Knockdown Rebuild

Inspiration exists at your address – with a knockdown rebuild option!

Keep your address and embrace all the convenience and appeal of modern, open plan living with a brand new house.

A knockdown rebuild project at Henley will step you through the planning and application process, as well as demolition and of course, rebuilding.

Start fresh
Head to our brand new Glen Waverley display centre and speak to our specialist knockdown rebuild consultant Jane Todd, who has 20+ years of industry experience. She’ll step you through the paperwork, permits and approvals, so you can relax and enjoy your brand new, modern, fully-integrated, energy efficient home.

No compromise
What’s old will be brand new again, without any compromise:

  • We have over 80 home designs to choose from, so you can handpick the perfect design for your lifestyle and land
  • You can enjoy ongoing savings with an energy efficient home design
  • Make the most of modern open plan features, ensuites bathroom, built in robes and integrated alfresco
  • All new fittings and fixtures, with doors that open and close as they should!

Save on fees
If your home was designed before open-plan living, rebuilding is a more affordable alternative to buying elsewhere, or renovating. It can allow you to save on:

  • Stamp duty
  • Real estate fees
  • Cost per metre, which can be much higher in renovations than it is when building a new home from scratch

  • Guarantees that withstand the test of time with our industry leading 50 year structural guarantee and product warranties

How to prepare for a knock down rebuild project

Your designated customer service administrator will be your main point of contact throughout the demolition phase, here's an overview of what needs to happen as well as a knockdown and rebuild demolition information sheet...

Step one: Research and preparation

  • Speak to your council about your intention to demolish your home and find out relevant details about your land.
  • Obtain an Asset Protection Permit from your council.
  • Find a demolition company.
  • Request a copy of your Demolition Permit from your demolition company and forward it to us.
  • Disconnect power and gas – your utility company will need time to process your request so organise this in advance.

Tell your demolition company to complete the following:

  • Cap sewer connection and remove line from house.
  • Cap water meter and tap and remove line from house (water tap and meter to remain on site).

More information is always welcome: When you speak to your council, try to find out as much information as you can as this will help you to foresee potential issues. In particular, try to determine when sewer lines were installed in your area – this can flag potential future issues such as hidden items in the earth, septic tanks, wells, pools, pipes, etc. If you pinpoint these issues prior to construction, you may avoid the extra cost of removal, and possible reengineering, of your slab design. Please note that council information, or lack of, is not necessarily a reflection of what may or may not be found on site and could impact on any planning overlays.


Step two: Onsite connections and considerations

Water Connections:

  • Do you currently have clay pipes on your land? If you are unsure, the date your property was established will allow you to determine its water tapping connection – any property established prior to 1989 will generally have clay pipes. An additional item will be included in your Tender if you currently have clay pipes. This is to cover the costs of converting your clay pipes to PVC connections.
  • Does your storm water discharge to the kerb? If yes, you may require a charged pump LPOD system. This will be determined by an engineer and is site specific.

 Power Connections:

  • Is your power connection currently overhead? If yes, you will need to arrange for an electricity pit to be installed by an electrical contractor to enable us to run underground power connections.
  • We recommend that you organise the installation of an underground pit as early as possible as it can be time consuming. A costly generator will be required if it is not installed prior to construction. To organise this, speak to the new connections department of your power company. They will send you a form that will need to be completed to show the amount payable and they will also request a copy of the site plan nominating a preferred location. You will need to let them know that you need an underground power pit installed and obtain the ‘Request for underground power’ form.
  • Amps – in most cases you will require less than 100 amps.
  • Single phase/three phase – If you plan to have refrigerated air conditioning in your home then you should have three phase installed otherwise single phase is sufficient. Please discuss your specific requirements with your power company.

Site Considerations

  • A leafy outlook is lovely, so if there are any trees you'd love to keep on your land, you'll need to let us know. If the house falls within the perimeter of the tree, you may need an arborist report and tree root barriers may need to be installed. Bear in mind, this could be expensive depending on the tree and its proximity to the new home.
  • If you're on the fence about your fence quality, it will probably need to be replaced, as you will only be permitted to retain your fencing if it is in good condition.
  • Is your garage on the boundary? If yes, it is your responsibility to organise for the removal and re-installation of any affected fences with your neighbours.


Any additional items will be included in your Tender for a reestablishment survey – This is required for all demolitions as it will indicate clear title boundaries. Henley will only build from title boundaries.

Step three: Post demolition

It's time to set your sights on onsite construction, so please ensure all excess soil and rubbish is cleared and grass has been cut.

Tell us when the demolition is complete and we’ll organise the 2nd soil and survey.
