Why choose a knock down rebuild in the Illawarra?
A knock down rebuild is an ideal choice for those who love their location but need a home that better suits their needs. Here's why it's a smart choice:
Stay in the location you love
Avoid the hassle of moving by rebuilding on the land you already own. A knockdown rebuild lets you stay close to schools, work, and community connections while upgrading to a modern, functional home.
Start fresh with a blank canvas
Unlike renovating, which can be limited by your existing structure, a knock down and rebuild offers a blank canvas for your dream home. You can create a new home that perfectly aligns with your family's lifestyle.
Avoid the hidden costs of moving
Moving house often involves stamp duty, agent fees, and other unexpected expenses. A knock down rebuild eliminates these costs, helping you save money while investing in a home that meets your needs now and into the future.

Whether you need more bedrooms, open-plan living spaces, or a private retreat, a knockdown rebuild lets you build a home that grows with your family.

At Montgomery Homes we understand that building a new home is an exciting life milestone, and we build every home as if it were our own — ensuring quality from the inside out. The timeframe for building a new home varies according to a number of factors including, but not limited to— the home design selected (single-storey vs double-storey or split-level), the individual specifications of the block of land (including site accessibility and condition), and external approvals (such as local council and BASIX). Behind every Montgomery Homes build is a team who are passionate about seeing your dream home come to life. Please get in touch with our team to enquire about the build timeline for your new home.
Most Australian homeowners strive to increase the value of their largest asset and gain more equity in their home. In recent years, land prices have increased considerably and made it more attractive to stay put and enhance the home in your existing location than find purchase another home or new block of land. If your home is aging and you are looking to increase its value, there are two options: you can either undertake an extensive renovation or knock down and rebuild on your existing site. If you’re considering making structural changes to an existing property, costs can vary considerably. A major renovation can end up costing more than double per square metre when compared to a knock down rebuild. Renovations run the risk of over-capitalising and going over your budget. If you choose a knock down and rebuild project with Montgomery Homes, on the other hand, you will be given a detailed and transparent price at the very beginning to avoid unpleasant costs and surprises along the way. This means you can spend less time wondering how much everything is going to cost and more time daydreaming about the fun stuff like colours and home decor. Some people get frustrated searching for a home in a good neighbourhood. It can be stressful trying to find a home for the right price and sometimes it makes more sense to keep your current neighbours and rebuild on your site. Consider the resale value and what’s going to get you more bang for your buck.
On average, a major renovation is more than double the cost of a knock down rebuild per square metre. The cost to have your house demolished can differ depending on the size of the house, volume of material, if asbestos needs to be removed, and if there are any established trees or pools on the property. On average, the cost to demolish your house can range between $20,000 - $30,000. The knock down rebuild cost for your new home will vary depending on the type of home you build, the size of your home, whether it’s a split level home, and any additional upgrades you choose. At Montgomery Homes, we provide a free tender quote so you will know all knock down rebuild costs upfront before making a decision.
