How To Estimate Just How Much Your Home Extension Will Cost

Home extensions are a great choice if you are looking to change your house up without spending a fortune relocating and hopefully getting as comfortable there as you are in your current place. The main question on everyone's lips when considering a home extension is just how much it is going to cost. This is a fair question, as this will be a significant investment, but there is no one-size-fits-all answer to help you out. However, there are some considerations that you can think about that can give you a rough estimate for whether your home extension will be on the pricier side of things or budget-friendly.


If you live in quite a built-up area and have quite tightly packed neighbours, then bringing in a lot of construction equipment and making sure you are careful with subterranean pipes and wires will add to your price tag a little. It is always more difficult to build when space is a factor, but this is frankly unavoidable for many Australian's, as millions upon millions live in cities. Just make sure to budget a bit extra if you are in the more unfortunate circumstance of building in a compact suburb with poor street access.

Type Of Room

Adding a simple garage to most homes is a very simple task that requires little planning and very few tradesmen as well. On the other hand, an entire new kitchen or state-of-the-art man cave with all the bells and whistles is going to run you back a bit more. Think about the style and design of the room you want. The more polished and finished it is, the more expensive your home extensions will be. That is why it is vital that you get all your extension needs done at once so that you can bundle this cost and not waste resources.

Grading And Foundation

If the land you are going to extend your home out onto is not similar to the gradient your current house takes up, then flattening it out will cost a fair chunk of change. Making sure everything is even and has the same foundation system is key to making sure your new home extensions aren't lopsided or age prematurely. Landscaping and changing the garden to fit your new extension will also run you up a bit more, but that can be left to a later date if you wish to save a little more in between.
