How Much Do Home Extensions Cost?

Extending your home is a great way to add value and function to your property without the need for relocating. Whether you have a growing family, need additional storage space or want to convert your garage into a games room, home extensions are becoming an increasingly popular option for homeowners.


In this blog we explore the costs involved in home extensions and if it’s worth it in the long run.


Common Reasons To Extend Your Home


There are a range of reasons to extend your home, including:


  • Additional bedrooms
  • Work from home spaces
  • Entertainment areas
  • Increased storage space
  • Additional car parks
  • Home gyms
  • Outdoor entertainment areas


And much more! Extending rather than moving is a popular option because it means you can stay in your desired neighbourhood, avoid the costs of moving and tailor your home to your exact living preferences.


What Factors Influence The Cost Of Home Extensions?


Several factors influence the cost of home extensions, including the extension's size, whether it's a ground or second-story addition, the design's complexity and the materials' quality. The choice between a basic or luxurious finish will affect the overall budget.


How Much Can You Expect To Pay For A Home Extension?


When it comes to costs, the average house extension ranges from $2000 - $4000 per square metre for ground-floor extensions and roughly 50% more for second-story extensions. That means an 80-square-metre extension ranges from around $160,000 to $320,000.

What Are The Most Common Types Of Home Extension?


Extensions range from simple room conversions to multi-story additions. A few of the more common house extensions include:


  • Decks or patios
  • Sunrooms
  • Granny flats
  • Outdoor living spaces
  • Home office extensions
  • Dining room expansions
  • Master bedroom extensions
  • Entertainment room extensions
  • Garage conversions
  • Bathroom, kitchen & laundry extensions


Keep in mind, that specific extensions such as bathrooms and kitchens require additional plumbing and electrical work, influencing their overall cost.


Tips For Saving On Home Extension Costs


As any homeowner knows, renovating or extending can be costly, so cutting costs where possible will help in the long run. We recommend:


Maximising the new space: Ensuring the new room or conversion adds maximum function and value to your home.


Exploring converting existing spaces: Changing the function of a room rather than adding a new one can significantly reduce costs.


Opt for budget-friendly materials and finishes: It’s no secret that luxury finishes and materials will impact costs. So where possible, use a budget-friendly option.

Are Home Extensions Worth It?


From an investment perspective, you need to weigh up the cost of the extensions against how much value it will add to your home. A well-thought-out extension could add between 5% - 20% to the overall value of your home, so it’s important to consider the costs to ensure you will still make a good return on your investment.


Do Home Extensions Add Value To Your Home?


Yes, a well-executed extension can enhance both the functionality and market value of a home, making it an appealing option for many homeowners.


Do You Need Any Approvals To Extend Your Home?


Structural modifications typically require council approvals and permits, including building and demolition permits, which should be factored into the project's budget. Working with a qualified and experienced builder will ensure you tick all the boxes when it comes to approvals and permits.


Tips For Finding The Best Builder For Your Home Extension


Choosing a reputable builder is crucial for the success of the project. You should verify the builder's qualifications, insurance and references, and ensure clear communication regarding expectations, timelines and costs.


How Long Do Home Extensions Take?


The timeframe for completing a home extension will vary depending on the project's complexity, approval processes and the availability of materials and labour. You should discuss expected timeframes with your chosen builder before entering into an agreement.


Conclusion


Extending a home represents a significant financial commitment and requires careful planning and consideration. By understanding the factors that influence costs and the potential value added to the property, homeowners can make informed decisions that meet their needs and enhance their living space.
