Extensions · raise & build under · renovations

Build once. Build properly.

Stonebridge builds extensions, raise-and-build-unders and whole-house renovations across Brisbane’s north-west — fixed-price, with a named site manager on site from the first stump to the final coat of paint.

Why fixed price matters

The horror stories all start the same way.

An estimate instead of a quote. A start date instead of a schedule. A ‘we’ll sort that later’ instead of a drawing. Every building nightmare you’ve heard began with something vague.

We remove the vagueness before the skip arrives: fixed price, named site manager, weekly photo updates, and a schedule you can hold us to.

What we build

Three jobs we do every week.

Different shapes, same discipline.

Extensions

Single and double storey, wraparounds and side returns — from footings to the final coat of paint, one contract.

Raise & build under

New stumps, a lifted house and a proper level underneath: laundry, rumpus, another bedroom, to engineering and council approval.

Full renovations

Whole-house rewires, replans and refits — lived-in or empty, phased so the chaos has a calendar.

What they say after handover.

“The weekly photo email became the family's Friday ritual. We watched the extension happen from across town while we were staying with family.”

“Fixed price meant fixed price. Nothing moved except the one change we asked for ourselves.”

“Raising the house felt like the scary part going in. It turned out to be the smoothest week of the whole job.”

Raise and build under

That extension isn't going to build itself.
