How can I obtain a quote?

To start the process of obtaining a quote from us we ask that you fill in your information on the contact us page. Once your contact information has been entered it will take you through to our questionnaire. Here, we ask you for a basic outline of your enquiry to see if we are able to assist you. This will ask you about the number and type of rooms you are looking to add to your home, the basic type of materials you would like to use such as roofing and flooring. We will also ask whether you have plans, what your budget is and your timeframes for the build. – If you already have plans and/or DA/CC/CDC approval, please attach them to the questionnaire along with any additional surveys, engineering plans, reports that you may have. Once we have received your details, the builder will review the information and we will contact you for further details or to schedule an appointment for him to meet with you ahead of providing you with a detailed quote.

I don’t know what my budget is, why do I have to provide one?

Don’t overthink this! We don’t expect you to know how much the build will cost. However, as the home owner you will have an idea of how much you have/can borrow to complete the works. We need to know this so that we can advise you if this amount is realistic. We don’t want to waste your time and we will be honest and upfront with you right from the start.

I have plans, can you build based on these plans?

Through our extensive experience building additions and extensions, we have found that when we are presented with plans provided by an external provider, these often do not take into consideration the real cost of building. To address this challenge we make sure that we look after the entire process from start to finish. We will work with you to create plans that will align with your quote. If you have had plans prepared in advance, we ask you to set these aside and work with us and our draftsperson to ensure that we can tailor your addition utilising the most cost-effective design that takes into consideration all the intricacies and requirements of building an addition or extension. Through our extensive experience in building additions and extensions, we know what can work, what is achievable in line with build cost expectations and what to avoid when designing an addition or extension. This experience ensures that we know what is the best way to utilise the funds you have available to achieve the best outcome for you and your family.

The Home Extension Process In NSW: Step-By-Step Guide

If you’re planning to add more space to your home, one of the first questions you’ll likely ask is: What is the process for a home extension in NSW?

While every project is different, most home extensions follow a similar path, from the initial consultation through to approvals, construction and handover. Understanding each stage helps you plan ahead and avoid surprises along the way.

House extension, where to start?

The best first step is to define what you want the extension to achieve.

You may need additional bedrooms, more living space, a larger kitchen or better functionality for a growing family. Once you have a clear goal, an extension specialist can assess your property and help determine what’s achievable based on your home, block and budget.

Projects involving significant structural changes often benefit from early planning and specialist advice, particularly when they form part of broader, large-scale renovations.

Step 1: Consultation and site assessment

The process begins with an initial consultation to discuss your ideas, budget and objectives. This stage allows your builder to assess the existing home, identify potential opportunities and flag any site-specific constraints that may influence the design or approval process.

Step 2: Survey, concept plans and design development

Once the project moves forward, the design phase begins.

A surveyor will conduct a detailed survey of your property to capture site information required for planning and design. From there, the drafting team will meet with you, undertake a site measure and prepare concept plans that reflect your goals for the space.

As the plans evolve, they are reviewed against the project budget to ensure the design remains aligned with your build cost estimate.

Step 3: Engineering and approval preparation

Before plans can be lodged for approval, they need to be supported by the appropriate technical documentation. Your builder will work closely with structural engineers to ensure every element of the proposed extension is practical, compliant and structurally sound.

Step 4: DA or CDC lodgement

One of the most important stages in the home extension process is obtaining approval to build.

Depending on the project, this may involve either:

Complying Development Certificate (CDC)

A CDC may be available for projects that satisfy specific planning controls and development standards.

Development Application (DA)

Where a project does not meet CDC requirements, a Development Application is typically submitted to the council for assessment.

At 32 Degrees Building, we prepare and lodge the required CDC or DA documentation on behalf of our clients, helping streamline the approval process so you are not navigating the paperwork alone.

Step 5: Contract signing and project planning

Once approvals are progressing and construction documentation is finalised, the building contract is issued.

This includes signing the HIA Fixed Price Residential Building Contract and confirming the project scope, inclusions and timeline.

You’ll also be introduced to your project manager, who will meet with you onsite to discuss the construction schedule, answer questions and ensure everyone is aligned before work begins.

Step 6: Construction

With approvals in place and contracts finalised, construction can begin.

Depending on the scope of works, this may include demolition, structural alterations, framing, roofing, services installation, internal fit-out and finishing works.

For extensions and renovations, the new works need to integrate seamlessly with the existing home in terms of structure, functionality and appearance.

Step 7: Completion and handover

As construction wraps up, final inspections are completed and any remaining items are addressed.

Once the project reaches practical completion, you’ll receive the relevant documentation and be walked through your newly completed space.

Start with the right team

At 32 Degrees Building, extensions, additions and major home renovations are the core of every project we take on. That means we understand what working with an existing home actually involves: structural considerations, the approval processes and planning that makes the difference between a new space that feels right, and one that feels tacked on.
