The Knock Down Rebuild Process

Before we embark on your Knock Down Rebuild journey, it’s important for us to conduct an all-important free site appraisal. This analysis will help us determine which of our home designs are best suited to your block based on the characteristics of your allotment and any neighboring allotments. Once your free site appraisal is complete, your appointed new homes consultant will provide information on our home designs, competitive pricing, premium inclusions and the available upgrade options.

Detailed information about your site is obtained to ensure we understand the requirements of your project. This involves obtaining reports such as a feature survey, soil report, arborists report (if applicable) and property information report. These reports help us estimate accurate site cost allowances to reduce the risk of unexpected costs down the track. A formal quote and siting plan are issued so you know where you’re placed financially and can see exactly how your new home will be positioned on your block. 

Working with your new homes consultant, you have the opportunity to tailor our floor plans, make structural changes and add extras to ensure the design is perfect for your family and how you live. Once your changes have been finalised, your sales estimate is updated and a full set of drawings including internal elevations of your kitchen, bathroom and laundry is issued in preparation for your design review appointment.

You’re invited to attend an electrical and design review appointment, in which you will discuss electrical upgrades such as additional downlights and power points, as well as any changes you want to make to the internal appearance of your homes, such as joinery configurations and built in cabinetry. Once your changes have been finalised, your sales estimate and drawings are updated in preparation for your colour appointment. You will now return to our colour studio to select your select your external and internal colours, finishes, fixtures and fittings. For many, this is one of the most exciting steps in the Knock Down Rebuild journey.

Final pricing and issued and your contract is prepared. You attend a contract signing appointment to sign your contract. You’re introduced to your project coordinator, who will be your dedicated assistant from now right up until you receive the keys to your new home. Your project coordinator prepares and submits your building permit application and will liaise with the building surveyor to source any additional information or documentation they require.

If you have an existing home on your site, now’s the time to arrange demolition. Once the site is clear, a re-establishment survey is ordered, enabling us to complete the final items required for your building permit. Your building permit is received and construction begins. You’re introduced to your site supervisor who, alongside your project coordinator, will provide regular progress updates throughout construction. Before you know it, you’re holding the keys to your brand new dream home!

Commonly referred to as KDR, Knock Down Rebuild involves exactly that; knocking down (demolishing) an existing home and building a new home on the now vacant lot.

We offer a no obligation, free site appraisal. This analysis helps us determine which of our home designs are best suited to your block, assess any conditions that may apply to your block, and advise on the project’s overall feasibility.

We have a range of single and double storey home designs to suit blocks of different sizes and dimensions. By taking advantage of our free site appraisal, your new homes consultant can provide you with a good indication of which of our homes are best suited to your block.

You may or may not require a TownPlanning permit, and the best way for us to determine this is by conducting a free site appraisal. A TownPlaning permit may be required for things like vegetation removal, building close to a boundary or simply for the style of home you want to build. If a TownPlanning permit is required, we will submit the application and manage the approvals process on your behalf.

Whilst Sienna Homes can guide you through this process, we are not a demolition company and therefore cannot demolish your existing home ourselves. We can provide you with a list of reputable demolition companies that have been used and recommended by other clients and achieved optimal results. You will then be required to contact one of these companies and arrange demolition with them directly. 

Yes, you will require a demolition permit. This is generally arranged by your chosen demolition company.

Construction timeframes vary depending on house type. On average, you can expect construction to take anywhere from 9-12 months.

Demolition costs vary between contractors and not all contractors are created equal. It’s important to choose an experienced demolition contractor that can get the job done efficiently and effectively. Factors such as accessibility, house size, house type and hazardous materials can have a big impact on demolition costs. In our experience, demolition costs can range from $12,000 to $40,000.

In order to provide accurate initial pricing, we must first conduct a no obligation, free site appraisal. This analysis helps us determine which of our home designs are best suited to your block, assess any conditions that may apply to your block, and advise on the project’s overall feasibility. Every block is different and factors like lot size, orientation and soil conditions can have a big impact on overall costs. Allowing us to assess your individual block means we can factor in these costs from the beginning, and ultimately provide you with a better indication of overall costs early on.

A soil test is conducted by a Geotechnical Engineer who drills into the soil to determine its reactivity at various depths. It is important for us to understand how stable the soil on your block is as this will determine the kind of footings your new home will need. It is vitally important that your home is built on an appropriate foundation. If your soil is subject to a high level of movement, or ‘reactive’, your home will require stabilising footings. Moisture is the main cause of movement, so sandy rocky soil is usually more stable than clay.

An arborists report is a comprehensive evaluation of any trees on your block. It’s used to identify the condition, health and safety of the tree/s, and ultimately provides a risk rating which helps to determine if upgraded footings are required or if any precautions need to be taken during removal of the tree or construction around it.

A feature survey is obtained via a site inspection and used to gather information on where your new home is best positioned on your block and if there are any obstructions such as trees or vegetation that need to be addressed prior to construction.
