Obtaining council approval/planning permit will depend on zoning, overlays and other constraints which may apply to the land.  Checking with local council’s planning department can assist with your requirements.  At RoomFour, we do a full check and our architects and designers provide a full comprehensive planning permit service, ensuring your project is compliant with local regulations and can handle everything from initial consultation to final approvals, so you can focus on bringing your project for life.

Home extensions are usually more complex in comparison to constructing a new home as there are works being conducted around an existing property and looking to marry old with new, along with possible works being conducted to the existing part of the home.  A time frame is all dependent on scope, size, build quality, complexity of design and site access.  At RoomFour, from the early stages we can provide a close approximation of the time frame needed to complete your home extension, along with reasoning as to why your project requires that designated time.  Prior to construction, RoomFour also produce a detailed timeline which your Project Manager will keep you informed of on a regular basis.

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. $2,500 + 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 $2,000 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.

This will depend on the scope of your home extension and whether the existing part of the home will be renovated.  At RoomFour, we put our client’s safety as a priority.  We will work with you to create a plan that minimises disruption to your daily life.  This can be defined either at the early stages of your planning or once structural specification is completed.

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 are bound by The Domestic Building Contracts Act 1995 (Vic) which is required by all Victorian Registered Building Practitioners and must supply a statutory warranty which lasts for 10 years from the date of practical completion.

At RoomFour we have a team of architects and designers along with a team of other consultants and professionals that can provide a complete range of building design and interior design to facilitate all manner of home extensions and renovations.  We manage every aspect of the process with the collaboration of our designers and consultants.
