Common Renovation Mistakes in Australia – and How to Avoid Them
Renovating your home is one of the biggest investments many Australians will ever make. Whether you’re adding a second storey to create more space for your growing family or transforming your existing layout, a well-planned renovation can significantly increase both comfort and property value.
At 32 Degrees Building, we specialise in second-storey additions, ground-floor extensions, and large-scale renovations across Sydney and surrounding areas. Over the years, we’ve seen where many homeowners go wrong — and how the right planning and builder can make all the difference.
Here are some of the most common renovation mistakes to avoid — plus expert tips from our team to help you plan your project with confidence.
1. Underestimating Your Renovation Budget
One of the biggest traps homeowners fall into is underestimating the true cost of their renovation. Council fees, engineering requirements, and unexpected site conditions like asbestos or poor soil can quickly blow out a budget.
💡32 Degrees Tip: Always allow a 10–15% contingency in your budget for unforeseen costs. Our team provides transparent, detailed costings during the design and planning stages to help clients avoid financial surprises once construction begins.
2. Ignoring Council Approvals and Building Regulations
Every renovation in Australia is subject to council approvals and building codes, especially larger projects like second-storey additions. Skipping these steps might seem like a time-saver initially, but it can lead to major fines or even forced rectification work.
💡32 Degrees Tip: Work with a licensed builder experienced in navigating council requirements. At 32 Degrees Building, we manage the entire approval process for you — from planning applications to final certification — ensuring everything complies with Australian building standards.
3. DIY Overload
While DIY can be rewarding, taking on structural or technical work yourself can cause serious safety risks or legal issues. Electrical, plumbing, and structural work must be completed by licensed trades.
💡32 Degrees Tip: Focus your energy on the finishing touches — like painting or landscaping — and leave the complex tasks to qualified professionals. Our integrated team of builders, engineers, and trades ensures every stage of your project meets safety and compliance requirements.
4. Choosing Materials Unsuitable for the Australian Climate
Our diverse climate means building materials must be chosen carefully. Using materials that can’t withstand Australia’s heat, humidity, or coastal conditions often results in warping, cracking, or costly long-term maintenance.
💡32 Degrees Tip: We source high-quality, climate-appropriate materials that are suited to your local environment — whether that’s bushfire-rated cladding, insulation for energy efficiency, or moisture-resistant finishes for coastal homes.
5. Poor Floor Plan and Layout Decisions
Many renovations fail because the layout doesn’t suit the way people live. For example, adding a second storey without considering how the staircase integrates with the ground floor can lead to awkward flow or wasted space.
💡32 Degrees Tip: Our design team works closely with clients to ensure their floor plan feels natural, functional, and family-friendly. We focus on layout, light, and lifestyle — not just looks — to ensure your new space adds genuine value to your home.
6. Choosing the Cheapest Builder
Choosing a builder based solely on price is one of the most costly mistakes you can make. The cheapest quote often means corners are cut, timelines blow out, and workmanship suffers.
💡32 Degrees Tip: Choose a builder with proven experience, clear communication, and strong reviews. 32 Degrees Building delivers fixed pricing, quality craftsmanship, and transparent timelines — so you know exactly what to expect.
7. Overcapitalising on Renovations
It’s tempting to add every luxury feature possible, but spending more than your property’s market value can backfire when it’s time to sell.
💡32 Degrees Tip: We help our clients strike the right balance between lifestyle upgrades and market value. Whether you’re building for growth or return on investment, our design consultants can guide you toward smart, value-adding choices.
Final Thoughts
A successful renovation starts with planning — not demolition. By setting a realistic budget, choosing the right materials, and working with experienced professionals, you can avoid the common renovation mistakes that derail many projects.
At 32 Degrees Building, we specialise in helping homeowners expand and modernise their homes through well-designed, high-quality second-storey additions and large-scale renovations. With expert planning and seamless project management, we make the process stress-free from concept to completion.

Building Your Dream Home: Plans First or Builder First?
Do You Start with Plans or a Builder First?
When embarking on a Second Storey Addition, Ground Floor Extension or Large Scale Renovation project, one of the critical decisions you’ll face is whether to start with architectural plans or consult a builder first. It’s a topic that often divides opinions, with some advocating for plans first and others for the builder-first approach. At 32 Degrees Building, we believe that choosing the builder-first approach can save you time, money, and unnecessary headaches down the road. In this blog, we’ll explore why it might be in your best interest to consult a builder before diving into architectural plans.

1. The Budget-Conscious Approach: One of the initial concerns when starting any construction project is budgeting. Will your dream design align with your financial resources? Architects are experts at creating beautiful designs, but they might not fully understand your budget constraints. By approaching a builder first, you can get an accurate quotation upfront, allowing you to make informed decisions about your project’s scope and financial feasibility.
2. Realistic Cost Assessment: Builders are well-versed in construction costs, market trends, and material expenses. When you consult a builder first, you tap into their expertise. They can provide valuable insights into cost-effective design choices and suggest alternatives that can save you money without sacrificing your vision.
3. Holistic Project Management: Opting for a builder-first approach means you’re not just receiving a quote. You’re partnering with professionals who can handle the preliminary aspects of your project, including architectural plans, engineering, and approval processes. This holistic approach saves you time, money, and the stress of coordinating various services independently.
4. Avoiding Costly Redesigns: Imagine spending a significant sum on independent architectural plans, only to discover that they don’t fit your budget or your vision needs adjustments. The cost of revisions or a complete redesign can be substantial. When you consult a builder first, they will work with you on your plans early on and provide valuable feedback, helping you avoid expensive changes later in the process.
5. Standard Preliminaries Simplified: At 32 Degrees Building, we offer a comprehensive preliminary service that covers all essential aspects of your project, such as architectural plans, surveys, BASIX compliance, environmental assessments, waste management planning, external colour scheduling, structural adequacy certificates, engineering plans, stormwater plans, Sydney Water Tap-In Approval, and assistance with the application process to Council or Certifier. Our bundled service not only streamlines the process but also offers cost savings compared to sourcing these services independently.
6. Cost Efficiency: Contrary to popular belief, obtaining preliminary services independently may not save you money. Our integrated package is designed to be more cost-effective while ensuring that all necessary aspects are handled efficiently.
Conclusion: In the pursuit of your dream home, the choice between plans first or builder first can significantly impact your project’s success. At 32 Degrees Building, we advocate for the builder-first approach, which provides you with a realistic cost assessment, holistic project management, and valuable insights to align your vision with your budget. Our comprehensive preliminary service simplifies the process and offers cost-efficiency.

How to make your home energy efficient
Make Your Home More Energy Efficient
Updated November 2025
Adding a second storey or ground floor extension to your home is a great way to accommodate a growing family or to create additional living space.
Are you considering a second storey addition or ground floor extension to your home, but concerned about the impact it could have on your energy consumption?
Fortunately, with today’s technology and design practices, creating an energy-efficient home is easier than ever before. This blog post will serve as your home energy efficiency guide. We’ll explore some ways to make your home addition both eco-friendly and cost-effective.

Heating and Cooling
For heating and cooling, the first thing you can do is choose a system that works with your specific needs. Options include split-system air conditioners, wall-mounted heating, and cooling units or ceiling fans. Consider natural gas, electric, solar power or hydronic heating to reduce your heating and cooling bills over time. Another way to reduce energy consumption is by using insulation, which will help to keep your home warm in the winter and cool in the summer. You can also install double-glazed or Low-E glazed windows to help prevent heat loss during colder months.
Hot Water Systems
Your hot water system is another major contributor to energy usage. Consider installing a solar hot water system to lower energy bills and reduce your carbon footprint. This system works by using solar panels to heat your water, which can then be stored in a tank for later use. An electric heat pump system is also a good option.
Lighting
Choosing the right lighting for your home will provide energy savings long-term. LED lights use far less energy and last longer than traditional halogens. They are also safe, reliable and can be used both indoors and outdoors.
Appliances and Technology
Many appliances and devices in our homes use significant amounts of electricity. Choosing energy-efficient options when shopping for new appliances like a fridge, dishwasher, washing machine or air-conditioner is a great way to reduce power usage. Even switching off appliances when not in use can make a significant difference to your energy bill.
Connected Home
A connected home is a smart home that uses technology to manage energy use. For example, you can connect your heating and cooling systems to a smart thermostat, allowing you to automate your home’s temperature settings. This means your home will always be at the perfect temperature and energy will be used efficiently as the system will learn your preferences.
Solar Panel/Photovoltaic Systems
A photovoltaic system is a type of solar panel that generates electricity when sunlight hits the panels. Once installed, you can power your home using energy from the sun, saving you money on electricity bills and reducing your environmental impact.
Batteries
Batteries are a great way to store excess energy and utilise it when needed, making your home entirely self-sufficient. Battery options like Tesla’s Powerwall allow you to store electricity generated by solar panels throughout the day for use at night when electricity prices are higher.
Rainwater
Incorporating a rainwater tank into your second storey addition or ground floor extension is an excellent way to increase your home’s energy efficiency. Instead of letting stormwater run off your roof, a rainwater tank can collect this water and store it for later use, reducing your reliance on mains water. You can then use this water for watering the garden or flushing toilets, saving you money on expensive water bills. In addition to its practical uses, using rainwater tanks is an eco-friendly solution that reduces your home’s environmental impact, making it a worthwhile investment in the long run.
Let us help you build an energy efficient Addition or Extension
Making your Second Storey Addition or Ground Floor Extension energy efficient can help reduce your environmental impact and save you money on energy bills. With a range of options available, from insulation and efficient lighting to renewable energy systems, there’s never been a better time to create an eco-friendly home addition or extension. No matter what your budget or needs, there are measures you can take to create a home that is sustainable, comfortable and cost-effective.
At 32 Degrees Building, aside from this home energy efficiency guide, we can help you along the journey toward an energy-efficient home addition or extension.

Our Construction Quality Assurance Standards
At 32 Degrees Building, we are committed to delivering exceptional quality and impeccable finishes for your construction projects. Our 32 Degrees Building Quality Assurance Program is designed to ensure that your build meets the highest standards of quality and completeness so that we can provide you with the confidence that your build has been built to code.
What is the 32 Degrees Building Quality Assurance Program?

The 32 Degrees Building Quality Assurance Program is an integral part of our commitment to building excellence. This program includes a detailed progress inspection and final inspection conducted by independent building inspectors. These inspections are crucial for maintaining the highest standards throughout the construction process and ensuring that all aspects of the build are up to code and quality benchmarks.
Progress Inspection
Our progress inspection is conducted following the rough in stages of the construction process. These inspections are designed to catch any potential issues early and ensure that the build is proceeding correctly.
Key Areas of Focus:
- Frames: Inspecting the structural integrity of the frames to ensure they meet design specifications.
- Cavity Drainage & Flashings: Checking that drainage systems and flashings are properly installed to prevent moisture issues.
- Rough-In Stage: Assessing the preliminary installation of electrical, plumbing, and HVAC systems before the plasterboard is installed.
Final Inspection
The final inspection is conducted just before the handover and the sign-off of practical completion. This comprehensive inspection ensures that every aspect of your new build is finished to the highest standards.
Key Areas of Focus:
- Internal Areas: Evaluating the quality and finish of all interior spaces, including walls, ceilings, floors, and fixtures.
- External Areas: Assessing the exterior finishes, including cladding, roofing and gutters
Detailed Reporting and Certification
Both the progress and final inspections culminate in a detailed reports that may highlight any defects or areas requiring attention. These reports are crucial for ensuring that any issues are addressed promptly and that the build meets our stringent quality standards.
Certification:
Upon the successful completion of the Progress Inspection and Final Inspection, a Certificate of Quality Assurance is issued. This certificate is your assurance that all quality requirements have been met, and your new build is ready for handover in perfect condition.
Integration with Other Inspections
Our Quality Assurance Program is conducted in addition to the principal certifying authority (PCA) inspections and engineering inspections. This holistic approach ensures that your build is not only compliant with all regulatory requirements but also meets our rigorous quality benchmarks.
Conclusion
At 32 Degrees Building, our Quality Assurance Program is a testament to our dedication to delivering the highest quality builds. By incorporating thorough progress and final inspections, we ensure that every project meets our exacting standards. Trust us to provide you with a home that is not only beautiful but also built to last.
What should you expect to pay before your build can start?
What Do Renovation Plans Really Cost?
To fund an addition or extension on your home, you may find yourself applying for a Construction Loan with your lender. This is all well and good, however, you may find that the lender will not formally approve and release funds until plans, Council approval and a Contract is in place outlining the progress stage payments of the build. So, to get to this point, how much should you expect to outlay? The short answer is that we find for most of our clients it’s around $25K-$30K to complete the preliminary stage – this is for preparation of all the documents required to start building. Here at 32 Degrees Building we break it down into two manageable costs for our clients and below is an explanation of the preliminary process to help you as a client understand what happens before we can issue contracts and start your build:Preliminary Phase 1: Design and development of your architectural plans
This is the start of your building journey with us. Here we coordinate a survey and engage the draftsperson to come out and meet with you. The draftsperson will talk you through your ideas, then design your initial concept plan to align to the quotation you have received. Usually, a few tweaks may be required and then you can sign off your concept plan and the full architectural drawings can be created ready for us to lodge for planning approval.
Preliminary Phase 2: Council Lodgement – Development Application & Construction Certificate OR Complying Development Consent
Once your plans are finalised (sitemap, elevations, shadow diagrams, floor plans etc..) the next step is where we will lodge your plans to Council or to a Private Certifier either as a Complying Development Consent OR as a Development Application and Construction Certificate
CDC or DA/CC fees will be advised once plans are developed and a Council fee quote can be provided. Here we obtain the additional relevant documentation needed in order for your build to be ready to start and this includes;
- Statement of Environmental Effects – Details the potential environmental impacts the proposed build will have.
- Waste Management Plan – Applies to all homes across Australia and explains how waste generated onsite will be managed, maintained and disposed of.
-
BASIX – The Building Sustainability Index applies to all residential homes across NSW and confirms the glazing and energy rating minimum that is required to comply to
-
Engineering plans and if a first floor addition a first floor certification to confirm your existing home will support the addition
- Hydraulic plan and certification – This is to confirm your stormwater connections and how we will connect to the existing or if there are upgrade to the existing needed
- Sydney Water check – To confirm that your build will not impact any of Sydney Waters assets
- Sewer Service Diagram – We obtain this for the plumber to see where the existing connections to the home are
- Long Service Levy – Applies to all residential works over $250K
- There may be additional supporting documents required (e.g. Bushfire Report, Flood Report, Acoustic Report etc…)
- and any other supporting documents as required
How long does this process take? Well, this all depends on the Council, the service providers and you as the client. We find that from planning to Council approval to issuing you with contracts can take around 3/4 months. Once your build cost and inclusions have been finalised and your HIA fixed price contract has been issued you can then provide these to your lender in order to finalise your finance approval.
If you haven’t built before or have no knowledge of the building and construction industry then preparing all of these documents can seem quite daunting. That’s why with us, you would have us as your main point of contact to do all of the hard work for you. We even liaise between yourself and the draftsperson to help you stay within your budget when developing your plans and address any of the questions you have about the build along the way.
To get started on your building journey with us, we ask you to download our packages or complete our pre-quote enquiry form and tell us what you would like to build, from there one of our team members will be in touch with you.
Why You Need to Vacate When Adding a Second Storey to Your House with 32 Degrees Building
Why You Should Move Out for 2 Weeks
Updated November 2025
When you’re planning on adding a second storey to your house with 32 Degrees Building, it’s essential that you vacate the premises for a minimum of two weeks. Here’s why:
Ensuring Your Safety and Comfort
Your safety and comfort are our top priorities. During the initial stages of the build, significant work such as demolition, electrical adjustments, and preparation are undertaken. These tasks can generate considerable noise, dust, and disruption, making your home an uncomfortable place to stay. By vacating for at least two weeks, your family can avoid these inconveniences and ensure a more pleasant living environment.
Protecting Our Team’s Safety
When we add a second storey, we deal with an existing dwelling’s structural and electrical systems. To ensure the safety of our team, we need to disconnect the power to the entire home for a two-week period. This precaution helps minimise any risks associated with live electrical work and structural changes, keeping both our workers and your family safe.

A Seamless and Enjoyable Building Experience
Our goal is to make the process of adding an addition as smooth and enjoyable as possible. With our extensive experience in building second storeys and extensions, we’ve learned what strategies work best. Following our move-out guidelines during build ensures your project stays on track while prioritising your family’s safety and comfort. We carefully structure our builds to provide you with the best possible experience.
