Demolition and Build Planning (in Perth)
Poor demolition and build planning is where most knockdown rebuild projects in Perth blow out on cost and timing. As an experienced Demolition Contractor, Building Broker Centre provides demolition and build planning that aligns site conditions, council requirements, and construction sequencing before work starts—so your rebuild stays on track from day one.
This planning service is delivered as part of our role as an Building Broker in Perth, helping homeowners coordinate demolition timing, builder engagement, and site readiness before contracts are signed or demolition crews arrive.
Key Takeaways
Demolition and build planning prevents costly sequencing mistakes that delay construction and increase rental holding costs.
Proper planning identifies site constraints, council requirements, and service disconnections before demolition begins, not after problems appear.
A planned demolition phase sets your builder up for a clean site handover, avoiding rework, variations, and construction delays.
What Demolition and Build Planning Actually Covers
Demolition and build planning focuses on the gap between deciding to rebuild and starting construction. Without planning, homeowners face delays caused by missing permits, incorrect demolition scope, poor site preparation, and builders discovering problems only after excavation begins.
Planning aligns demolition works with your future build requirements so the site is cleared, prepared, and handed over in a condition that allows construction to start without interruption.
The Demolition and Build Planning Process
Understanding what drives demolition costs higher helps you budget accurately rather than discovering problems after signing contracts with cheap quotes that miss half the work.
Site assessment – Reviewing access, boundaries, existing structures, slopes, trees, and underground services that affect demolition sequencing.
Demolition scope planning – Defining exactly what must be removed, capped, protected, or retained to suit the future build footprint.
Council and compliance planning – Confirming permit requirements, timeframes, fencing rules, rat baiting, and local council conditions.
Service disconnection coordination – Planning sewer, water, gas, electricity, and telecommunications disconnections in the correct order.
Construction handover readiness – Ensuring the site is cleared, level, compacted where required, and ready for builder mobilisation.
Why Demolition and Build Planning Matters in Perth
Coastal areas such as Scarborough, Marmion, and Ocean Reef also require timing considerations due to wind, sand, and council controls that affect demolition sequencing and site preparation.
Common Problems Planning Prevents:
Builders delayed due to incomplete site clearing or incorrect service capping.
Demolition scopes that miss footings, roots, or underground obstructions discovered during construction.
Council compliance issues that halt works after demolition is complete.
Extended rental costs caused by poor demolition timing or contractor scheduling gaps.
Demolition and Build Planning Costs in Perth
Planning costs are minimal compared to the expense of fixing mistakes during construction. Poor planning commonly adds $10,000–$30,000 in delays, rework, and variations once building starts.
Effective planning protects your total rebuild budget by aligning demolition, site preparation, and builder start dates into a single coordinated timeline.
Who Demolition and Build Planning Is For
Demolition and build planning is suited to Perth homeowners preparing for a knockdown rebuild who want clarity before demolition begins. This service is ideal for families who need certainty around costs, timing, council approvals, and site conditions before committing to demolition contractors or builder contracts.
It is especially valuable for properties with tight access, older infrastructure, sloping blocks, mature trees, or council-specific controls that can affect demolition scope and construction readiness. Homes built prior to the 1990s often carry hidden risks such as asbestos, underground services, or outdated footings that must be identified early to avoid delays and budget blowouts.
Homeowners working with a building broker in Perth benefit from independent, client-side planning that connects demolition decisions with future build requirements. Rather than treating demolition as a standalone task, this approach ensures the site is prepared correctly for the new home design, builder selection, and construction timeline.
If you want a demolition process that supports your rebuild from day one—rather than creating problems later—demolition and build planning provides the structure and foresight needed to move forward with confidence.
Common Build & Planning Questions
Do I need demolition and build planning before choosing a builder?
Yes. Planning before selecting a builder helps identify site constraints, demolition requirements, and council conditions that directly affect build design and pricing. Without this step, builders often discover issues after contracts are signed, leading to delays and costly variations. An example may be a septic system or bore that cannot be dug out. The builder may have to allow for reinforcement into the concrete slab.
What happens if demolition isn’t planned properly?
Simply, things get missed. Poor planning commonly results in incomplete site clearing, incorrect service capping, permit delays, and builders unable to start on time. These issues increase rental holding costs, delay construction, and often require rework that could have been avoided upfront. We have gone as far as having customers place signs on trees or objects that are to stay or be demolished.
Is demolition and build planning only needed for complex sites?
No. While sloping blocks, tight access, or older infrastructure increase the need for planning, even simple sites benefit. Planning ensures demolition aligns with the future build footprint, construction timeline, and council requirements regardless of site complexity.
Does demolition planning help control overall rebuild costs?
Yes. Proper planning reduces unexpected costs by identifying demolition scope, service disconnections, council conditions, and site preparation needs before quotes are obtained. This prevents budget blowouts during demolition and construction. An example may be where Western Power has to be called in to remove overhead power from the home. This could take months, so planning this with them helps rent the old home or allows the occupants to stay in the home longer.
How does demolition and build planning reduce construction delays?
Planning coordinates demolition timing with builder availability, permit approvals, and site readiness. This ensures the site is handed over clean, compliant, and ready for construction—allowing builders to start immediately without waiting on fixes or approvals. Our ideal situation is the old house is demolished this week and the builder is scheduled to start earthworks the week after that!
