Dwelling

Q: Do I need a planning permit to build a granny flat in Melbourne?

In most cases, no. A small second home up to 60 square metres no longer requires a planning permit in most cases where there are no flooding, environmental or other special planning controls, per Planning Victoria. A building permit is still required regardless of size.

Furnishing a granny flat or backyard studio in Melbourne doesn't need a full-price shopping trip. Here's how to furnish a small second dwelling well — and secondhand.

If you're searching for granny flat furniture in Melbourne, you're probably staring at a floor plan that's smaller than your current lounge room and wondering how a bed, a couch, a table and a kitchen are all meant to fit. It's a fair question. A small second dwelling — the official term now used across Victoria — asks more of every piece of furniture in it than a full-sized house does, and buying everything new for a space you might only use for a season or two rarely makes sense.

Victoria has made these builds significantly easier to get approved. Following Amendment VC253, a self-contained small second home up to 60 square metres — with its own kitchen, bathroom and toilet — no longer requires a planning permit in most cases where there are no flooding, environmental or other special planning controls, according to Planning Victoria. A building permit is still required regardless of size, and it's worth confirming that step directly — the Victorian Building and Plumbing Commission sets out what a compliant small second dwelling needs to include, from a bathroom and toilet to a kitchen and laundry facilities.

Why granny flats are having a moment in Melbourne

Multi-generational living isn't a niche arrangement anymore. Household composition across Australia has been shifting for years, and the Australian Bureau of Statistics projects the total number of Australian households will keep climbing well past 13 million by 2046, with a growing share of people living in shared or multi-person arrangements rather than alone. In Melbourne specifically, that plays out as adult children staying home longer, parents moving in with their kids, and backyards turning into rental studios or home offices. A secondary dwelling lets a household add space without selling up or extending the main house — which is exactly why councils across Melbourne report a steady stream of small second dwelling applications since the 2023 reform.

Whatever the reason for building one, the furnishing brief is different from a normal house. Everything needs to be smaller, more flexible, and — because a granny flat is often a transitional space rather than a forever home — not worth spending full retail price on.

What actually needs to fit in a granny flat

A 60-square-metre small second dwelling typically has to accommodate:

A sleeping area (bed or sofa bed)
A living/dining zone that often doubles as both
A kitchenette or full kitchen
Storage that doesn't eat floor space
Sometimes, a desk or study nook

That's a full household's worth of function packed into roughly the footprint of a two-bedroom apartment. Furniture bought for a family home — a six-seat dining table, a deep sectional, a chest of drawers built for a walk-in wardrobe — usually won't fit, and buying new pieces scaled specifically to a granny flat's dimensions can get expensive fast when every item is purpose-bought.

Before you buy anything, it's worth measuring more than just the room and the doorways. Delivery access — side gates, narrow paths, steps, or a deck the furniture has to cross to reach the granny flat — can rule out a piece that would otherwise fit the room perfectly, so check the full path from the street to the door, not just the final opening.

Why secondhand furniture suits a secondary dwelling

This is where secondhand does more than save money — it's genuinely a better fit for how granny flats get used. A few reasons:

Sizing varies naturally. New furniture ranges are produced in a handful of standard sizes. Secondhand listings vary piece to piece, so it's realistic to find a sofa, table or bed that's a size down from standard retail dimensions — useful when every centimetre of a small second dwelling counts.
The use case is often temporary. A granny flat might house a parent for a couple of years, a young adult saving a deposit, or a long-term tenant. Furnishing it secondhand keeps the outlay proportional to how long it'll actually be used, rather than locking in a full-price fit-out for a room that might get repurposed later.
Multi-functional pieces show up often in secondhand listings. Sofa beds, extendable tables, and storage ottomans get sold on by people upgrading or moving — which means there's a steady supply of exactly the kind of furniture a compact dwelling needs.
It resells well if the granny flat's purpose changes. Compact, multi-functional furniture is in demand well beyond granny flats — it suits apartments, studios and small rentals across Melbourne. If the space later becomes a home office, a teenager's room or goes back to storage, well-chosen secondhand pieces are easy to sell on rather than write off, which keeps them circulating instead of heading to landfill.
It's aligned with why people build granny flats in the first place. A build driven by housing affordability pressure sits oddly next to a full-price furniture fit-out. Furnishing secondhand keeps the whole project consistent with the reason it exists.

None of this rules out buying new where it genuinely makes sense — a mattress you're unsure about the condition of, for instance, is worth checking carefully rather than avoiding secondhand altogether (see our pricing guide for how to judge condition and value).

Furnishing for family vs furnishing to rent

The furniture brief changes depending on who the granny flat is for.

Furnishing for a family member — a parent, an adult child, an in-law — tends to prioritise comfort and familiarity. A proper bed rather than a sofa bed, a recliner if mobility is a factor, softer lighting, and pieces that don't feel like a hotel room. If the occupant is downsizing out of a larger home into the granny flat, our downsizing furniture guide covers how to decide what makes the move and what doesn't.

Furnishing to rent out takes a different approach: durable, neutral, easy to clean, and flexible enough to suit whoever moves in next. Think laminate over upholstered where floor traffic is high, and furniture that photographs well for a rental listing. Either way, the same secondhand principle applies — you're not trying to impress anyone with brand names, you're trying to fill the space well.

If the granny flat doubles as a work-from-home studio rather than a bedroom, a fold-down desk and an ergonomic chair matter more than a bed — our secondhand home office guide covers desk and chair dimensions worth checking before you buy.

New vs secondhand: furnishing a granny flat

	Buying new	Buying secondhand
Cost for a full fit-out	Full retail across every category	Typically a fraction of retail, per-item
Sizing options	Limited to current retail ranges	Wide range of sizes and eras available
Lead time	Weeks for delivery on made-to-order pieces	Often available for pickup same week
Fit for temporary/transitional use	Locks in full cost for uncertain duration	Outlay scales with how long you'll actually use it
Resale if the space's purpose changes	Depreciates fast, hard to move on	Compact/multi-functional pieces resell well
Environmental footprint	New manufacturing, packaging, freight	Furniture already in circulation, kept out of landfill
Best for	A permanent, fully custom-built space	Most granny flat, backyard studio and secondary dwelling setups

Move-in furniture checklist

Bed or sofa bed sized to the actual room dimensions (measure before you buy — not after)
Small dining or drop-leaf table that seats 2–4
Compact seating — armchair, loveseat or two-seater rather than a full sectional
Storage that uses vertical space (wall shelving, a tallboy) rather than floor footprint
Kitchenette essentials if not built-in: a small table, stools, freestanding storage
Window treatments sized for smaller windows
Task lighting — small second dwellings often have fewer ceiling points
A desk or fold-down work surface if the space needs to double as an office
Delivery access checked — gates, side paths, steps and decks, not just doorways

Where to find granny flat furniture near you

Because a small second dwelling is built on the same title as the main house, furnishing one is usually a local job — you're moving furniture a few metres, not across the city. Searching secondhand listings in your own suburb, rather than city-wide, makes pickup logistics far easier. If you're in the southeast, secondhand furniture listings in Ormond are a reasonable starting point, and Zirkly's Melbourne secondhand furniture hub covers listings across the wider metro area if you need to widen the search.

Conclusion

A granny flat furniture Melbourne search usually starts with a floor plan and a budget that don't quite match what full-price retail offers. Furnishing a small second dwelling secondhand solves both problems at once — smaller sizing options, lower cost per item, and furniture that suits a space that might be used differently in a few years' time. Whether you're furnishing for a parent moving closer, an adult child staying home a little longer, or a studio you're planning to rent out, the same rule holds: measure first (including how furniture actually gets to the door), buy secondhand where you can, and keep the fit-out proportional to how the space will actually be used.
