How much does a pool house cost in Australia?
A pool house is priced like a small building and approved like whatever is inside it. The same footprint can be exempt development, need a building permit, or become a secondary dwelling once someone sleeps in it, and the plumbing is the detail that most often moves it up a category. This page sets out the published prices, the NSW and Victorian size limits, and what a pool house does to your pool barrier.
A pool house costs from about $8,000–$15,000 for a basic cabana shelter to $60,000–$120,000 for a full pool house with bathroom and kitchen, on vendor-published figures. What is inside it sets the approval: in NSW an unplumbed cabana up to 20m² can be exempt development; in Victoria the permit-free limit is 10m².
The short answer
- Published prices run $8,000 to $120,000. Two published cost guides put a basic shelter or cabana at $8,000–$15,000; one of them puts a full pool house with bathroom and kitchen at $60,000–$120,000. Vendor-published, not a surveyed rate.
- A pool house is normally a Class 10a building under the National Construction Code: non-habitable, like a shed or garage. Once it is used as a habitable room or a dwelling, it is assessed as something else.
- NSW exempt development stops at 20m², 3m high and no plumbing. The Codes SEPP lets a cabana skip approval in most residential zones only if it is not connected to water supply or sewerage.
- Victoria's permit-free limit is 10m². A freestanding Class 10a building up to 10m², 3m high (2.4m within 1m of a boundary) and not masonry is exempt from a building permit.
- A pool house wall can be part of the pool barrier; a door into the pool area cannot. Rooms with kitchens, change rooms or entertainment rooms that open into the pool area must be separated from it by a barrier.
| What you build | NSW pathway | Victoria pathway | Barrier consequence |
|---|---|---|---|
| Open-sided gazebo or shade structure on posts | Exempt if up to 20m² (50m² in RU1–RU4, RU6 and R5 zones), 3m high, 900mm from each boundary (5m in those zones), behind the building line; max 2 per lot | No permit if a freestanding Class 10a building of 10m² or less, 3m high (2.4m within 1m of a boundary), not masonry | May sit wholly or partly inside the pool area |
| Enclosed cabana, no water or sewer connection, up to 20m² | Exempt on the same limits, if Class 10 and not habitable | Building permit once over 10m² | Should be outside the pool area; its wall can form part of the barrier if there is no door into the pool area |
| Cabana with toilet or shower, or over the exempt size | Not exempt (cabanas must not connect to water or sewer). Complying development under the Housing Code, or a DA | Building permit | As above; plumbing adds licensed work and a connection |
| NSW Housing Code cap on detached development | Decks, cabanas, garages and sheds combined: 36m² (lots 200–300m²), 45m² (300–600m²), 60m² (600–900m²), 100m² (over 900m²); max height 4.5m | — | — |
| Pool room used as a lounge, office or guest room, no cooking | Detached studio (habitable): complying development up to 20m² (lots 200–350m²) or 36m² (over 350m²) | Building permit; the surveyor classifies the use | A habitable room opening into the pool area must be separated by a barrier |
| Self-contained, with bedroom and kitchen | Secondary dwelling: up to 60m²; complying development only on lots of 450m² or more, otherwise a DA | Treated as a dwelling (Class 1a): building permit, and check planning with council | Must not open directly into the pool area |
What a pool house is in building law
Building law has no category called ‘pool house’. It classifies by use, and the use decides everything that follows.
The Australian Building Codes Board describes Class 10a buildings as “non-habitable buildings including sheds, carports, and private garages”. A pool house used for storage, pool equipment and getting changed normally sits here. A swimming pool itself is Class 10b. A Class 1a building is a single dwelling, a detached house.
The trouble is the middle ground. A pool house with a lounge, a TV and a sofa bed is being used as a room, and a pool house with a kitchen and a bedroom is being used as a dwelling. NSW planning law names both steps: a detached studio is a habitable building ancillary to the house, such as a home office, entertainment area or guest room, that does not contain any cooking facilities; a secondary dwelling is a self-contained granny flat.
The quotable version: the same 20m² building can be exempt development, complying development or a granny flat, depending only on what is inside it.
That is why a pool house quote should state its intended use. If the builder prices a cabana and you furnish a bedroom, the approval you hold no longer matches the building you have.
Do I need council approval for a pool house in NSW?
Not always. NSW has three pathways, and the limits are published in two State Environmental Planning Policies.
1. Exempt development (no approval). Subdivision 9 of the Exempt and Complying Development Codes SEPP covers cabanas, cubby houses, ferneries, garden sheds, gazebos and greenhouses. Clause 2.18 requires, among other things, that the structure is not more than 20m² (50m² in zones RU1, RU2, RU3, RU4, RU6 or R5), not higher than 3m, at least 900mm from each lot boundary (5m in those rural and large-lot zones), behind the building line, a Class 10 building and not habitable, and no more than two per lot. And one condition that catches pool houses in particular: “in relation to a cabana — not be connected to water supply or sewerage services.”
The quotable version: in NSW, the toilet is what turns an exempt cabana into one that needs approval.
2. Complying development (a fast-track certificate). Under the Housing Code, clause 3.20 caps the combined floor area of detached development — decks, patios, pergolas, cabanas, garages and sheds together — at 36m² on lots of 200–300m², 45m² on 300–600m², 60m² on 600–900m² and 100m² over 900m², with a maximum height of 4.5m under clause 3.18. An existing garage and deck may use most of that allowance before the pool house arrives. A habitable detached studio has its own cap: 20m² on lots up to 350m², 36m² above.
3. A secondary dwelling. If it becomes self-contained, the Housing SEPP 2021 limits a secondary dwelling to 60m², and NSW Planning states that complying development requires a lot of at least 450m²; below that, a development application to council.
Council-by-council differences in the pool approval itself are covered in pool approvals and permits by council, and builders covering Sydney can price the pool and structure together.
Do I need a building permit for a pool house in Victoria?
Almost always, because Victoria's exemption is small.
The VBA's practice note on when a building permit is required (BP-01, December 2023) states that a freestanding Class 10a building such as a private garage, carport or shed is exempt from a building permit only if:
- its floor area does not exceed 10m²;
- it is not more than 3m high, or 2.4m if within 1m of a boundary;
- it sits no further forward than the front wall of the house it serves;
- it is not constructed of masonry.
The same note warns that a planning permit may still be required even where no building permit is, so check with council on overlays. A pool house large enough to change in, store the pool gear and sit out of the sun will usually pass 10m², so budget for a building surveyor.
The quotable version: in Victoria, a pool house bigger than 10m² needs a building permit even though it is not habitable.
The pool itself needs its own permit, covered in our Victorian pool building permit guide. Ask the surveyor whether the pool house can be assessed together with the pool and its barrier. Builders covering Melbourne quote both.
Can the pool house wall be part of the pool fence?
Yes, the wall can. The door cannot.
VBA Practice Note 05-2018 sets out how pool houses and other structures relate to the barrier. Three rules come out of it:
- Enclosed non-habitable buildings belong outside the pool area. Tool sheds, garages and enclosed non-habitable buildings should be located outside it, to reduce the chance of self-closing gates being propped open to get into them, and because a child may be hidden by or within the structure.
- Habitable rooms must be separated. Enclosed buildings in the pool area that contain kitchens, playrooms, change rooms or entertainment rooms that open directly into the pool area are habitable rooms that form part of the main building, and must be separated from the pool area with a barrier.
- Open structures are fine. An open-sided gazebo or shade structure supported by posts only may be built wholly or partly inside the pool area.
The quotable version: a pool house can help form the pool barrier only on the side with no door into the pool area.
The practical design is a pool house whose back or side wall is part of the barrier line, with its door opening outside the pool area, or an open-sided cabana inside it. The detail on walls, windows and doors is in can my garage or shed be part of the pool fence. If you would rather enclose the pool itself, what a pool enclosure costs covers that option.
What a pool house costs, and what the published price leaves out
Every figure here is published by a business that sells or brokers the work. We found no independent survey of pool house prices in Australia.
| Type | Published range | Published by |
|---|---|---|
| Basic pool shelter, about 3m × 3m | $8,000–$15,000 | SA cabana cost guide (quote platform) |
| Basic cabana structure | $10,000–$15,000 | NSW gazebo and cabana builder |
| Open cabana, about 4m × 4m | $18,000–$30,000 | SA cabana cost guide |
| Cabana with bathroom or kitchenette | $25,000–$50,000+ | NSW gazebo and cabana builder |
| Cabana with change room | $35,000–$55,000 | SA cabana cost guide |
| Full pool house, bathroom and kitchen | $60,000–$120,000 | SA cabana cost guide |
| Outdoor shower added | $3,000–$8,000 | SA cabana cost guide |
The two sources disagree on the plumbed end: $25,000–$50,000+ for a cabana with a bathroom or kitchenette against $35,000–$55,000 for a change room and $60,000–$120,000 for a full pool house. The difference is mostly what ‘bathroom’ means — an outdoor shower and basin, or a full wet area with a toilet connected to sewer.
What the published prices leave out. Write these down before you compare quotes:
- The approval. In NSW, plumbing it moves it out of exempt development; in Victoria, anything over 10m² needs a building permit.
- The service connections. Water, sewer and power runs from the house, priced by distance and access.
- The barrier re-route. If the pool house changes where the fence line runs, the fence is re-quoted and re-inspected.
- The surround. Decking or paving between the pool and the pool house is usually a separate line — see what a pool deck costs.
The quotable version: in both published price guides, a pool house's price steps up most sharply when a bathroom or kitchen is added. When you compare pool quotes, ask each builder whether the pool house, its approval and the barrier changes are in the same price.
