The Complete Queensland Renovation Guide: Planning to Handover

Quick answer: a Queensland renovation runs through seven stages - feasibility, design, budget, approvals, contract, construction and handover. Cosmetic work can move from first call to completion in four to eight weeks. Structural work involving engineering and certification typically takes three to eight weeks of preparation before a tool is picked up, then four to sixteen weeks on site depending on scope.

Stage 1 - Feasibility: is this the right work on the right house?

The most valuable hour in a renovation happens before anything is drawn. It is the conversation about whether the money is going in the right place. We regularly walk into homes where the owner wants a $90,000 kitchen in a house whose real problem is a failing rear deck, poor cross-ventilation and a bathroom with water tracking into the frame. Fixing the fabric of the house first protects everything you spend afterwards.

Feasibility means three things: what the house physically allows, what the planning scheme allows, and what the local market will return. On the Gold Coast a well-executed outdoor living upgrade often returns more per dollar than a second bathroom. In inner-Brisbane character suburbs, sympathetic restoration of original detail almost always beats a modern-looking addition at the front of the house.

Stage 2 - Design that respects a Queensland climate

Design in South East Queensland is a climate exercise before it is a style exercise. Orientation, shading, cross-ventilation, eaves depth and the transition between inside and outside determine whether the finished house is comfortable in February. Practical moves that pay off every year: deep eaves or external shading to west-facing glass, ceiling fans in every living and bedroom space, louvres or stacking doors positioned to create a through-breeze, and light-coloured roofing.

• North-facing living areas with controlled winter sun and summer shade
• Cross-ventilation on at least two sides of every main room
• Covered outdoor living that is genuinely usable in rain, not just in photos
• Materials chosen for humidity and, near the coast, salt exposure
• Insulation and sealing upgrades done while walls and ceilings are open

Stage 3 - Building a budget that survives contact with reality

A renovation budget has four parts: construction, professional fees, allowances and contingency. Homeowners typically budget the first and forget the other three. Professional fees - drafting, engineering, certification, energy assessment - commonly run 5 to 10 per cent of construction on structural work. Contingency should be 10 to 15 per cent on a modern home and 15 to 20 per cent on anything built before 1990, because that is where asbestos, undersized framing, termite damage and legacy wiring live.

Understand the difference between a provisional sum and a prime cost item. A prime cost item is a supply allowance - tapware, for example - that you can control by choosing product early. A provisional sum is an estimate for work that cannot be fully scoped yet, and it is where budgets move. Ask your builder to convert provisional sums into fixed prices as soon as the unknowns are opened up.

Stage 4 - Approvals

Cosmetic work is generally exempt. Structural work needs building approval through a private certifier, and planning overlays can add a development application. Our full breakdown of what triggers each approval is in the guide to council approval for Queensland renovations - read it before you lock in a start date, because approvals, not trades, are the usual cause of delay.

Stage 5 - The contract

In Queensland, domestic building work above the QBCC threshold must be under a written contract, and work above the home warranty threshold attracts QBCC Home Warranty Scheme insurance paid by the contractor. Before signing, check: the licensed entity name matches the QBCC register, the scope is itemised rather than described in one paragraph, the progress payment schedule is tied to completed stages rather than dates, the defects liability period is stated, and the variation process is written down.

1. Confirm the QBCC licence number and class on the public register
2. Check the contract price includes home warranty insurance where applicable
3. Read the exclusions list line by line - that is where the surprises hide
4. Agree how variations are priced and approved before work proceeds
5. Confirm site access, working hours, parking and waste handling

Stage 6 - Construction, stage by stage

1. Site establishment, protection of retained finishes, waste and access set-up
2. Demolition and strip-out, including any licensed asbestos removal
3. Structural works - beams, framing, tie-downs, openings, subfloor
4. Services rough-in - plumbing, electrical, data, mechanical
5. Frame inspection by the certifier
6. Waterproofing to wet areas, inspected and certified
7. Linings, cornices, set and sand
8. Cabinetry, benchtops, tiling and flooring
9. Carpentry finishes - doors, skirting, architraves, feature and media walls
10. Painting, fit-off of tapware, fixtures and hardware
11. Clean, certifier final inspection, Form 21, handover

Stage 7 - Handover, defects and documentation

A proper handover is not a set of keys and a wave. You should receive the Form 21, waterproofing certificates, electrical and plumbing compliance certificates, engineering certification where applicable, warranty documentation for appliances and products, and a maintenance note for anything that needs periodic attention - decking oil, seals, filters. Then the defects liability period runs, during which the builder returns to rectify defects at no cost.

The renovations that go badly are almost never the ones with a difficult design. They are the ones where scope was never written down properly at the start.

Renovating specific Queensland housing types

Pre-1946 Queenslanders

Expect character overlay controls in Brisbane, VJ walls that reward restoration, stumps that may need replacing, and original framing in hardwood that is excellent but rarely square. Build in time for discovery.

Post-war lowset brick

Common through Southport, Ashmore and Brisbane's southern suburbs. Usually structurally sound with slab-on-ground floors, small compartmentalised rooms and low ceilings. The highest-value moves are wall removals for open-plan living and reworking the rear of the house to open to the yard.

1990s-2000s project homes

Sound structure, dated finishes. Kitchens, bathrooms, flooring, feature walls and outdoor living deliver the biggest visual change per dollar with minimal structural work and often no approval.

Apartments and townhouses

Body corporate approval sits on top of everything else. Common property, waterproofing membranes, acoustic ratings and lift access all constrain what is possible and when trades can work.
