Stay close to your work, schools, neighbours, and local lifestyle with a knock down rebuild in Sydney

Demolition needs to be arranged by the owner and this process can take up to four weeks to complete. While demolition takes place, Montgomery Homes will obtain the construction certificate for your new home and prepare the final documents for your new home build. Make sure to find a licensed and insured demolition contractor to facilitate the demolition of your current house and to remove all the relevant materials, debris, trees, and roots. If required, we can suggest demolition companies in Newcastle, Hunter, Central Coast, and Sydney regions.

There’s a lot involved in preparing the site for a new home build. Therefore, it’s important to consult a new home builder before demolition commences. Once you have researched and engaged a demolition company to knock down your house, there are several items required to get the site ready, such as the removal of building materials, trees and roots, existing pools, and capping off the sewer. For more information, ask us about our knock down rebuilt fact sheet. We’ll guide you through the whole process.

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.

Site costs will vary from property to property. It all starts with a free site inspection — our team will complete a thorough review of the site and determine how much excavation will be required, whether there are trees and rocks on-site that need to be removed, whether there are any buried challenges we need to consider, and more. After completing the site inspection, we will provide an itemised list of site costs, all of which will be rolled into one tender.

Progress payments are staged payments made at key points during your build. Your lender will usually release each payment once the relevant construction stage is complete and any required checks have been carried out. This helps align your finances with the building timeline and gives you a clearer view of when payments are due.

Building approval timeframes can change based on: 

• Whether your project qualifies for CDC or needs a DA

• Your local Sydney council requirements

• Site slope, access, drainage and stormwater needs

• Heritage, flood, bushfire or easement restrictions

• Neighbouring properties and setback requirements

• Whether demolition approval is lodged separately

• How quickly required reports and documents are provided

Our team will keep you informed throughout the entire process, so you’re never unsure about the progress of your project.

While some builders limit you to certain home designs and parameters, Montgomery Homes provides you with the freedom to build the kind of home that specifically caters to the way your family lives. We provide a broad range of customisable, architecturally-designed home designs to suit your block no matter its size, angle, or location.

Absolutely. In fact, a brand new home in an established suburb should have a higher rate of appreciation and will be an attractive prospect for potential buyers or renters if you ever choose to sell or rent it out.

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. Ask us about putting you in touch with recent knock down rebuild clients to hear their experience firsthand.

Many homeowners use a construction loan for a knock down rebuild. This type of loan usually releases funds in stages as your new home is built, rather than as one upfront payment. It’s best to speak with your lender or broker early so you understand your borrowing capacity, deposit requirements, approval timing and how your loan will work once demolition and construction begin.

It depends on your lender, loan structure and building contract. Some demolition, service disconnection and site preparation costs may need to be paid before construction loan drawdowns begin. Confirm this early with your preferred demolition company and lender or broker so you can plan your budget and avoid delays between demolition and the start of your new home build.

Many Sydney blocks are suitable for a knock down rebuild, but every site needs to be assessed before you commit. The size, shape, slope, access and planning controls on your land can all affect what can be built.

Your block may be suitable if:

• The existing home can be safely demolished

• The block has enough width and depth for your preferred home design

• The site allows safe access for demolition and construction

• The slope can be managed with the right home design

• Stormwater, sewer and service connections can be planned properly

• Trees, pools, retaining walls or old structures can be assessed

• Easements, setbacks and council requirements have been checked

• The block suits your budget, lifestyle and long-term plans

A site inspection is the best place to start. Montgomery Homes can assess your Sydney block and help you understand which home designs may suit your land.

A knock down rebuild in Sydney will usually need approval through either a Development Application (DA) or a Complying Development Certificate (CDC).

• A DA is assessed by your local council. This pathway is often needed when your new home requires a more detailed planning review, or when the design does not meet CDC requirements.

• A CDC is a faster approval pathway for straightforward projects that meet set NSW planning standards. It combines planning and construction approval and can be assessed by the council or an accredited certifier.

As a guide, CDC approvals can be issued in as little as 20 days when all requirements are met. DA timeframes can vary depending on your council, site conditions, design complexity and whether extra information is requested.

Montgomery Homes will take care of the approval process for your new home. All you need to do is confirm how demolition approval will be handled, as it may require a separate approval or be included as part of the broader application.

We offer our knock down rebuild services throughout Sydney, from the Northern Beaches to the CBD and even as far west as the Blue Mountains and south to Wollongong and the Illawarra. We also offer services in Newcastle, the Hunter Valley, and the Central Coast!

The right home design will depend on the size and slope of the land. For example, if you have a narrow block, our team will recommend designs from our narrow home design collection. Likewise, if land has a challenging slope, we might recommend a split-level home design to make the most of the land. We’ll help you choose the right home design for the unique challenges of your property. You can choose the facade theme, the internal and external colours, and more! We’ll be with you through the entire process, so you can rest assured knowing you’ll receive the brand new home you’ve been dreaming of.
