Patios structures can be constructed in many ways and they are a cost-effective way to add to your living space. Aluminium patios are more expensive but aluminium dissipates heat well so the underside stays relatively cool. Colourbond sheeting is formed from steel and tends to retain the heat and therefore get warmer underneath. Both of these options do not offer light so in some cases can darken the inside of your house if they are over a window or a door. Polycarb sheeting can be substituted for either aluminium sheets or Colourbond sheets to allow light to enter the house and brighten things up inside.

For this option, plans are required and in some cases an engineers certificate.
