    There are many different reasons why people decide they want to renovate or extend their current living situation. You may simply want to update the look and feel of your space or improve areas like the kitchen or bathroom for re-sell value. Renovations can aid in making a space feel larger, or mean you can use the space more effectively. If you’re wanting to physically add more space to your home, you may be considering a home extension – adding another whole storey, an extra room or even a granny flat.

    Whether you opt for an extension/addition or renovation, there are multiple pros and cons for both. Your decision also depends on your budget, desired time taken to complete the project, and most importantly, what you want to get out of it – adding more space, reconfiguring, updating the look – whatever it may be, here are the pros and cons for extensions and renovations.

    Renovations: the pros and cons


    • It can increase the value of your home.
    • Typically cheaper than extensions and additions.
    • Less than half the expense will go towards materials – around one-third of the final cost will go towards materials.


    • Smaller renovations can end up more expensive per square metre than larger renos as many overhead costs are at a fixed cost e.g. getting a DA from your council.
    • Fees, levies, permits, taxes and GST accounts for around 20% of the overall cost of the reno.
    • If you’re planning to put your house on the market after the renovation, going overboard with expensive fittings such as high end taps, door handles and tiles can end up doing more harm than good. It’s likely that potential buyers won’t necessarily have the same preferences as you and won’t be prepared to pay extra for it.

    Wrap up

The process of building and renovating is a complicated process that can prove difficult to comprehend fully.
