Have you outgrown your home and looking to upgrade with more space for your family? One of the most requested home design options is a four-bedroom floorplan with a two-car garage and two bathrooms. Before embarking on your home building research journey, you’re most likely asking the question, ‘how much is it to build a 4-bedroom house in NSW’?. In this Blog, we uncover the cost to build a 4 bedroom house, plus how you can save time and money with one of our three inclusions packages: Advantage, Sapphire, and Diamond Collections.

Cost per sqm to build a 4-bedroom house

There are a number of factors that contribute to the overall average cost to build a 4-bedroom house (per square metre). Plus, every family is unique and will want a home design that reflects their family’s’ wants and needs. Prices can vary drastically with contributing factors such as turnkey items, slope of the block and level of inclusions all impacting the price of your four-bedroom home. Using our Avalon 209 home design as a base, the cost per sqm varies from $1601 to $1862 depending on which Collection and facade you select.
