Demolish and Build: Permits, Risks and the Difference to a Standard Home Construction

When it comes to demolish and build, some of the most frequently asked questions are about the required permits, potential risks and the difference to a standard home construction.

In this article we are going to answer all 3 of these questions. Let’s get straight into it and start with the first one.

Do I need to obtain any permits for a demolish and build project?

Yes, obtaining the necessary permits is a crucial step in the demolish and build process.

In Perth, this generally includes a demolition permit to legally remove the existing structure, as well as various building permits for the construction of the new home.

Depending on your specific project and location, additional permits related to zoning, environmental regulations, and heritage preservation may also be required.

Engaging with a knowledgeable builder will help streamline this process, ensuring that all legal requirements are met and avoiding potential delays.

How does the process of demolishing and building differ from a standard home construction?

A demolish and build project involves additional steps compared to standard home construction.

Before the new building process can commence, the existing structure must be safely demolished and the site cleared and prepared, which includes removing debris and potentially rectifying any issues with the land. This initial phase requires careful planning and adherence to safety and environmental regulations. 

There also might be some additional work required regarding utilies and infrastructure before the construction of the new home can begin.

Following this, the process aligns more closely with standard home constructions, involving the design, approval, and building phases.

The key difference lies in the site preparation, with demolish and build projects often presenting unique challenges compared to say a flat, sandy block in a new estate in Perth.

What are the potential risks involved in a demolish and build project?

Knockdown and rebuild projects, like any construction endeavour, come with their own set of risks. These can include unexpected issues arising during demolition. For example if the existing home is very old, it may result in the discovery of hazardous materials like asbestos, which requires specialised removal.

There might also be challenges related to the site itself, including soil stability or drainage issues that become apparent once the existing structure is removed.

To mitigate these risks, it’s imperative to conduct thorough inspections prior to starting, work with an experienced and professional builder, and have a comprehensive risk management plan in place.
