    Our experienced building designers and expert builders will guide you through the entire build process, from initial consultation to council approvals through to project completion.
  • 1. Single storey extensions
    If you're looking to increase your existing home's footprint without adding another level, a single storey extension is a practical solution. These ground floor extensions seamlessly blend with the existing structure, providing additional room for a new living area, extra bedrooms, kitchen, or any other desired space.

    Our design consultants can help you explore extension ideas that maximise your property's potential and enhance its value.
  • 2. Double storey extensions
    A double storey extension is an excellent choice for those seeking to maximise their property's potential. By building upwards, you can create a brand-new level, offering ample space for extra bedrooms, bathrooms, or even a dedicated home office or entertainment area.

    Our design and construction experts will work closely with you to ensure your home extension project meets all planning permissions and building permit requirements.
  • 3. Deck and patio extensions
    Embrace outdoor living by extending your home with a stylish deck or patio. These open-air additions enhance your living space and provide a seamless connection to your backyard or garden, perfect for entertaining guests or simply enjoying the great outdoors.

    From concept design to completed home, we'll help you custom design the perfect outdoor oasis.

Our house extension process

At RoomFour, we believe in a seamless and transparent house extension process, where you’re involved and informed every step of the way, from initial consultation to completed home.

1. Initial consultation

Your journey begins with a Discovery Call, where we’ll discuss your vision, requirements, and budget for your home extension project.  This allows us to understand your needs and provide expert guidance on extension ideas to enhance your living space and create your perfect home.

We then engage in a Feasibility and Sketch Design Study. This is the foundation stage and the most important part of your design process.  It will help you understand your goals, what you want to achieve, what your cost will be and a full analysis of your project, along with preliminary sketches.  Click here to find out more on ‘Build Cost Estimate’.

2. Custom design and planning

The information gained from the Feasibility and Sketch Design Study now paves a clear and direct path for our team of skilled architects to then start creating a custom-designed extension plan that perfectly aligns with your lifestyle, aesthetic preferences and goals. 

During this process, we provide comprehensive cost estimates, ensuring transparency about investments needed to bring your luxurious custom home to life, whether a single storey, double storey, narrow or sloping block, knockdown rebuild, or more.

3. Council approvals and permits

Navigating the intricate world of council approvals and building permits can be daunting. However, our experienced professionals will handle all the necessary paperwork and ensure compliance with local council regulations and planning permissions, making the process seamless for you.

4. Quality construction

Once the concept design and approvals are in place, our team of skilled tradespeople will bring your vision to life with meticulous attention to detail and a commitment to quality craftsmanship. 

We use only the finest materials and techniques to ensure a lasting and beautiful completed home extension that adds value to your property.

5. Project management & communication

Our dedicated project managers will keep you informed and involved throughout the entire extension project, from start to finish. 

Regular communication and progress updates ensure transparency and allow you to make informed decisions along the way, whether you live in the house during the build process or not.

Frequently asked questions

faq

The cost of a home extension can vary widely depending on the scope of the project, materials used and other factors, i.e., site access, complexity of the designs. To provide a price indication, projects on the lower scale call on standard configurations, structures and materials that are readily available, with installation of these finishes and materials in line with industry standards. This level of project sits at approx. $2,700 + GST per square metre and can still be architecturally designed.

Mid-tier projects with architecturally de- signed features and more luxurious specifications can often range between $3,500 + GST and $4,500 + GST per square metre. Meanwhile highly specified projects that are embellished with the finer materials and finishes can cost anywhere from $5000 + GST to $10,000 + GST per square metre. Note that these figures are for the build only. Items to be considered additional to these are site preparedness, demolition, technologies, basements, slopes, swimming pools and landscaping costs.

Building costs less than $2,500 + GST per square metre could be reached, however this cost would be without professional design – architecturally and interior – and could result in subpar outcomes. It’s important to do thorough research on all builders – mass, independent and their qualification levels.

These figures should only be used as an indicative guide as every extension and renovation are all unique and no two projects are ever the same.

At RoomFour, we promote early collaboration between an architect, designer and builder.  This way you will have a better chance of efficient cost management and creating a budget that works for you, avoiding project cost blowouts and time and money loss by possibly redoing the plans.  With this early collaboration you are setting the foundation for a smoother, more successful project that delivers the desired outcomes for everyone involved. At RoomFour, we offer this Early Contractor Involvement service.

Extending your home can be a significant investment, and understanding the costs involved is crucial. Factors like the size of the extension, materials used, and design complexity can greatly influence the overall expenditure. 

Obtaining detailed quotes from reputable extension builders is advisable to gauge an accurate estimate for your specific project requirements.

Most home extensions require obtaining planning and building permits from the local council. At RoomFour, we guide our clients through the extension build council approvals process to ensure compliance.

A well-designed extension project can provide the extra space you need as your family grows, creating a custom-designed dream home. It allows you to incorporate functional home designs that fit your lifestyle while potentially increasing your property value.

The timeline can vary depending on the complexity of the extension ideas, concept design, and the type of home extension you choose. However, most reputable Melbourne house extension builders should be able to provide an estimate during the initial consultation or design consultations.

Absolutely! Many master builders and home extension experts offer integrated design and building services. Their team of extension designers and design consultants can work closely with you to create a cohesive concept plan that seamlessly blends the new extension with your existing structure.

It is crucial to work with experienced architects who specialise in extensions. They can help you explore extension ideas that complement your existing home’s architectural style and materials, creating a harmonious transition between the old and new spaces.

HEAR FROM OUR CLIENTS

In order to find a company to do the renovations on my 110 year old Edwardian Workers Cottage in inner western Melbourne, I did a lot of research.I found Room4, and they seemed competent. But they were much better than competent. Peter and Michael explained all steps and aspects of the renovation process, including the likely problems we could find. They went out of their way to assist me, and they kept me informed in detail. They aimed for excellent quality while keeping to my budget. Their suggestions were always clever and helpful.I am so happy with the results, and my house is much more functional and modern, but still works in terms of keeping its cultural identity. I would recommend Room4.
Peter & RoomFour team has been incredible to work with. We've worked in collaboration in the past and delivered amazing projects together. Quick responses & attention to detail has helped clients have good reassurance and trust with Peter. I would always recommend them as a builder. As an interior designer, it's always hard to find good builders to execute your design for you, but Roomfour has exceeded my expectations of quality & good craftmanship!
RoomFour renovated my entire existing home and constructed the extension to full specifications from my designer while guiding the transition from old to new. The quality is exceptional, I couldn’t be happier.
Peter and Michael from RoomFour were great to work with. They communicated well, were clear about what work would be done and were accommodating with allowing us to pay over the period of the build. Nice blokes too.
