Home Extensions

Need some extra living space at your home? An Altec home extension is the ideal way to take advantage of the unused space in your backyard to add an extra room to your home. Our design consultants are experts at creating stylish new rooms that suit your family’s needs while blending with the original structure.


Your Design, Your Way

Altec has been building home extensions in Brisbane, the Sunshine Coast and the Gold Coast for over 40 years. Our expert team can help you create a custom design that adds value to your property and takes advantage of unused space in your backyard. Whether you want to install an extension that stands out from the crowd or your block has tricky dimensions, no project is too complicated for Altec.

We can build decks, patio, pergolas, carports and boat shelters of all shapes and sizes. Prior to building your patio, our professionally trained designers will walk you through the process of getting council approval and choosing suitable materials for your home extension.

Altec works with a range of colours and hardwearing materials to ensure your extension can withstand Southeast Queensland’s climate. Come rain, hail or shine, your new home extension will be a beautiful space for relaxing and entertaining. We can also include an assortment of smart features in your home extension, including:

  • Insulated and maintenance-free internal ceilings
  • Insulated composite roofing
  • A large range of guttering colours to coordinate with your home
  • Insulated wall panels in a variety of finishes - including Colorbond steel, ply and gyprock - for both inside and outside walls
  • Quality powder-coated aluminium windows in a range of colours
