Frequently Asked Questions

  • What is the difference between an extension and a renovation?

    An extension adds additional floor space to a property, increasing its square footage. It is often more costly due to its complexity and need for additional functions, plumbing and electrical work.  Extensions, due to their scale and structural changes, also often require you to obtain council approvals or building permits before work can begin. 


    A renovation, on the other hand, means undertaking upgrades of an existing space within the home, meaning the square footage of the house remains unchanged. Renovations are less costly than extensions and typically do not require council approvals or major permits.


  • How much does a ground-floor house extension cost?

    That’s a tricky one, because the cost really depends on a few things, like the size and nature of the space, the materials you choose, whether you need extra plumbing or electrical work, and any special features you want.

  • Do you offer modular home extensions?

    Yes, we do. They are a smart option if you’re looking to add space without all the usual fuss of on-site construction and building logistics. The modules are built off-site and then delivered and installed at your home, which means less disruption for you and a faster, smoother build.

  • Do you do side-of-house extensions?

    Absolutely, we do! Side-of-house extensions are a great way to add extra living space, such as a larger kitchen, living room, or even a whole new bedroom or granny flat.

  • Can a modern extension blend in with my older style house?

    Definitely, modern extensions can be designed to complement the character of your existing home. By carefully choosing materials, colours, and architectural details, we can create an extension that feels cohesive with your older house while giving you the benefits of a fresh, contemporary space.
