The Knock Down Rebuild Benefits

There are many benefits to a knock down rebuild, but you might be wondering how this option compares to moving house or even undergoing a major renovation. Here are just some of the reasons:

  • Stay in your current location where you and your family have built memories

  • No need to worry about new neighbours — keep your current ones

  • Keep your kids at the same school with their friends

  • Save money per square metre compared to a renovation

  • No real estate or stamp duty fees

  • Go green and create a more eco-friendly home with better solar and insulation

  • Increase the value of your asset and your land

Knock Down Rebuild Costs

A common concern when renovating is the unknown costs that may arise throughout the project. Quite often, renovations end up costing twice as much as what was first anticipated as new problems are uncovered when the project begins.

If you choose to knock down and rebuild with an experienced builder like Montgomery Homes, we'll conduct an in-depth site analysis prior to any down payments, to determine the costs to knock down and rebuild a brand new home.

On average, a Knock Down Rebuild costs two to three times less than a major renovation. And the benefit of knocking down and starting again is you get to customise everything you've always wanted — from better insulation, a bigger kitchen, to that extra bathroom.

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. Clients who have completed a knock down and rebuild with Montgomery Homes have said it was the best decision they have made financially.
