Have you outgrown your current home and are looking to upgrade with more space for your family? At Montgomery Homes, one of our most requested home designs is a 4-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’ll share the cost to build a 4-bedroom house as well as how you can enhance your home design with one of our three inclusion packages: Advantage, Sapphire, and Diamond Collections.

Cost to build a 4-bedroom house in NSW per square metre

There are a number of factors that contribute to the average cost to build a 4-bedroom house (per square metre). Every family is unique and will want a home design that suits their wants and needs. Prices can vary drastically based on turnkey items (aka everything you need to move straight into your new home), the slope of the block and your choice of inclusions package all impacting the price of your 4-bedroom house

Using our Avalon 209 home design as a base, we’ve calculated the cost to build a 4-bedroom house in NSW per square metre. According to the Montgomery Homes price list for 2021, the cost per sqm varies from $1305 to $1578 depending on the facade you choose.

What is included in the Advantage Collection?

The beauty of the Advantage Collection is that your new Montgomery Home will have all the essential turnkey items, quality fittings and joinery needed for a fast-tracked move-in schedule. 

The kitchen is where you will entertain friends and host family dinners — it truly is the heart of the home. With a ceramic tile splashback, 20mm stone benchtops and an Artusi stainless steel kitchen appliance package (including oven, cooktop and rangehood), you’ll be inspired to take your host/hostess skills to the next level.  

Quality tapware and cabinetry will feature across your new home as well as stunning chrome-framed mirrors over your vanities. Plus, you will have the opportunity to create a relaxed, contemporary atmosphere with a consultation with Your Home Consulting, the experts in lighting for your home. 

The outside of your home can be just as important as the inside — the Advantage Collection allows you to enhance your exterior design with external finishes including a Colorbond automatic panelift garage door and concrete roof tiles. As for those essential turnkey items, think a single folding frame clothesline, an alfresco roof and slab, driveway, digital TV antenna, prefabricated freestanding letterbox and more.
