5. Lengthens the new home build process
If you pick a fresh empty block of land to build your new home, construction can start right away. But if you choose a knockdown and rebuild, there’s the extra time you have to go through of demolishing your existing property.
The first step is getting D.A Approval from your local council. This can take anywhere from three weeks to a few months depending on the size of your home and the complexity of the demolition.
The amount of time this will take differs from house to house, but the largest variable will be the presence of asbestos. The process of going through asbestos removal takes quite a long time, as each panel of your property containing asbestos must be removed by hand. This might only take several hours, but it could also take up to a few days or even weeks depending on the size of your home.
The actual demolition itself can take anywhere up to 10 days. However, demolition letters will need to be sent out to your neighbors (typically 1-2 weeks before work can actually start). You may also need to remove any trees on your block of land before work commences, and this may require the services of an arborist if the trees are particularly big.
Adding the various delay times together means demolishing your home will add a minimum of six weeks onto your build but could easily blow out to a 3-month delay.
