Second storey extension to a Gold Coast home, completed by All Leonard Build.
Extensions

More space. Same street. Same home, only better.

Extensions are our specialty. Ground floor additions, second storey lifts, master suites and family wings, designed to extend the home you already love, not replace it. We've spent two decades doing this on Gold Coast blocks, including the tricky ones.

What it is

An extension lets you stay in the suburb, school catchment and street you've chosen, while gaining the room a growing family actually needs. Most of our extensions add a master suite, an upstairs living area, or a ground floor family wing that opens to the yard.

Common questions

The questions clients actually ask.

  • We use a tool called ProCalc to give you realistic budget guidance within 24 hours of our consultation. It's not a final quote, it's an honest range so you can decide whether to go further before anyone spends real money.

  • Yes. A lot of Gold Coast hinterland and acreage blocks aren't flat, and most of our extension work involves engineered footings, retaining or split level tie ins. We've done plenty, we'll tell you straight if a block is genuinely too tough.

  • A renovation reworks what's already there. An extension adds new floor area, a new room, a new wing, or a whole second storey. Many of our projects are a combination: extend the footprint, then renovate what's left.

  • Almost always, yes. We handle the lot, town planning, building approvals, engineering and certifications, so you don't have to chase paperwork. We'll flag anything unusual before the quote is signed.
