Pergola, Patio or Alfresco? Choosing the Right Outdoor Structure

The words get used interchangeably and they should not be, because they describe genuinely different structures with different costs and different approvals.

Pergola

An open structure with a slatted or open roof, or no roof at all. Traditionally for growing plants over, now often fitted with adjustable louvres.

Provides: dappled shade, structure, a sense of enclosure. Does not provide: rain protection, unless roofed. Cost: $250 to $500 per square metre for timber. Louvred aluminium systems run $700 to $1,300. Approval: often exempt if small and detached.

Good for defining an outdoor space and taking the edge off summer sun. Not somewhere you sit during a Hunter downpour.

Patio

A roofed structure, usually attached to the house, over a paved or concrete area at ground level.

Provides: full weather protection, year-round usability. Cost: $350 to $700 per square metre. Approval: generally needs a CDC once attached to the house.

The workhorse option. Most of what people actually want when they say pergola is really a patio.

Verandah

Roofed, attached, and traditionally running along one or more sides of the house, often integrated under the main roofline.

Provides: weather protection plus a genuine architectural relationship to the house. Cost: $500 to $900 per square metre. Approval: CDC or DA depending on extent.

Suits older and character homes where a bolt-on patio would look wrong.

Alfresco

An outdoor living area integrated under the main roof of the house, usually with the same ceiling lining, lighting and often the same floor level.

Provides: the most seamless indoor to outdoor connection. Cost: $900 to $1,600 per square metre. Approval: part of the building approval, DA or CDC.

Usually designed in at build stage, though it can be retrofitted as part of an extension.

Which one to choose

You want shade over a courtyard and like plants. Pergola.

You want to use the space when it rains. Patio, at minimum.

You want an outdoor room that feels like part of the house. Alfresco.

You have a character home and want it to look original. Verandah.

You want the outdoor kitchen and the big table. Patio or alfresco, with power, lighting and enough roofed area to fit the table plus circulation.

The detail that decides whether you use it

Roof pitch and overhang. Too shallow and driving rain comes in sideways. West-facing spaces need more overhang or a screen for afternoon sun.

How the new roof meets the old. This junction is where leaks come from. It has to be flashed properly, not sealed with silicone.

Drainage. A new roof adds catchment. Your existing gutters and stormwater may not handle it. This gets missed constantly.

Level threshold. Matching the internal floor level makes the space feel like part of the house. It also needs careful waterproofing at the junction.

Insulated roofing. Standard steel roofing radiates heat and is loud in rain. Insulated panel costs more and transforms usability.

Size

The most common regret is building it too small. A table for six plus chairs pulled out needs roughly 4 metres by 4 metres. Add a lounge setting and you want 6 by 4.

Measure your furniture, allow circulation, then add a metre.

We build all of these across Newcastle, Lake Macquarie and the Hunter, and will tell you honestly which one fits how you plan to use the space.
