Verandah Cost Calculator
Estimate the cost of building a verandah in Australia. Enter the size, choose the roof style and framing, then add flooring and finishing.
Check where the verandah roof meets the existing fascia. If the house has an eave, the new roof either flies over it or the eave is cut back, and flyover framing adds roughly 10 to 15 per cent to the structural cost.
In bushfire prone areas the BAL rating applies to attached verandahs too, which affects decking species, screening and the sheeting you can use. That can add several thousand dollars, so establish your BAL rating before finalising materials.

💰 Ways to save
- Keep the roof a simple skillion. A single sloping roof attached to the existing fascia uses the least material, needs the least framing labour and avoids the ridge and valley flashings that make gable and wraparound designs expensive. The difference between a skillion and a gable of identical area is commonly 25 to 30 per cent, and once the furniture is in most people cannot tell from underneath.
- Build over what you already have. If you have a serviceable concrete slab or a paved area, designing the verandah to sit over it removes the entire flooring line, which is typically 20 to 35 per cent of the project. A pressure clean and a coat of sealer on the existing surface costs a few hundred dollars against several thousand for new concrete or decking.
- Size it to stay within your council's exempt development threshold if you can. Many councils allow a roofed structure under a set floor area, commonly 20 to 25m², and within specified setbacks, without a full development application. Dropping a design from 28m² to 24m² can save two to three months of approval time and $1,000 to $3,000 in application and certification fees.
- Order the lighting and fan wiring during construction even if you fit the fittings later. Running conduit and rough in cabling while the roof is open costs a fraction of retrofitting through a lined ceiling, and a sparky doing it as part of the build charges far less than a separate callout in twelve months.

Understanding verandah costs in Australia
What a verandah costs in Australia in 2026
A verandah in Australia in 2026 generally costs between $8,000 and $35,000, which works out to roughly $350 to $700 per square metre for a straightforward attached structure and $800 or more per square metre for heritage bullnose or wraparound work. A common 25m² skillion verandah with Colorbond roofing, steel posts and an existing slab underneath sits around $9,000 to $14,000. Add new decking, a balustrade, ceiling lining and lighting to the same footprint and you are quickly at $22,000 to $30,000. The structure itself is often the smaller half of the budget once flooring and finishing are included.
Verandah, patio or pergola
The words get used interchangeably and it matters for quoting. A pergola is an open framed structure, sometimes with battens, that provides filtered shade rather than weather protection. A patio is a roofed outdoor area, usually at the rear, generally on a slab. A verandah is a roofed structure attached to the house, typically running along one or more elevations, often with a floor raised above ground and usually with posts along the outer edge. That distinction drives cost, because a raised floor means bearers, joists and stumps, and anything more than a metre off the ground brings a balustrade requirement with it. When comparing quotes, make sure every builder is pricing the same definition.
Roof style is the biggest structural variable
Roof geometry drives framing labour more than anything else. A skillion, a single plane sloping away from the house and fixed to the existing fascia, is the cheapest and fastest to build. A gable adds a ridge, rafters both sides, gable infill and more flashings, generally 25 to 30 per cent above an equivalent skillion. A bullnose, the curved profile associated with Federation and Queenslander homes, uses specialist curved sheeting and fussier framing and prices highest per square metre of any common style. Wraparound verandahs that turn a corner add hips, valleys and corner posts and are effectively two or three structures joined, so they carry both the geometry premium and a longer build.
Flooring, decking and the balustrade trigger
What you stand on can be a third of the total. Using an existing slab or paved area costs nothing beyond a clean. A new concrete slab runs roughly $80 to $150 per square metre supplied and poured. Hardwood decking is around $200 to $350 per square metre supplied and laid depending on species, with merbau and spotted gum at the common end and blackbutt or ironbark higher. Composite decking sits at $250 to $400 per square metre installed but eliminates oiling. The critical technical point is height. Once the finished floor sits more than one metre above the natural ground surface, the National Construction Code requires a compliant barrier of at least 1,000mm with openings that will not pass a 125mm sphere, and that adds $200 to $400 per lineal metre. Designing the floor to sit just under the trigger height, where the site allows, is a genuine saving.
Council approval, setbacks and stormwater
Most verandahs need approval because they are a roofed structure attached to a dwelling. Many councils offer an exempt or complying pathway for structures under a set floor area, commonly in the 20 to 25m² range, provided setbacks from boundaries are met and the structure does not exceed a height limit. Beyond that you are into a development application, which typically costs $500 to $2,000 in fees and takes six to twelve weeks. Engineering certification for the footings and the connection to the existing structure is usually required either way at $600 to $1,500. Stormwater is the requirement people forget. Adding roof area increases the runoff leaving your site, and councils generally require the new gutter to be plumbed to the legal point of discharge rather than discharging to ground, which can mean upsizing downpipes or adding detention on constrained blocks.
Climate, bushfire and regional pricing
Where you build changes both the specification and the price. In Queensland and northern New South Wales, cyclone and wind region requirements push up tie down, bracing and footing sizes, and in declared regions the engineering is not optional. In bushfire prone areas the BAL rating applies to attached verandahs, restricting decking species, requiring ember screening and sometimes non combustible framing, which can add several thousand dollars to an otherwise standard build. Southern states more often add ceiling lining, blinds and heating to extend the usable season. Sydney and Melbourne trade rates sit above Brisbane, Adelaide and Perth for comparable work, and regional jobs can be competitive on labour but carry freight on steel and sheeting.
Take the figure above as a starting bracket, then get three quotes on the same drawing that each state the roof style, the framing material, whether flooring is included, whether engineering and the council application are in scope, and who is connecting the stormwater. Those five items account for most of the spread between verandah quotes.
Frequently asked questions
How much does a verandah cost in Australia?
Typically $8,000 to $35,000, or roughly $350 to $700 per square metre for a standard attached structure. A 25m² skillion verandah with Colorbond roofing over an existing slab runs about $9,000 to $14,000. The same footprint with new decking, a balustrade, ceiling lining and lighting moves to $22,000 to $30,000.
What is the difference between a verandah, a patio and a pergola?
A pergola is open framed and gives filtered shade rather than weather protection. A patio is a roofed outdoor area, usually at the rear and usually on a slab. A verandah is a roofed structure attached to the house, often along one or more elevations, frequently with a raised floor and posts along the outer edge. The definitions matter when comparing quotes because the raised floor and balustrade change the cost substantially.
Do I need council approval for a verandah?
Usually yes, because it is a roofed structure attached to a dwelling. Many councils offer an exempt or complying pathway for structures under about 20 to 25m² that meet setback and height limits. Beyond that a development application typically costs $500 to $2,000 and takes six to twelve weeks, plus $600 to $1,500 for engineering certification of the footings and the connection to the house.
When do I need a balustrade?
Once the finished floor level sits more than one metre above the natural ground surface, the National Construction Code requires a barrier at least 1,000mm high with openings that will not pass a 125mm sphere. That adds roughly $200 to $400 per lineal metre. If the site allows, designing the deck to sit just under one metre avoids the requirement entirely.
Which roof style is cheapest?
A skillion, which is a single plane sloping away from the house and fixed to the existing fascia. A gable typically costs 25 to 30 per cent more for the same area because of the ridge, the double rafters, the gable infill and extra flashings. Bullnose is the dearest common style due to specialist curved sheeting and fussier framing, and wraparound designs add hips, valleys and corner posts.
Does a verandah add value to a house?
Generally yes, particularly in warmer states where outdoor living is a year round expectation, though the uplift is rarely the full build cost. A well proportioned verandah that suits the architecture and connects to a living area tends to return better than an oversized structure that darkens the interior rooms behind it. Poorly detailed additions that block light to bedrooms can read as a negative to buyers.
