Expand Your Living Space With Modern House Extensions

If you love your neighbourhood and don’t want to say goodbye, but you/your family have grown since you first moved in, a house extension may be the perfect solution, giving you the extra space you need, while staying in the home and community you love! At KM Build, we love working on house extensions because we get to help families create functional, stylish spaces that grow with them.

Common Types of Ground Floor House Extensions

Thinking about expanding your home, but not sure where to start? Ground floor extensions come in many shapes and sizes, giving you the flexibility to create more space, improve functionality, and enhance your lifestyle. Here are some of the most popular types of ground-floor extensions we work on at KM Build:

Single Room Extensions: 

Expanding a living area to add space without altering the rest of the home.

Kitchen Extensions: 

Enlarging the kitchen footprint, creating open-plan layouts, or adding islands, breakfast bars, and extra prep areas.

Bathroom Extensions: 

Expanding bathrooms to include additional showers, baths, or storage, or creating en-suites with natural light.

Laundry Extensions: 

Increasing space for washing, drying, and storage, adding benches, cupboards, or extra sinks.

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. To learn more about exact costings for both ground-floor and second-story extensions, check out our Consumer Guide. 

  • 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.
