How Much Does it Cost to Build a 4 Bedroom Home in Sydney


Growing families eventually need more room to spread out. When it’s finally time to ditch the 3-bedroom domicile, you are probably going to start asking yourself “How much does it cost to build a 4-bedroom home in Sydney?

You will get different prices depending on who you talk to, but in general, builders and architects calculate costs on square footage, rather than the number of rooms.

The average cost of building a home in Sydney

If you were to look at figures from the Australian Bureau of Statistics, square footage prices averaged out at $1270.80 per sqm in June 2018. Bear in mind, this number does not take design into account, or the cost of permits, and site work.


Site works and house design


Site work refers to the preparation of the land before building such as soil testing, land clearing, levelling and grading, and installing retaining walls where necessary. Extensive site works can significantly increase the cost of your build.

In most situations, site works will be out of pocket expenses you will need to take care of before pouring the slab. A slab can cost up to $120 per sqm. A site which has difficult access or needs a thicker slab will push the price closer to the top end.

Off the plan, 4-bedroom homes will usually be significantly cheaper than a custom design because you are limited in customisation options and aren’t paying for an architect to create a custom solution.

Other factors influencing the cost of a 4-bedroom house in Sydney will be the design considerations. Finishes and fixtures you choose will either raise or lower the price as will the material you put down for the floor.

As you can see, there are a lot of things to consider when working out the cost of a home, but there are ways you can remove most of the mystery from the equation.


Advantages of a professional building cost estimator


When you’ve decided it’s time to upgrade your living arrangements, dealing directly with architects and builders can be intimidating. Your goal is to save as much as you can on the cost of building your new home. Without experience in the industry, you only have the word of your builder and architect to go on.

A building cost estimator is a professional who can provide peace of mind by creating detailed cost estimations about how much your project should cost.
