When a client asks us how long an extension will take, they rarely believe it will be completed in time. It’s a sad reality that builders often over-promise and under-deliver, seeing as unforeseen delays are a reality. When it comes to building a home extension, it’s better to get it right the first time than to rush the process and be left with shoddy results. So how long can you expect an extension to take, and what should you expect from your builder?

First off, if it sounds too good to be true, trust your instinct. A builder who agrees to a due date without asking questions and drafting a plan, is likely to disappoint you. Here’s an example of the process of development foran average extension:


It will take roughly a month to hash out what you want, when you want the project completed, and what your budget will entail. This might seem like a long time, but when you consider how costly it is to fix a mistake once building has commenced, you’ll understand that taking the time tocommunicate on conceptualising and brainstorming your final design is invaluable.


A registeredbuilder won’t even begin to think about starting construction until they have attained all the necessary permits and applications from your local council.Council processes are often slow and frustrating. The process can take anywhere from 6 weeks to 3 months, or even longer. Itis influenced by many factors such as overlays, easements, neighbours, just to name a few, but it’s a step youcan’t rush.A failure to obtain the necessary approvals can result in fines and further delays.


Briefly, the actual extension of your home will start with the construction team preparing the site, first floor and cement base. Once this is completed, the frame will be built, followed by the addition of windows, doors, walls and the roof. Then final touches are completed,like adding skirting and fittings, and only once a final inspection is completed will a building compliance certificatebe issued to declare the extension ready for use. Whilst under permit, the site is under the control of the builder. The process will depend on the building and its structure,and the stages will be set out in your contract and discussed with your builder during the contract process.
