Sunshine Coast's Trusted Home Extension Experts

A successful home extension requires more than just adding space. It needs to feel like a natural part of your home, both visually and structurally. At Reynolds Built, we specialise in seamless integration, ensuring your extension improves how your home functions.


We work on a wide range of extension projects, including:


  • Living room & open-plan extensions
  • Additional bedrooms & guest spaces
  • Kitchen & dining extensions
  • Second-storey additions
  • Outdoor living areas & alfresco spaces


From foundation work through to finishes, we consider airflow, natural light and layout to ensure the new space enhances comfort and usability. On the Sunshine Coast, homes are often designed to maximise indoor-outdoor living. Our extensions reflect this, creating spaces that connect with outdoor areas while maintaining protection from the region's heat, humidity and storms.


Reynolds Built delivers extensions that are built to last.

Frequently Asked Questions

How much does a home extension cost on the Sunshine Coast?

The cost of a home extension on the Sunshine Coast varies depending on the size and complexity of the addition, structural requirements, site conditions, access, level of finishes and how the new space connects with the existing home.

Rather than relying on a generic square-metre rate, Reynolds Built assesses each project individually to provide a detailed quotation based on the actual scope, design and requirements of your extension.

How long does a home extension take?

The timeframe for a home extension depends on the size and complexity of the project, structural work involved, site conditions and level of finishes.

Before construction begins, time also needs to be allowed for design development, engineering, selections and relevant approvals. Once the plans and scope are established, Reynolds Built can provide a clear construction timeframe and keep you informed throughout the project.

Do I need council or building approval for a home extension on the Sunshine Coast?

Most home extensions will require building approval, while planning or other approvals may also be required depending on the property, location and proposed works.

The requirements are specific to each project. Reynolds Built can help you understand the likely approval pathway and work alongside the relevant building designer, engineer and certifier to help ensure the necessary documentation and approvals are in place before construction begins.

Can I add a second storey to my existing home?

In many cases, yes. Whether a second-storey extension is suitable will depend on the existing home's structure and foundations, the proposed design, site constraints and relevant planning and building requirements.

Engineering and design are important parts of determining what is achievable. Reynolds Built can assess your project and work with the relevant professionals to establish a practical pathway for adding another level to your home.

How do I know whether to extend out or add a second storey?

The best option depends on your property, existing home, available land, desired floor plan, site constraints and budget.

Extending out can be a practical solution where there is sufficient space, while adding a second storey can allow you to significantly increase your home's floor area without reducing valuable outdoor space. Reynolds Built can help assess both options and determine which approach is best suited to your home, lifestyle and project goals.
