A smart approach to estimating home extension costs

Taking a smart approach to that home extension you’ve had in mind for so long can mean fewer cost overruns that don’t spoil your enjoyment of the final result. Make some cost estimates using this handy information.

What will the materials cost?

Planning an extension can be so fun that it’s easy to include all of those awesome home features you’ve been dreaming about. However, you need to know how much each feature costs to be sure you can bring your project in on budget. There can be a substantial difference in the cost of home extension projects even if similar materials are used, and it comes down to the cost of some of those items you want to include. You can make some astute compromises without sacrificing aesthetics.

Consider these examples:

Kitchens are usually one of the more expensive parts of a renovation or extension and could cost several thousand dollars, but a huge chunk of this cost is mostly due to pricey appliances. Careful choice of appliances can make a huge difference.

Roofing materials vary considerably in the options available and their costs, including installation.

Getting better insulation and temperature control systems can be expensive upfront, but they offer good savings on energy costs.

Flooring materials are another area where costs can skyrocket. Timber is appealing, but alternatives such as bamboo or contemporary laminates can be just as attractive for less cost.

What about any fees and services costs?

There are quite a number of fees and services you’ll need to pay for. You might have to pay for something without even building anything yet if your project requires council approval. Costs here include having plans drawn up by a professional architect or draftsperson. Don’t forget the building inspector or other certifying professionals that must be involved throughout construction. Some may also have to pay for a structural engineer or a building surveyor.

These can add up, so it’s wise to systematically calculate estimates of costs before you even get quotes. It means you are armed with information before you get building quotes and start to compare them. You’ll have a better understanding of what must be included and any specific requirements you have. It’s best to put in a detailed description of your building project when you post a job. This way, builders, architects, or project managers can give you their best estimates.
