A home extension involves expanding the existing structure of a house to create additional living space, such as adding extra rooms, a new floor, or expanding existing rooms

Choosing to build a home extension is a significant decision. However, due to you and/or your families needs and lifestyle changes, a home extension could be the perfect, cost-effective option. Here are some reasons why people choose to build home extensions:

  • Location: The big advantage of renovating and/or adding a home extension in Adelaide is that you get to stay in an area you have grown to love. Additionally, this option provides practical aspects such as keeping the kids in the same school, friends and family you can rely on in your neighbourhood, and having access to local amenities you are already familiar with.
  • Increased Space: One of the most common reasons is the need for additional space. This could be due to a growing family, the desire for a home office, or the need for extra storage.
  • Avoiding the Cost of Moving: With property prices at a premium and the cost of moving by no means small change, more of us are choosing to add a room rather than sell and move. Moving to a larger home can be expensive when you consider real estate agent fees, closing costs, and moving expenses. Building an extension might be a more cost-effective solution.
  • Customisation: Building a custom home extension in Adelaide allows you to tailor your home to meet your specific needs and design preferences. By designing and building a custom home extension with our award-winning team, you have more control/input over the layout, features, and overall aesthetics.
  • Increased Home Value: A well-designed and well-executed home extension can increase the resale value of your property. It can make your home more attractive to potential buyers if you decide to sell in the future. By choosing Adelaide’s best local, custom home builder, you can trust the local knowledge and experience that Finch Constructions has to offer.

Before deciding to build a home extension in Adelaide, it’s crucial to carefully consider your budget, local council regulations, and the potential impact on your daily life during the construction process. Consulting with Finch Constructions professional and passionate team can help you assess the feasibility and cost-effectiveness of the project. We are always committed to providing a rewarding building experience for all of our clients.

  • Carport, verandah and pergola extensions: There are many reasons to convert or expand your garage. Extending or converting a garage is simple, choosing what to do with it is the difficult part. Originally intended to house cars, the garage can be turned into a unique living space with a little ingenuity. Commonly narrow and long, garage conversions can seem impractical and may involve some remodelling in order to integrate additional square footage. Our experienced Adelaide home extension specialists can knock down or re-position walls as part of your garage conversion to maximise the potential of your extra space.
  • Extend your home during renovations: Home extensions can be carried out at the same time as existing home renovations which can provide a speedier project completion, meaning our contractors will not have to return to complete the works.

As members of the Housing Industry Association (HIA), we’re provided with many valuable resources on the latest legislative codes and standards which ensures that we remain current and that your project will be carried out with minimal difficulties. We also have various reputable contractors and suppliers of high-quality workmanship and products which enable us to provide the best possible product and finish to each of our extensions.

Planning permission requirements vary depending on factors such as the size and location of the extension, local zoning regulations, and building codes. Our local and specalised team will assist you with this if required.
The duration of a home extension project depends on various factors, including the size and complexity of the extension, any planning or regulatory requirements, weather conditions, and contractor availability. Typically, it can take several months to complete.
The cost of a home extension varies widely depending on factors such as the size, scope, materials used, labor costs, and location. After your initial site consult with one of our builders; our reputable team will provide you an in depth quote listing all associated expenses, including permits and design fees for your specific project.
