Create the extra space your home needs for your Sunshine Coast lifestyle

Looking to extend your home within the Sunshine Coast region?

As families grow and lifestyles change, it’s common for a home to start feeling a little tight on space. Whether it’s a growing household, the need for a larger living area, or simply wanting more room to enjoy your home, extending your property can be a practical solution.


A home extension on the Sunshine Coast allows you to add valuable space without the disruption of moving. Instead of leaving a location you enjoy, you can expand your existing home and create the additional room you need.


At Simplex Building Group, we carry out home extensions across the Sunshine Coast and surrounding hinterland, helping homeowners add space that blends naturally with the existing property.

When a home extension makes sense for your Sunshine Coast home.

Many homeowners reach a point where the house they once felt comfortable in no longer fits their lifestyle. Rather than starting over somewhere else, extending the home can be a far more convenient and cost-effective option.


Common reasons people consider a home extension include:


Adding an extra bedroom

Creating a larger living area

Expanding the kitchen or dining space

Building a master suite

Creating room for a growing family


Extending your home allows you to improve how the property works while staying in the neighbourhood and community you already enjoy.

Adding space without losing the character of your home.

One of the key goals with any extension is ensuring the new space feels like it belongs with the original home. When completed well, an extension should look and feel like it has always been part of the property. This helps maintain the overall character of the home while providing the extra space and functionality homeowners are looking for.


Many Sunshine Coast homes benefit from extensions that improve the connection between indoor and outdoor living areas, creating spaces that feel open and suited to the relaxed coastal lifestyle.

Extensions built for the Sunshine Coast climate

Homes on the Sunshine Coast often benefit from improvements that allow better airflow, natural light and connection to outdoor areas.

Extending a home can provide the opportunity to create more open living spaces, improve ventilation and update areas that previously felt closed off. These changes can make a significant difference to the comfort and livability of the home, particularly in warmer coastal conditions.


We complete home extensions across the Sunshine Coast and nearby hinterland communities, helping homeowners expand their properties while maintaining the style and structure of the original home. Our projects take place throughout the whole Sunshine Coast with suburbs including:

Buderim, Maroochydore, Mooloolaba, Caloundra, Noosa, Bli Bli, Mountain Creek, Peregian Springs, Nambour, Sippy Downs, Warana, Coolum Beach, Montville, Maleny, Mapelton and Palmwoods


Working with experienced home extension builders on the Sunshine Coast helps ensure the new space is constructed properly and integrates smoothly with the existing structure.

Frequently Asked Questions

Is extending a home cheaper than moving?

In some situations it can be. Extending allows you to stay in the same location while gaining additional space, which can avoid the costs associated with selling, buying and relocating.

Will a home extension increase property value?

Additional living space can often increase the overall value of a property, particularly when it improves the functionality of the home.

How long does a home extension take?

The timeframe varies depending on the size and complexity of the extension, but proper planning and experienced construction help keep the process running efficiently. A minimum of 6 months is generally standard for a small extension.

THINKING ABOUT extending your existing home?

If your current home feels a little too small but you don’t want to leave the area you enjoy, a home extension on the Sunshine Coast could be the perfect solution.


Adding space to your existing property can improve comfort, functionality and long-term value while allowing you to stay exactly where you are.
