Property developers are actively subdividing blocks across Perth suburbs. Many homeowners wonder whether to demolish the existing house immediately or wait. Demolishing your old structure first provides massive financial advantages. You prevent costly overlapping machine hire. You also streamline essential utility connections. This guide explains how early demolition slashes your overall subdivision costs.
Key Takeaways
- Clearing your site completely prevents paying multiple excavation contractors for overlapping earthworks.
- Licensed surveyors map true land contours much faster without structural obstructions blocking their equipment.
- Early demolition allows clean disconnection of Water Corporation and Western Power utility lines.
- Removing hidden underground footings early prevents expensive delays during the civil construction phase.
Why Should You Demolish Before Subdividing in Perth?
You should demolish before subdividing in Perth to consolidate your siteworks into a single phase. Clearing the block first allows surveyors to establish accurate boundaries for the WAPC. It also exposes hidden underground obstacles before expensive civil construction contractors arrive.
Staging your project correctly dictates your overall profit margins. Leaving an old house standing complicates the surveying process. It also forces earthmoving machinery to maneuver around tight obstacles. This adds expensive hourly rates to your project. Removing the house entirely gives your builders a pristine blank canvas.
Single-Phase Earthworks: Avoiding Double Machine Hire
Earthworks represent a massive portion of your subdivision budget. Hiring excavators and bobcats twice destroys your profit margins. Demolishing first allows you to level the site immediately. We remove old concrete slabs, driveways, and deep tree roots all at once.
You pay one mobilization fee for heavy machinery. You avoid calling contractors back multiple times. This single-phase approach drastically reduces your holding costs. It speeds up your timeline significantly.
Achieving Accurate Site Surveys for WAPC Approval
The Western Australian Planning Commission (WAPC) enforces strict subdivision boundaries. Surveyors must map your exact land contours accurately. Existing buildings physically obstruct surveying equipment. They hide true boundary lines and natural ground levels.
Demolishing the structure first removes these physical barriers. Your surveyor can plot the new lot boundaries perfectly. This prevents boundary design errors that violate council regulations. Fully clearing the block is essential when you want to understand the ins and outs of demolition work and site preparation.
Managing Clean Utility Disconnections
Every Perth subdivision requires upgraded utility connections. You must coordinate with Water Corporation and Western Power. Old houses feature outdated gas, water, and power lines. Demolishing the property allows contractors to cap these lines safely.
Clean utility disconnection prepares the site for new service pillars. You ensure civil contractors do not damage hidden live wires. Damaging active utilities during heavy construction causes massive financial penalties.
Clearing Hidden Underground Obstacles Early
Older Perth homes hide complex underground secrets. You might find buried soak wells, old septic tanks, or massive limestone footings. Discovering these obstacles during the building phase halts construction instantly. Builders charge heavy variation fees for unexpected earthworks.
Early demolition exposes these hidden issues immediately. We rip out deep footings and backfill the soil correctly. We highly recommend reviewing why professional site clean-up matters after demolition to ensure your block is completely builder-ready.
