Home extensions in Brisbane & the Gold Coast
We design and build ground-floor and upper-floor home extensions that integrate seamlessly with your existing home — managing the entire process from initial design through council approval, structural construction and finished interiors, under a single contract.
When is an extension the right solution?
A home extension makes sense when you love your location, your land and your neighbours but need more space. Whether you are a growing family that needs additional bedrooms, a professional who needs a home office, or an empty nester looking to create a guest suite, an extension is often more cost-effective and personally satisfying than selling and buying a larger property in a competitive SEQ market.
One of the most important aspects of a successful extension is how it connects with the existing home. Our designers ensure that every extension we build feels like it was always part of the home.
Ground floor & upper floor additions
Living Extensions
Opening up the back of the house to create open-plan kitchen, dining and living areas.
Bedroom Additions
A new master suite with ensuite and walk-in wardrobe, or additional bedrooms for a growing family.
Home Office & Studio
A dedicated workspace or studio separated from the main living areas.
Upper Floor Additions
Adding a level to double usable floor area — our structural team assesses and reinforces the existing structure.

What a home extension costs
Extension cost depends on complexity, finishes and site conditions. Upper floor additions are generally priced higher due to structural requirements.
| Scope | Indicative range |
|---|---|
| Ground floor extension | $2,500 – $4,500 / m² |
| Upper floor addition | Priced higher — structural |
| Character / Queenslander extension | Priced by scope |
