Entertain in style with a new deck and pergola.

Whether your outdoor space is small or large, having a deck and pergola installed is a great way to make the most of the area you have, and the allenCO construction team can do it to a budget that suits your requirements.

Our warm Australian weather and love for the outdoors has evolved to bring the inside out with mounted TVs, luxurious lounges, fire pits or fireplaces, fancy or smart tech string lights, and functional outdoor kitchens, all brought together by an entertaining space that becomes a much-loved and well-used extension of the home. And beautifully complementing your deck and pergola with clever landscaping choices can also further increase its value.

Considering how you utilise your current space is essential in creating the most ideal outdoor entertaining area for you and your family.

Our team of qualified carpenters and builders will consult with you to determine your preferred style, size, shape, roof pitch, and materials to create a space you love to come home to and will stand the test of time.

How much will a new deck and pergola cost?

Determining the cost of a deck and pergola is as the saying goes “How long is a piece of string?

While these lists aren’t exhaustive, there are many factors to consider when designing a deck and pergola to suit the needs of your family and your budget, like:


  • Site and excavation costs
  • Materials (Timber / Composite deck / In-built lighting)
  • Railings (Glass panels / Timber / Cable)
  • Type (Freestanding / Attached / Floating / Duel level / Poolside)
  • Size
  • Stairs
  • Use and weight requirements


  • Site and excavation costs
  • Materials (Timber / Metal / Aluminum / Brick & Stone)
  • Type (Traditional / Modern / Freestanding / Attached to house)
  • Roof Style (Open top / Gable or Pitch / Louvered / Cantilever / Transparent / Curved)
  • Roof Materials (Timber / Colourbond / Thatched / Laserlite)
  • Size

Considering these factors, a simple small deck can cost around $4,000 – $7,000, with larger or more elaborate decks including lighting and glass balustrade panels resulting in a total cost of around $10,000.

The cost of a pergola will also vary greatly depending on its size, style, and materials used. An average pergola can cost around $2,000-$2,500 per square metre, with a standard pergola being around the $20,000 mark.

A pergola that is more sophisticated, elegant, and luxurious including things like mounted TVs, a fireplace, and a motorised louvered roof can cost anywhere between $50,000-$60,000 or more.

Anything is possible, there is no limit! (only your budget of course).
