Upfront Checklist

When assessing your block of land for a Knockdown & Rebuild you need to first consider the following:

Planning Regulations

Street frontage & depth of block



Slope of your block of land

Orientation & natural light

Driveway position


Street Access

Power Supply




Planning Regulations

The first step you should take is to contact your local council to determine if there are any overlays (such as heritage or vegetation) affecting your land. Alternatively, you can access this information online at addresssearch. Enter your address and click search. The following screen will display your address; select the box and search again. You will then see various reports available. We suggest selecting the basic property report by ticking the corresponding box and clicking next. This summary page will show your Planning Zone and Planning Overlays that affect your land. You should review these reports or reach out to your local council for further clarification.

Street frontage & depth of block

When selecting a new home plan, the size of your block is crucial. Typically in established areas, the Council mandates that the setback of the main frontage of your home align with the average setbacks of both neighboring properties. If you prefer your home to be positioned further forward, you will need to obtain a Report and Consent approval through the Council. This process can begin after your tender appointment is complete, with the assessment period usually taking about six weeks.


All new dwellings must comply with building regulations, which include meeting minimum front, side, and rear setback requirements. Make sure to discuss these requirements with your Sales Consultant when planning your new home.


Do you have any easements on your block of land? Easements can influence which designs are suitable for your block. You can obtain this information by contacting the easement holders (such as the council or water authorities) or from your Plan of Subdivision.

Slope of your block of land

What is the slope of your block? Does it slope from front to back, or side to side?

Understanding the gradient of the block and the proposed driveway is essential to determine its suitability for construction. Senka Homes will organize an initial site assessment through your Sales Consultant. This assessment will be conducted by a specialist trained assessor to decide if the site is suitable for construction. 13

Upfront Checklist continued

Orientation & natural light

It's important to carefully consider where your new house will be positioned on your block. Ideally, the orientation of your new home should be planned to maximize the amount of natural light it receives.

Street access

You need to consider the accessibility of your block for both demolition and construction.

Factors such as the size of roads, nearby schools, overhead power lines, and the need for traffic management (especially if you are on a busy road or in a hard-to-reach area) must be taken into account. Be aware that blocks with restricted access may incur additional charges due to traffic management and the manual unloading of materials.

Driveway position

When choosing a house plan, make sure to consider the position of your existing driveway. If you decide to change the location of your crossover (driveway), you will need to obtain approval directly from your Council.


We advise assessing the adequacy of the Legal Point of Discharge (LPOD) prior to the commencement of working drawings or the application for a permit. All sites must have a legal point of discharge (LPOD) and a sewer tie within the property boundary for drainage before construction begins. In some established areas, your existing LPOD might not be adequate for a new dwelling. If the LPOD is not within the boundary, it is the client's responsibility to ensure it is relocated inside. Any extra costs incurred are the owner’s responsibility. The Council will identify the satisfactory LPOD, and Senka Homes will arrange for this information to be obtained prior to your tender appointment and presented at that time. Additional construction needs will be assessed during this appointment.


Power supply

Senka Homes constructs all new dwellings with underground power. If your existing dwelling has overhead power, it will need to be abolished before demolition, and you will need to arrange for the installation of an underground electricity pit through your provider. This process can start before demolishing your home and might take some time. You can contact your provider for an application form, and Senka Homes can assist you in completing it if necessary. After submitting the form, you will receive a quote valid for 30 days. Once you have paid within this period, the installation of your electricity pit will take about 28 days. Following installation, it can take up to 21 days for your electricity pit to be energised. Senka Homes requires a live electricity pit before construction can begin.


Gaining your neighbors' consent upfront can play a crucial role in the approval of your design. If your proposed build does not comply with standard building regulations, securing early agreement from neighbors is essential, as any objections they raise could impact various aspects of your home's design, such as ceiling heights and window placements, potentially delaying construction. Additionally, it's important to engage with neighbors about fencing issues, as fences may need to be removed before construction begins, depending on your build.


Are you planning to install a new pool or keep the existing one? It's important to discuss this with Senka Homes upfront as it influences the choice of your house plan and can affect the cost of your slab design and overall construction. For safety and compliance, Senka Homes requires a minimum distance of 1800mm between your home and the pool. Additionally, you'll need to install a hard pool cover that meets Australian Standards before construction starts. Please ensure to cover this topic in more detail during your tender appointment. 15

YouryourJourney, blank canvas.

Only you can answer this, or maybe you're still uncertain?

We are here to help.

We hold the view that your home is the ultimate expression of yourself, as everyone is unique. Your personal style might be reflected in the color of your walls or your choice of carpet, or it may embody what matters most to your heritage, family, culture, or even the places you've visited and captured in photographs, or the treasures you've amassed on your travels. 18

Every journey is distinct and mirrors a bit of who you are.

On your style journey, we'll assist you in choosing from four overarching themes: Traditional, Retreat, Modern, and Couture. Within each of these themes, there are nine styles to give you a quick snapshot of what resonates with you.


This style is crafted for those who value a classically inspired aesthetic. It features a harmonious balance of texture, colour, and pattern, combined with timeless furniture and antiques. This style enables you to collect pieces that endure through trends and time, perfect for a Traditional theme.


Sleek lines and understated colour schemes allow the architectural design to stand out in your home. Chrome accents and vibrant artwork blend seamlessly with fabrics and dark woods, creating a stylish sensory experience that remains warm and inviting, ideal for the Modern theme.


What's trending? What's current? The Couture theme captures the elusive and sophisticated flair of the innovative and artistic. The concepts, ideas, and styles showcased in the Couture portfolio are drawn directly from the runways and design capitals of the world, embodying cutting-edge fashion.

Envision the ideal holiday escape and you'll find yourself in the Retreat theme. This theme draws its inspiration directly from some of the world's most enchanting resorts, featuring a delightful mix of textured and patterned fabrics coupled with exquisite furniture pieces.

Key things you need to know

Now that you've selected the perfect home for your existing block, we'll guide you through some important details you need to know and clarify which aspects fall under your responsibility.

Site Assessment Temporary Fencing

Senka Homes will visit your block of land to conduct a comprehensive site assessment, addressing the following:

Site accessibility. This includes access for construction from all four boundary sides.

Fall across block.

Overhead power lines will need to be evaluated for site access.

Neighbouring properties and the orientation of the proposed new dwelling.

Re uirements for traffic management.

Location of trees.

Establish any OH&S onsite re uirements.

Possible driveway locations.

Council compliance review.

Your demolition contractor will arrange for temporary fencing during the demolition phase. This temporary fencing will need to be removed before Senka Homes begins construction.

Senka Homes will provide temporary fencing during the construction of your new home.

Established Fencing

Existing side and back fencing will need to be assessed and may need to be removed for access reasons; please consult with your neighbours. Front fences will be demolished along with the house, including the footings. Details about your specific fencing requirements will be provided during your tender appointment with Senka Homes.

Please note that it will be your responsibility to remove existing fencing if required by Senka Homes.


Asset Protection Permit for Demolition

You will need to secure an Asset Protection Permit from the Council before starting your demolition. This involves paying an application fee and a bond that covers any potential damage to existing council infrastructure, including footpaths, nature strips, and driveway crossovers.

Demolition Permit

Your demolition contractor will need to apply for a Demolition Permit from your local Council. Once an application is submitted, it can take up to 28 days to be issued.

If your existing dwelling or the overall site contains asbestos, your demolition contractor will be required to remove it and provide you with a certificate proving the asbestos has been removed.

You will need to provide Senka Homes with a copy of your demolition permit before construction can commence.

Tree Removal

Is there a vegetation overlay? Permits may be required to remove any trees that are in the area. At your tender appointment Senka Homes will provide you with a demolition plan nominating which existing structures need to be removed, including any trees.

If a permit is required to remove any trees, you will need to arrange an application with Council for their removal. In some cases, Council may require an Arborist Report, which they can arrange on your behalf or alternatively you can arrange for your own arborist and supply their report with your application. Generally speaking, if you have a Vegetation Protection Overlay, a permit will be required to remove a tree that is over and above 10 metres with a diameter of 0.5 metres at a nominated distance of L5 metres from ground level.


Check with council if there is a local law in place protecting any trees. This may be the case even though no overlay is identified on your block.

Water Meter

Disconnection of Services

Before any demolition can commence, you need to ensure all existing services are disconnected.

Contact your utility supplier to have the gas disconnected and capped.

Contact your utility supplier to arrange for the electricity to be disconnected and removed back to the feeder pole. Note that power disconnection can be a lengthy process, so to avoid delays, it s advisable to organise this early in your planning.

Contact a registered plumber to remove the sewer back to the tie locations and cap. Some demolition contractors will include this in their scope of works. Note:

Contact a registered plumber to remove all stormwater drains back to the legal point of discharge, or to the title boundary if they are outside the property.

As a general note, ensure that you cut back and cap all services as close to the boundary as possible. This approach helps avoid additional charges from the builder for excavating any remaining services around the original house location.

Make sure your tradespeople install location markers for any services that have been capped off. This will eliminate the need for the builder to conduct a location survey later.

These components can be easily damaged during the demolition process and are costly to replace. We strongly advise that you speak with your demolition contractor and request that they take necessary measures to ensure the protection of your meter during demolition. Demolition should only commence once Senka Homes has applied for your building permit. This application will be made on the day you sign your contract. Approximately 3 to 5 days after signing, you will receive a checklist detailing the items that need to be completed or provided before obtaining your building permit. Your Building Coordinator will contact you once this has been received and assessed to confirm that demolition can begin.

Don’t demolish yet! 21

Demolition Process

It's important to hire a registered demolition contractor as soon as you can.

Senka Homes can assist you in this process by recommending reputable and qualified demolition experts. Please consult with your Building Coordinator.

Remember to obtain 2-3 quotes, as pricing and inclusions can vary significantly. Some contractors might include service disconnections, tree removal, and asbestos removal in their scope of works, while others may offer only demolition services.

Pre-Construction Consideration

Once you have arranged for the demolition of the existing dwelling, it's important to prepare the site for construction. Here are some key points to consider:

Clean & clear site

Senka Homes will require your site to be clean and clear following the completion of your demolition. You must ensure that your demolition company removes all debris from your block. It's common for materials like bricks or timber to be left just below the surface, which can be exposed when Senka Homes begins the first phase of construction. If debris or additional spoil is found, Senka Homes may need to charge extra costs to remove any excess debris left by your demolition company. Please inspect your site once demolition is completed and provide your Building Coordinator with a photo confirming that your block is ready for construction.

Hazardous materials

Asbestos is commonly found in established homes. Your demolition company is responsible for removing this material, and you need to ensure they eliminate all traces of it from your block. Should Senka Homes discover any remnants of asbestos during the pre-construction inspection, we will not be able to commence work (for safety reasons) until all the asbestos has been completely cleared.

Protection of neighbour's property

A Protection Works Notice can be arranged for you by Senka Homes. This may be necessary to insure against any issues that could affect your neighbors during construction, especially if Senka Homes is building close to your boundary. This notice would need to be signed off by your neighbors and could also apply to structures like your garage or any retaining walls. 23
