Typical Costs Involved in a Home Extension

When you first move into your new home, you may not think too far in the future and whether the property will be large enough to cope with a growing family. However, one day you’ll wake up and realise that you don’t have enough space, and it’ll be time to decide whether to move to a bigger place or stay put and extend. 

As you already know, moving home can be both expensive and time-consuming. However, while extensions can give you the extra space you need and add value to your home, you need to consider how much an extension will cost. So, before you make your final decision, here are some typical costs to consider when adding home extensions Sydney wide. 

Typical costs of house extensions in Sydney

The final cost of your extension will be based on the size and type of extension and what you’re going to include within the extension. However, as a rule, house extensions Northern Beaches wide will cost between $2050m² and $3875m² depending on the type of construction you choose and the quality of the materials, fixtures and fittings. Of course, this figure could be higher if you decide to use more expensive build materials and internal fittings. 

If you’re choosing to add additional second storey home extensions Northern Beaches homeowners should expect to budget an extra 50% more than you would for a simple ground floor extension. This is because your second storey doesn’t require the foundation work needed for ground floor additions. 

Other house extension costs to consider

When it comes to costing house extensions Sydney builders advise that in addition to allowing for basics such as roofing, windows, doors, cladding and insulation, you should also include other costs such as: 

·         Costs associated with architects plans and planning applications

·         Excavation work

·         Heating and air conditioning

·         Bathroom and kitchen fittings – if applicable

·         Flooring

·         Painting both internally and externally

·         Furnishings

Remember that your builder will normally quote you for the building work; other items such as furnishings, blinds, curtains and lighting will all need to be included in your final budget too. You should also consider additional costs associated with fitting new kitchens and bathrooms. 

For example, a typical bathroom renovation could cost anywhere between $5000 for a budget bathroom to $25,000 for a top-of-the-range luxury bathroom, while kitchen renovations can range from $10,000 to $35,000.

Always leave room for contingency when planning a home extension

Remember that your house extension will incur more costs than simply the cost to build the structure, so you should always consider everything involved before you commit to this kind of work. 

If your plans are proving to be too expensive, it may be worth building a smaller extension or rethinking the quality of the fixtures and fittings to save money. 

And don’t forget to always set aside a percentage of the overall cost as a contingency fund to cover any unexpected bills that may arise.
