How Much Will it Cost to Renovate or Extend my Home?

How Much Will it Cost to Renovate or Extend my Home?

One of the most common questions we are asked, is how much will it cost to renovate or extend my home. It’s nearly an impossible question to answer without all the variable factors considered in to the equation. It is a really important question though, and often the first one requiring some kind of answer before the real possibility is considered. Today I would like to share with you a few post I have found on the web, that give you an idea, or a base to start from when pondering this question.

For anyone considering raising their home and building in underneath, this post has a great pie chart to explain the percentages of costs involved. Once you have the pie chart, it could most certainly be applied time and time again, to help you find an approximate price to work on.

This post has a calculator that can be used, along with practical advice on how other factors contribute to the cost of your job, site location and condition, quality of finishes, and building complexity.


For an idea on the costs of extensions, have a look at this post to give you an overview of costs involved. If you’re at the beginning of your process, this may be the most suitable of all the pages to view.

Finally for a more complex guide again with a pie chart, SEQ Building Design have this guide to cost breakdown for an extension.

Good builders are always happy to provide quotes at any stage of your process, for some more advice on getting prepared to contact a builder read this Nuts & Bolts post with our builder Adam. Estimators are also available to assist in the costing of your job, and some architects will provide estimates as well.

Are you planning to extend or renovate your home? Have you used a calculator or estimator before?
