Choosing exterior colours for outdoor structures

Colour is one of the first things people notice about a home's outdoor spaces, yet it is often decided last, after the pergola, carport or deck has already been designed. Choosing colours early helps the new structure look like it belongs to the house rather than being bolted on later.

Start with what you cannot change

Roof tiles or sheeting, brickwork, stone and window frames are expensive to alter, so treat them as your fixed palette. A verandah or pergola usually looks best when its posts and beams pick up one of these existing tones, such as matching gutters or window trims, while the roof sheeting either echoes the main roof or sits a shade lighter.

Think about the Australian sun

Dark colours absorb more heat. Under strong summer sun, a charcoal roof over a patio can make the space beneath noticeably warmer than a light grey or off-white one. Darker finishes can also show fading and dust differently from pale ones. Many pre-finished steel products come in colour ranges designed for local conditions, and manufacturers often publish solar reflectance information worth comparing.

Check the rules before you commit

Some councils, heritage areas and strata or estate covenants set limits on external colours, particularly for structures visible from the street. It is sensible to check local planning controls or ask your council before ordering materials. Our FAQ covers common questions about approvals for outdoor structures.

Test in real light

Small swatches look different outdoors than in a showroom. Look at samples at different times of day, beside your brick or cladding, and in both shade and full sun. Morning light, harsh midday glare and evening warmth can all shift how a colour reads.

  • Keep the number of main colours to two or three.
  • Use timber or natural tones to soften metal structures.
  • Consider how the colour will sit with planting as gardens mature.
