There are many reasons for choosing a knockdown-rebuild over a major home renovation. In many cases, it’s simply cheaper and easier to choose a knockdown-rebuild – particularly if your home is older. In this post, we outline the knockdown rebuild process in 3 simple steps.
1. Check with the council
There’s little point getting excited over a knockdown-rebuild if the local council (or government authority) won’t let you. Most councils have strict rules in relation to knockdown-rebuilds, as they can impact the wider community. If you’re living in a heritage-listed suburb, it’s highly likely that your home
can’t be demolished.
The simplest way to assess whether you can do a knockdown-rebuild is to call the “planning and building” section of your local council. Although council websites usually provide information, it’s best to discuss your requirements with a council specialist
. Provided you’re allowed to do a knockdown-rebuild, a direct call will help you understand what permits and approvals are required.
2. Get expert advice
Once the Council has given you a tentative greenlight, you’ll need to hire an experienced building professional – someone with an in-depth understanding of council regulations and processes
. Such a person could be a structural engineer, a certified town planner or an experienced builder (the one ultimately building your home). Many large national building companies – like G.J. Gardner Homes – provide expert assistance
in this area.
An experienced building professional should not only provide advice, but assist with organising the various permits and approvals required for the project
. As part of their evaluation process, they’ll seek to ascertain the following:
Are there any front boundary setbacks and easements on your property?
Do any council overlays or covenants exist on your property? – these typically relate to heritage, flooding, bushfire and flora protection.
Will the knockdown-rebuild disrupt traffic in your street? – if so, a traffic management plan could be required.
Does your new house design overlook or overshadow any neighbours?
Will the property’s public access point (which could be shared with neighbours) change in any way?
Which utilities (gas, water, electricity, telephone) require disconnection and removal?
Do any large trees require removal? – a separate council permit may be required.
As you’re probably starting to realise, getting expert advice during the early stages of a knockdown-rebuild
3. Organise the demolition
If you’re dealing with a smaller builder, you may be required to find your own demolition contractor. A good small builder will usually refer you to an accredited
demolition specialist – one that’s licensed to conduct demolitions and remove asbestos (if necessary). You’ll be required to provide the demolition specialist with a copy of your demolition permit from the council.
Prior to the demolition, your demolition specialist will need to notify the various utility companies (gas, water, electricity, telephone) of your intentions. It’s imperative to give the utility companies enough time to disconnect and remove their infrastructure.
Once the demolition is under way, it’s the demolition specialist’s responsibility to remove all the waste material – from the house materials
(concrete, timber, metal, glass) to the vegetation (trees, root systems, excess soil). Some demolition specialists will offer to salvage and recycle
the materials being removed – a service that sometimes reduces the demolition cost.
All demolition projects require an Asset Protection Permit (to cover any damage to public property) and a temporary site fence (to protect the public). Once the demolition is completed, your builder can then start preparing the site for construction
