Should I renovate or knock down and rebuild?

It depends on your home's structure, heritage status, the extent of changes needed and your budget. Generally, if renovation costs exceed 50 to 60 percent of rebuild cost, rebuilding may make sense. We can help you analyse both options realistically.

How much contingency should I budget for a renovation?

A contingency of 15 to 20 percent is commonly suggested for renovations. Older homes often have surprises like asbestos, outdated wiring, termite damage or structural issues. Better to have contingency and not need it than be unprepared.

Do I need council approval for renovations?

Most structural changes require development approval. Internal changes may not need approval unless they affect load-bearing walls or services. We help you understand what requires approval and navigate the process.

How do I find a good renovation builder?

Look for builders who specialise in renovations, not just new homes. Check references specifically for renovation work. We maintain relationships with Adelaide's best renovation specialists and can make recommendations.

What if I find asbestos during my renovation?

Asbestos is common in Adelaide homes built before 1990. Removal must be done by licensed removalists. Costs vary depending on extent. A pre-renovation asbestos assessment can prevent mid-project surprises.

Can you help if my renovation has already gone wrong?

Yes. We help homeowners navigate renovation disputes, assess variation claims and find completion builders if needed. It's never too late to get expert help.

Real Adelaide Story

How We Helped the Boutros Family Bring Their Extension to Life

Boutros Family • Home Extension • Adelaide, SA

The Situation

The Boutros Family wanted to extend their home but were struggling to find a builder willing to take on the project. They also found it hard to visualise what the finished extension would actually look like.

The Challenge

After approaching multiple builders with no luck, they were losing confidence in the project. Without clear visuals, it was difficult to commit to a design direction or feel certain about the investment.

Our Approach

We helped them visualise the extension with clear design guidance and connected them with a builder from our network who was the right fit for the job.

The Result

The Boutros Family moved forward with confidence. Their extension was completed smoothly, and the result matched exactly what they had envisioned.

Local Expertise

Renovation Expertise Across Adelaide

We specialise in helping homeowners renovate Adelaide's older housing stock.

Inner Adelaide

Unley • Norwood • Prospect • North Adelaide • Walkerville • Burnside

Character homes with heritage considerations. Often have asbestos and structural complexities.

Eastern Suburbs

Magill • Campbelltown • Rostrevor • Paradise • Athelstone

Post-war homes often needing modernisation. Good bones but dated layouts.

Western Suburbs

Henley Beach • Grange • Fulham • Lockleys • West Lakes

Mix of periods. Coastal properties need specific material considerations.

Southern Suburbs

Blackwood • Belair • Mitcham • Panorama • Colonel Light Gardens

Many 1950s to 70s homes. Often have good structure but poor layouts.

Council Requirements

Adelaide Council Requirements for Renovations

Renovation requirements vary significantly across Adelaide councils. Understanding your council's rules early saves time and money.

Character Areas

Unley, Burnside, Norwood Payneham & St Peters

Strict character overlays may limit external changes. Front facade alterations often require Development Approval even for minor works.

Heritage Zones

City of Adelaide, Prospect, Walkerville

State or local heritage listing requires additional approvals. Changes must be sympathetic to original architecture.

Standard Metro

Marion, Salisbury, Tea Tree Gully, Charles Sturt

More flexibility for renovations. Internal changes rarely need approval. Extensions follow standard planning rules.

Hills & Rural

Adelaide Hills, Mount Barker, Alexandrina

Bushfire compliance may be required for additions. Native vegetation clearance rules apply. Steeper blocks need engineering.

Before You Commit

What People Often Overlook When Renovating

After guiding many Adelaide renovations, we see the same oversights repeatedly. Here's what catches most homeowners off guard.

Renovation builders aren't the same as new home builders

Renovations require different skills: working with existing structures, managing surprises, and minimising disruption. Many new home builders struggle with renovation complexity.

What you can't see usually costs the most

Behind walls and under floors is where the real costs hide: outdated wiring, asbestos, termite damage, and inadequate framing. Always assume there will be surprises.

Council requirements vary dramatically

What's approved in one council area may be rejected in another. Character overlays and heritage zones have strict rules that can limit your options.

Scope creep is almost inevitable

Once walls are open, you'll see opportunities (and problems) you didn't plan for. Having contingency and flexibility in your budget is essential.

Living through a renovation is harder than you think

Dust, noise, tradies at 7am, no kitchen for weeks. It takes a toll. Plan for disruption and have realistic expectations about the process.

Cheap quotes often lead to expensive projects

The lowest quote is rarely the best value. It often reflects missed scope, unrealistic assumptions, or a builder who'll make it up on variations.
