Renovations & extensions · Brisbane

Build once. Build properly.

Extensions, raise-and-build-unders and whole-house renovations across Brisbane’s north-west, run by a named site manager who’s on your site from the first stump to the final coat of paint.
Send us drawings if you’ve got them, photos if you haven’t. A fixed-price quote follows a proper site survey, and both cost nothing.

    What we build

    Three jobs we know inside out

    Extensions

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

    Raise & build under

    Lifting a Queenslander onto new stumps and building a proper level underneath — laundry, rumpus room, another bedroom — to council and engineering approval.

    Full renovations

    Whole-house rewires, replumbs and rooms rethought, phased so you can stay living in the house if that suits.
    Why Stonebridge

    The price that doesn't move.

    Most building horror stories 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. Ours doesn’t work that way.
    Fixed price The quote is the price. Changes only move it if you change the job.
    Named site manager One person, one phone number, on your site from day one to handover.
    Weekly photo updates Every Friday: photos, progress against the schedule, and what happens next week.
    Home warranty covered Residential work over $3,300 carries QBCC’s statutory Queensland Home Warranty Insurance, alongside our own 10-year structural guarantee — not a private warranty standing in its place.

    How a build runs

    Three phases, one Friday email

    Survey & fixed-price quote

    We survey properly — floors up, walls probed where we can — then quote a price that doesn’t move once you’ve signed.

    The build, managed

    Your named site manager runs the trades, the deliveries and the inspections, and emails you every Friday.

    A walkthrough, a snag list cleared within a fortnight, and the 10-year structural guarantee in writing.

    What clients say

    “The weekly photo email became the family’s Friday ritual. We watched the extension happen from across town while we were staying with family.”
    Diane P.
    THE GAP
    “Fixed price meant fixed price. Nothing moved except the one change we asked for ourselves.”
    Warren B.
    ASHGROVE
    “Raising the house felt like the scary part going in. It turned out to be the smoothest week of the whole job.”

    Where we work

    Brisbane's north-west

    We keep the radius tight around The Gap, Ashgrove, Enoggera and Mitchelton, so your named site manager is never far from site.
