Overview

Home extensions on the Gold Coast are one of the smartest investments a family can make. Instead of selling and paying stamp duty on a bigger home, an extension gives you the extra bedroom, second living space, master retreat or outdoor room your current home is missing - in the suburb you already love. Orange Projects is a QBCC-licensed Gold Coast builder specialising in residential extensions from ground-up single-room additions to full second-storey add-ons. We've delivered home extensions across Robina, Burleigh Heads, Mermaid Waters, Helensvale, Hope Island, Coomera and Southport, working with local designers, engineers and Gold Coast City Council certifiers. Brisbane and surrounding areas are also serviced as a secondary catchment.

Planning your Gold Coast home extension

Every good home extension starts with the right question: what problem is the extension solving? A growing family that needs a fourth bedroom is different from a couple wanting a bigger master and ensuite, which is different again from an entertainer who wants a bigger living-outdoor connection. Orange Projects starts with that conversation on site, then works with your designer or ours to sketch the extension that best solves it. On the Gold Coast, planning also means understanding site constraints - setbacks, height limits, overshadowing rules, easements, slope and access for construction. We do a proper site assessment before design so we don't waste time drawing something that won't get approved. Our familiarity with Gold Coast City Council saves months compared to designing blind.

Structural, engineering and certification

Every home extension on the Gold Coast needs structural design, engineering and building certification - and second-storey extensions add an extra layer of complexity because they load the existing home. Orange Projects coordinates a certified structural engineer, private building certifier and any specialist consultants needed (soil test, energy report, wind classification for coastal sites). We manage the certification pathway from concept design through building approval and final Form 21 sign-off. Where a Development Application (DA) is required - for instance in some overlay zones or for character-listed Gold Coast homes - we coordinate that as well. You never end up chasing a certifier or engineer yourself.

Building around your existing home

Home extensions on the Gold Coast are almost always live-in jobs - the family stays put while the extension goes up. That means the build has to be sequenced carefully to minimise disruption, dust and access issues. We stage work so plumbing, electrical and roof connections happen with the shortest possible break-in period, we install dust barriers where new work meets existing, and we clean up daily so the site is safe for kids and pets. We also match materials to the existing home properly. Rendered brick, weatherboard, colorbond, tile roofs - whatever the original build is, we source matching materials so the extension reads as an integrated part of the house, not a stuck-on addition.

Fixed pricing and program certainty

Extensions have more variables than most renovations because you're integrating with an existing structure. Orange Projects handles that by doing a thorough site inspection - including opening up walls, roof spaces and sub-floors where needed - before quoting. That means the fixed-price quote is genuinely fixed, with variations only for scope changes you agree to. Most single-storey Gold Coast home extensions take 12-20 weeks from site start to handover once approvals are in place. Second-storey extensions typically run 16-28 weeks. We give you a written program up front and photo updates throughout the build.

Frequently asked questions

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

Home extensions on the Gold Coast typically start from around $3,000-$4,500 per square metre for standard single-storey extensions and $4,500-$6,500+ per square metre for second-storey add-ons or premium finishes. A 40sqm single-storey extension is usually $150,000-$220,000, and a full second storey $350,000-$600,000+. Orange Projects provides a fixed-price quote after a site inspection.

How long does a Gold Coast home extension take?

Most single-storey extensions on the Gold Coast take 12-20 weeks on site once approvals are in place. Second-storey extensions typically run 16-28 weeks. Approval and design phases add 8-16 weeks before construction starts, depending on complexity and Gold Coast City Council workload.

Do I need council approval for a home extension in Queensland?

Yes. Home extensions on the Gold Coast almost always require building approval and often development approval, depending on the zone, setbacks and site coverage. Orange Projects coordinates the private certifier, engineer and Gold Coast City Council process end-to-end.

Why choose Orange Projects for a Gold Coast home extension?

We're a QBCC-licensed, fully insured Gold Coast builder with local suburb, certifier and supplier knowledge. Fixed-price quotes, one project manager, premium workmanship and warranty-backed finishing. We match materials to your existing home so the extension integrates properly - not a bolt-on addition.

Can you build a second storey on my existing Gold Coast home?

Yes, in most cases. Second-storey extensions require engineering assessment of the existing footings, wall frames and structural capacity - some homes need underpinning or structural reinforcement before the new floor loads on. We complete that assessment as part of the design phase.

Can I live in the house during the extension?

Most Gold Coast home extensions are live-in jobs. We stage the build to minimise disruption and only require you to relocate temporarily for short critical periods - typically when we're connecting new services or opening the roof to the new area.

What's included in the home extension service?

Design coordination, engineering, certification, all trades (framing, roofing, plumbing, electrical, plasterboard, tiling, painting, flooring, joinery), fixtures, waterproofing where applicable, waste removal, site protection, final clean and QBCC warranty. Every inclusion is itemised in the fixed-price quote.
