Extensions can be complex. We've compiled and answered the most commonly asked questions we get from clients.
Once you call or email us with an enquiry about a home extension, one of our experienced Design Consultants will make an appointment to meet you at your home to discuss your requirements, design and budget.
Our Design Consultants are experienced in understanding the planning requirements and constraints unique to your property.
Following your consultation, a 3D Conceptual Design may be prepared showing your existing home and the proposed new extension. A detailed cost estimate will then be prepared and presented for your approval.
One of the many benefits of engaging an experienced builder like Supa Group to build your home extension is that we understand, on average, the length of time any project will take from start to finish.
There are three distinct phases that occur when you work with Supa Group- the Design phase, the contract preparation phase and the build phase.
We have an experienced team at our office who will look after all aspects of your project from the very beginning through to the conclusion and obtaining the Certificate of Final Inspection from the Building Surveyor.
This includes preparing your design; carrying out all preliminary works to get your project to the site including engineering, soil reports and energy assessments; obtaining a building permit; carrying out all aspects of the construction; as well as obtaining all relevant approvals including a certificate of final inspection.
Supa Group has a great team in the office as well as long-term and highly regarded relationships with external professional service providers and trades to ensure that you are fully looked after during the entire period of your dealings with the company.
No. Supa Group will design the extension and as part of this process your Design Consultant can incorporate any specific ideas that you may have into the design, so your input is encouraged. With our 3D Conceptual Design program plus the vast experience of our Design Consultants and qualified drafts people, we will design your home extension to your specific, individual needs, and budget.
The Design phase involves our clients working with our Design Consultants. A concept is prepared and presented to you for consideration. This may take a few revisions after feedback is received from you as to any suggested amendments. Our costing department will then prepare a detailed costing of the project that will determine the ultimate price of your extension. When an agreement is reached on the concept design and the cost, an initial Order of Engagement is prepared and a deposit is paid.
The Order of Engagement is an agreement that allows us to spend money on your behalf to progress your project to the next phase. Depending on how quickly an agreement is reached, this phase can take between six to twelve weeks.
Yes - you can see your designs live as part of our 3D design process. Using 3D software, you’ll get an immersive view of how your floor plan looks and feels. We can even make changes in real-time as you watch.
The Build phase involves the actual construction of your home, and depending on the complexity of the project typically takes between five and seven months.
All of Supa Group’s building contracts have a fixed price and fixed completion time which is written into the contract. The fixed completion time commences once the Building Permit is obtained.
This is entirely up to you. A number of our clients will choose to engage their own contractors for certain aspects of the job (i.e. an electrician or a plumber) and we will happily work in conjunction with our client’s trades as long as all relevant Occupational Health and Safety and insurance requirements are met by the trades in those circumstances.
Supa Group has all the trades necessary to complete your project. One of the many benefits of using Supa Group is that we have dedicated trades that assist us in building projects to a high standard within a given period of time.
If we are to use your trades they need to be available when required so the progress of your project is not jeopardised.
The main determinant of this is whether the client has access to bathroom and toileting facilities. Most of our clients chose to live in their homes during the entire construction process. A few chose to move out for a short period and a very small number will move out for the duration of the project.
When clients chose to remain in the home, our Building Department will work closely with them to schedule the building works to ensure access to bathrooms etc. at all relevant times. You will also be inducted to our Occupational Health and Safety requirements to ensure your safety on site during the construction process.
This has to be assessed depending on the individual circumstances and can be discussed with the building team.
Our website contains photographic examples of the various stages. The Construction stages represent a logical sequence that needs to occur in order to build your extension.
It includes the Initial Deposit, Demolition, Base Stage, Frame Stage, Fix Stage and Completion.
There may be slight alterations to these stages due to the type of project, for example, if your extension is a second-storey extension there may be separate stages for the lock-up and plaster.
Supa Group is a long-established member of the Housing Industry Association, and we use their standard Victorian Alterations, Additions and Renovations Contract.
Within that document, the terms of the agreement are formalised between Supa Group and the client.
This includes a description of the various stages throughout the build and the progress payments relating to those stages.
This phase involves taking the concept design to a point where the project is ready for construction. Supa Group uses the deposit that you have paid to arrange a soil test, get working drawings prepared, engineering, energy assessments etc. We use this information to confirm the quote and prepare the building contract.
If your project does not require town planning, this phase can take approximately six weeks.
If town planning is involved then the timing is in the hands of the relevant council and may take between four and six months depending on the planning constraints.
