5J Building Is Now Renovating Homes on the Gold Coast
After years of transforming homes across Melbourne, 5J Building is bringing that same standard of craftsmanship to the Gold Coast. We’re proud to now hold a Queensland Building and Construction Commission (QBCC) licence (15633175), meaning Gold Coast homeowners get the same accountable, fully licensed service our Melbourne clients have relied on for years — now with a team who understands the specific demands of building on the coast.
Whether you’re in Surfers Paradise, Broadbeach, Burleigh Heads, Robina, Southport, Palm Beach or anywhere in between, 5J Building is ready to help you renovate.
About 5J Building
5J Building started as a Melbourne-based renovation company, built on a simple idea: deliver quality renovations with honest communication and reliable project management, from first quote to final handover. That reputation is what’s driving our expansion north.
Our move to the Gold Coast isn’t about applying a Melbourne playbook to a different postcode. Coastal building comes with its own challenges — salt air, humidity, cyclone-rated wind loads, and different council requirements through the City of Gold Coast — and we’ve built a local team and local trade network who know how to renovate for this climate, not just around it.
We’re now QBCC licensed to carry out residential building work in Queensland, and every renovation we take on here is backed by the same project management, transparent quoting, and quality control that built our name in Melbourne.
Our Services
5J Building offers full-service home renovations for Gold Coast homeowners, including:
- Kitchen renovations — from a refresh to a full reconfiguration, designed for open-plan coastal living
- Bathroom renovations — including waterproofing and fittings suited to humid, high-salinity conditions
- Home renovations and extensions — additional living space, second-storey additions, and whole-home makeovers
- Outdoor living and alfresco renovations — decks, alfresco areas, and outdoor kitchens built to withstand coastal weather
- Older home renovations — updating character homes and post-war builds common across Gold Coast suburbs
Every project starts with a clear scope and fixed quote, so you know what you’re paying for before work begins.

Frequently Asked Questions from Gold Coast Customers
Is 5J Building licensed to work on the Gold Coast?
Yes. 5J Building holds a current QBCC licence (15633175), which covers residential building work across Queensland, including the Gold Coast. You’re welcome to verify this directly with the QBCC before engaging us.
Which Gold Coast suburbs do you service?
We currently service the Gold Coast region, including Surfers Paradise, Broadbeach, Burleigh Heads, Robina, Southport, Palm Beach, Mermaid Beach, and Coolangatta. If you’re just outside these areas, get in touch — we may still be able to help.
Do I need council approval to renovate my Gold Coast home?
It depends on the scope of work. Structural changes, extensions, and some bathroom or plumbing work typically require approval through the City of Gold Coast, while cosmetic renovations often don’t. We handle the approval process as part of our project management, so you don’t have to navigate it yourself.
How is renovating on the Gold Coast different from other regions?
Coastal conditions mean higher humidity, salt exposure, and in some areas, cyclone-rated wind load requirements under the Queensland Development Code. We select materials, waterproofing, and fixings accordingly, rather than using standard inland specifications.
How long does a typical renovation take?
Timelines vary by project scope — a bathroom renovation might take 3–4 weeks, while a full home renovation or extension can run several months. We provide a project timeline as part of your fixed quote, before any work begins.
Do you offer fixed-price quotes?
Yes. Every renovation starts with a clear, itemised, fixed-price quote, so there are no surprise costs once work is underway.
